2.1. Research Achievements
Consistently demonstrated excellent research performance: My research
performance has been critically assessed over the past 6 years through the HKU
Performance Review and Development (PRD) Exercise by my senior colleagues
and mentors, Prof Gray Williams and Chair Prof David Dudgeon, and my
department head, Prof Rudolf Wu. I have been awarded “A or A+” grades with
“Excellent Performance” being noted consistently. This peer review based
Thiyagarajan CV Page No.2
performance exercise is a good indicator of my excellent research performance at
HKU.
Interdisciplinary research team: I have successfully established an
interdisciplinary research team consisting of highly talented graduate students,
research assistants and Post-docs with complimentary research skills. Within 6
years, our team has grown and our expertise now spans across many
interdisciplinary research areas including ecology (got 3 GRF grants), engineering
(got 4 GRF grants) and biomedical science (now applying for a new GRF).
Unique research approach: My interdisciplinary collaborative approach to
research and my committed and determined attitude yet flexible nature fosters a
conducive environment that allows my outstanding graduate students (1st class
honors students from engineering, medical and science faculties) to cross
traditional disciplinary boundaries to expand their expertise in the research field
of larval biology.
Excellent research output: My research efforts over the past 6 years at HKU have
been very productive resulting in 60 research articles during this period (please
see section 2.9 for details).
Exceptional grant application success: Our lab has received our 6th
highly
competitive GRF grant from HK-RGC and 6th
HKU Seed grant in a row. To date,
our 100% grant application success has secured >8 Million HK Dollars to
perform world-class “interdisciplinary/multi-institutional” collaborative
research work in HKU (please see Table 1).
Interdisciplinary collaborations: We have established strong collaborations within
HKU and in Hong Kong and internationally to allow us to carry out our
interdisciplinary research projects aimed at studying climate change effects on
marine organisms at the developmental, biomineralization and proteomics levels
(please see Table 2).
Links with industry: We have been working very closely with researchers and
oyster cultivation industries in China, including Prof Yu from South China Sea
Institute (CAs, Guangzhou, China), Oyster Growers Association of Hong Kong,
Oyster hatchery industries in Malaysia (Prof Aileen Tan and Er Allan), allowing
us to study climate change effects on our edible oyster species and to apply our
scientific findings to end-users, the oyster farmers of South China.
2.2. Research Records
Our research team of PhD students and post-doc (s) from engineering,
science and medical disciplines are committed to interdisciplinary research
approach. We are working in close collaboration with Hong Kong and
international scientists (see Table 2a and b) to investigate the mechanisms
Thiyagarajan CV Page No.3
of how ocean acidification (OA) and climate change affect larval forms
of a variety of marine organisms.
Our recent research has shed light on the molecular mechanism of how
ocean acidification affects marine invertebrate larvae. We have observed
that warming or hypoxia can rescue the negative effects of OA on larvae
by up-regulating the energy related proteins and biomineralization
mechanisms (published in Journal of Experimental Biology and PLoS
One). Our study of the OA effects has contributed to this new and exciting
interdisciplinary research area and our use of proteomics and materials
engineering tools is dramatically transforming many academic fields.
I have been invited to five ocean acidification related international
meetings (held in Malaysia, Canada, Sweden, Japan and India) to discuss
the future of OA research and to establish international links - it is
rewarding to know that our collaborative research is being recognized
internationally by scientists working in the OA field and is a testament to
our dedicated interdisciplinary approach.
Author/co-author of 80 articles in peer-reviewed, international and high
impact journals within 10 years (7.5 articles per year).
Grants from outside Hong Kong: As Co-Investigator (international
collaborator), I have submitted a grant proposal to Norwegian Government
for funding our China (Hong Kong) and Norway Joint research work with
Dr Howard Browman from Norway.
High quality collaboration: Over these 6 years, my laboratory have
successfully done research in close collaboration with 15 local (Hong
Kong) and 15 overseas researchers.
Participation in more than 35 scientific conferences (six times as the
organizing committee, eight times as chair, 17 times as invited/keynote
speaker, and four times as a member of the jury) since 2008.
Principle investigator of ten highly competitive and successful research
grant applications (have received >8 million HK dollars within 6 years;
see Table 1) with a 100% success rate for grant applications since 2008.

2.4. Current Research Interests/Future Plans
Our primary focus is to understand the effects of increasing carbon
dioxide, hypoxia, elevated temperature and variable precipitation (climate
change and ocean acidification) on early-life stages (larvae) of marine
invertebrates at the developmental, molecular and ecological levels.
Currently, we are intensively using gel-free (2D nano LC-MS/MS)
multiplexed (iTRAQ) proteomics techniques to study the adaptive
mechanisms of larvae to climate change variables.
Thiyagarajan CV Page No.5
In collaboration with specialists in crystallography and X-ray diffraction
(XRD), we are also examining the effects of present and predicated future
coastal climate change scenarios on calcium carbonate nanomaterial (shell
structures) growth, structural and mechanical properties in larvae,
especially during their settlement and metamorphosis.
Our interdisciplinary (larval biology, proteomics, and bionanomaterial
science) collaborative research is focused on the mechanism(s) of how
larvae of several ecologically and commercially important marine
invertebrates (such as barnacles, tubeworms and oysters) are likely to
adapt or succumb to the natural and the projected variable in the climate.
Our work spans a range of scales, from individuals to populations, and
utilizes laboratory simulations of future climate scenarios, laboratory
bioassays, in situ enclosure experiments, and field experiments studying
the contrasting Hong Kong coastal environments.
Importantly, we are examining the effects of environmental stressors on
larval metamorphosis over multiple generations in hopes of addressing the
possibility of larval adaptation to the gradually increasing stressors in
nature.
Ultimately, we plan to link these early life stage responses and adaptive
behaviors to coastal zone management, biofouling control and mariculture.
2.5. Research Grants (Since 2008)
I am proud of our 100% grant application success rate since 2008. This
remarkable success has only been possible because of our interdisciplinary
collaboration, which has attracted substantial funding for our research. Notably,
two out of our four HK-GRF grants received 100% scores from external
reviewers and were given full funding support. As a principal investigator, I have
conducted four research-related consultancy projects and received a number of
external and internal research grants with a total value >7 million HK dollars
since 2008/09. I have also been involved in a number of interdisciplinary research
projects within HKU and with other sister universities in Hong Kong.
Interdisciplinary collaborative grant:
My association and grants I have got from the Centre for Marine Environmental
Research and Innovative Technology (MERIT-AoE), as Co-
opted member, has tremendously helped me to: 1) freely
collaborate with environmental engineers, and molecular
biologists locally in Hong Kong, 2) expose my research team
to 100’s of Hong Kong scientists, and 3) co-supervise
graduate students and share laboratory equipment without institute boundary.
Thiyagarajan CV Page No.6
Directed by Rudolf Wu, Chair Professor and Director of the School of Biological
Sciences, the University of Hong Kong, MERIT is one of only twelve Areas of
Excellence (AoE) in Hong Kong, and the only AoE selected for conducting
environmental research. Therefore, my official association with MERIT is a
milestone in my carrier development.

2.10. Evidence of Excellent Applied Research
Since 2008, I have successfully completed two
research studies for the HKSAR-RGC/UGC (as
listed in Research Grant section), which determined
climate change (ocean acidification and hypoxia)
effects on commercially important marine shellfish,
oysters and tubeworms. These first two projects can
be regarded as applied research in nature. The
following three examples demonstrating my
outstanding applied ongoing interdisciplinary
collaborative research projects.
Project 1: Biomineral properties as a function of rising carbon dioxide: the
mechanisms and consequences of this biomineral-environment interaction
Oyster shells are made up of composites of CaCO3 crystals and organic matrix.
Matrix proteins occluded in these naturally assembled composites to provide
shells with incredible mechanical properties. Using a multi-disciplinary
collaborative approach including environmental science and physical chemistry,
we are currently testing the hypothesis that oysters alter their matrix proteins by
suppressing the expression of shell forming proteins in response to elevated CO2,
thereby changing the shell mechanical properties.
Project 2: Biomineralization by tubeworms in the face of climate change:
challenges and adaptive mechanisms
The ability of larvae to successfully metamorphose and form their incredibly
strengthened protective shells is likely to be compromised in the face of rapid
climate change. Given this real threat, it is important to study the mechanisms of
how they can overcome multiple-climate change stressors. We are currently
testing the hypothesis that larvae will experience even stronger negative effects
from multiple-stressors interacting with ocean acidification due to the
physiological inability of larvae to raise their internal pH and calcium levels to
improve calcification in low-pH environments. Again, we are using cross-
disciplinary (marine biology, environmental science and molecular biology)
collaboration to verify this hypothesis, which will ultimately help us to understand
the mechanisms by which larvae might adapt or succumb to climate change.
Project 3: Biofouling in a changing climate
Climate and ocean acidification has already
begun to have negative effects on marine
organisms, especially on larval calcification and
metamorphosis as shown in the pictures on the
right. The results of this project (Marine Biology
160:1983-1993) provide important information
not only for OA research but also for antifouling industries in the face of climate
change.
Thiyagarajan CV Page No.25
3. Teaching
3.1. Teaching Philosophy
Four main ideas have shaped my attitude towards teaching:
Respect for students and teaching as a profession. Often, expressed in
simple things such as showing up to class early, handing papers back on
time, phrasing comments on papers politely, and being available to
students when they need advice.
A motivated student will learn more effectively. I try my best to keep my
students motivated at all times in and out of class.
Writing (presentation methods) develops hand-in-hand with critical
thinking and is one of the most important skills a student must develop.
Lecture note taking and rote memorization does not effectively
communicate information to students; therefore, emphasis should be
placed on experiential learning through lab and field observation as well
as through content and subject matter.
3.2. Research Postgraduate supervision
My postgraduate supervision philosophy: I expect and will help my PG
students to become “interdisciplinary” researchers, who will be fully aware of the
importance of “collaborative research” through direct experience. I will encourage
them to read current and past research literature in their field, to become familiar
with the key scientific question involved in their research, to learn the necessary
analyses and laboratory techniques, to present at scientific meetings, and
ultimately to publish papers in high-quality journals. I strongly believe in closely
mentoring them to achieve these goals. Moreover, knowing how to make
convincing arguments to funding agencies is an essential skill, and I encourage
them to seek funding for their own research from external agencies, even when
resources are available to cover their immediate needs. My track record shows
that I am successful in implementing these philosophies and have proven that
this is an effective way of PG supervision. For instance, my first PhD student
(Miss Vera Chan) has amalgamated ecology, material science and engineering
fields in her study of climate change impacts on marine organisms. She has
submitted her thesis on time and graduated in October 2013. Miss Vera Chan also
serves as a role model for the rest of the laboratory members by publishing five
papers even before her thesis defense, and she has established an international
research network for the benefit of my laboratory and for her own career
development.
I have had two successful (an MPhil and a PhD) graduates under my supervision.
I have also successfully co-supervised a PhD student (Dr Terence) with Prof Gray
Thiyagarajan CV Page No.26
Williams of HKU and a MPhil student
(Dr Sun Jin) with Dr Jian Wen Qiu of
Baptist University of Hong Kong.
Currently, I am supervising five PhD
students, two research assistants (they
are waiting for PhD places in my lab)
and two post docs (see summary table).
One graduate, Mr. Kelvin Wong, is now
working for the Genome Research
Center (HKU) as a Proteomics Expert
Officer. My PhD student, Dr Vera BS
Chan, won the Faculty of Science Best Teaching Assistant award (2012-13) for
her outstanding performance. Three of my current PhD students (Ackley Lane,
Dinesh Ram and Ginger Ko) have been invited to three international conferences
with full funding support (including the High-CO2 meeting held in USA, 2012) to
present our world-class research work and demonstrate our “interdisciplinary”
approach to training our graduate students at HKU. My current PhD student, Roy
Li, was the recipient of the University Postgraduate Fellowship (UPF).
3.3. UG and PG courses taught at HKU
Environmental Life Science (ENVS1002) is
the only undergraduate course that I am
fully in charge of and was designed by me.
A comprehensive evaluation of this course
will be able to demonstrate my teaching and
course effectiveness. I have been teaching
this course since September 2009 and have
completed this course four times. This
ENVS course is not compulsory but is a
faculty elective in block C (life and living).
This is one of the most highly appreciated
(by students) and successful courses in the
science faculty, which now has a full student
quota (80 students) from both science and
engineering students. Notably, the
evaluation of both the course and my
teaching by students for ENVS1002 have been consistently high (75% to 90%)
since 2009.
My teaching performance
is consistent and has been
graded as “Excellent”
throughout the past 5
academic years by both
students and my peer reviewers (average scores of 70% to 90%). Having
Thiyagarajan CV Page No.27
increased the contact hours and focusing on ‘Outcome Based Learning’, my SET
scores of the recent academic year 2012-13 have been greatly improved. My
teaching performance is already rated as very good to excellent for the School of
Biological Sciences and HKU.
I had the unique opportunity to design, teach
and to serve as course coordinator for the HKU-
UBC (University of British Columbia, Canada)
course on “Marine Science”. This experiential
learning course has proven to be highly
successful (SET scores for Teaching and Course
>85%) not only for stimulating student interest
in marine science but also in establishing a
strong teaching link (collaboration) between
HKU and UBC.
3.4. Below are some of the randomly selected Student’s comments on my
course and teaching effectiveness.
As seen in the following two plots, it is evident that my SET scores for both
course and teaching effectiveness have progressively increased since 2008. The
majority of students enjoy my courses and have given me positive feedback on
my course structure and teaching, which has helped me to achieve excellent
ratings in both teaching and course design within my 5 years at HKU. With this
continuing trend, I will soon reach SET scores >90% (as rated by peers and
comments from students), which will rate me among the top teachers of HKU.
This is certainly possible because I am keen on implementing outcome based
teaching (and evaluation) and field based teaching as part of my courses.

4. Service (administration)
4.1. Knowledge Exchange (KE)
I view KE activities as one of the vital services that is intrinsically interwoven
with research and teaching. Over the past 5 years, I have been engaging in a wide
range of KE activities through applied research (as shown in section 2.10),
educational delivery (e.g. inviting guest lecturers from outside of HKU),
knowledge dissemination (e.g. as student advisor in the community), and
expertise sharing (e.g. working with government organizations). I have
implemented the following strategic initiatives to achieve my KE related goals
and services.
Example 1: A More Sustainable Future for Hong Kong Oyster Industry
The oyster meat is
considered a delicacy
in Hong Kong and is
a part of our culture
and tradition. With
rapid population
growth, the demand
for oysters as a food
source is bound to
increase, especially in
Asian regions.
However, the market
for local oysters
continuously shrinks,
partially due to lack
of commercially
viable sustainable
aquaculture practice.
As a result, local
oyster businesses
have suffered
massive losses and
the sector is at the
brink of extinction.
The oyster farmers of
Deep Bay (Hong
Kong) have gathered
together and
expressed their
concern and have
been interacting with
HKU researchers on
mitigating the current problem and increasing oyster production. The ever-growing
Thiyagarajan CV Page No.31
demand for oysters needs to be met, perhaps by setting up a sustainable, healthy oyster
aquaculture program with government support which is part of long ter m solution to meet
the sea food requirements of the people of Hong Kong. Towards achieving this goal, The
University of Hong Kong held an oyster hatchery workshop during June 2015 which
brought together representatives from the industry (oyster farms), academician (scientific
researchers) as well as policy makers (government body) on a common platform to
discuss these issues. It proved to be a success as intellectual exchanges that took place
resulted in formulation of an integrated monitoring program with the industry and policy
makers coming forward to fund and initiate the program. Researchers at HKU
demonstrated techniques of successfully strip-spawning oysters, larval rearing, and
improved methods for increased spat yield. Communication was facilitated between
government representatives and the local oyster farmers, bringing forth interactions
between them and allowing them to understand the difficulties faced by each other.
Example 2: Science Workshop for Secondary School
Students - Exploring a Drop of Seawater
I have nurtured undergraduate students from different
departments (majors in chemistry, Biology and Ecology) to
form a team to explore opportunities to disseminate the
knowledge that they have gained from studying at HKU to
local school children. As a result, we recently received KE
grants from UGC-HK (>20,000 HKD) to conduct a
workshop for secondary school students in HK to study the
changing climate in “Exploring a Drop of Seawater”.
Example 3: Disseminating expert knowledge through co-teaching a course at
sister universities
Served as guest (specialist) teacher at
HKUST and took part in teaching
“Conservation Biology”, one of their key
undergraduate and PG courses. This teaching
service was acknowledged by my peers (Prof Gray Williams and Prof David
Dudgeon) and the heads of my school (Prof Rudolf Wu) and the HKUST
department head (Prof Karl Tsim).
Example 4: Co-teaching a course with UBC teachers at HKU for UBC students
Students and teachers from the UBC
spent two weeks at SWIMS during
their summer marine ecology
course. As the course coordinator, I
was able to act as bridge to establish
a teaching collaboration between HKU and UBC.
This interaction between HKU and UBC has been
very rewarding.
4.2. Swire Institute of Marine Science Advisory Board Member (2013-2016)
I consider being a member of the advisory board as one of my core services at
HKU. In this role, I can 1) advise the Faculty of Science on all academic matters
Thiyagarajan CV Page No.32
relating to SWIMS, 2) comment on the annual reports of SWIMS to the Faculty,
3) advise on the development of SWIMS and its programme of activities, 4)
advise on the appointment of staff at SWIMS, and importantly, 5) advise on
matters concerning research funding, fellowships, conference grants and other
awards for staff and postgraduate students who are wholly based at SWIMS.
4.3. Course Selection Advisor (CSA)
Since 2009, I have been serving as CSA for Ecology and
Biodiversity major. Through this key service, I have actively
engaged with 100’s of HKU undergraduate students, giving them
advice on course selection, and their majors and minors.
4.4. Staff-Student Consultative Committee (SSCC)
I am one of the key members of the SSCC of the School of
Biological Sciences, HKU. This is a forum where students can
raise any issues or concerns they may have about courses or
their academic life, and they can give feedback on the school majors, especially
on Ecology and Biodiversity undergraduate programmes. I often use the SSCC to
encourage the quick resolution of problems and give students a sense of
involvement in the management of their academic life.
4.5. Science Faculty Induction/Open Day Instructor
I am responsible for organizing and running the University
Open Days and Information Days for the majors in Ecology
and Biodiversity and Environmental Science. During these
events, I also give introductory talks about these majors to
interested school students and/or new first year BSc students.
4.6. Evidence of leadership and mentoring of junior staff
From August 2008, I am serving as one of the
resident scientist at the Swire Institute of Marine
Science (SWIMS). I love this position and try to
stay in the residence along with SWIMS
graduate students and post docs because it gives
me an opportunity to merge with SWIMS junior
staff members, understand their work. I have
effectively used this golden opportunity to
mentor juniors, especially postdocs. I am also
serving as team player and mentor for graduate students working at SWIMS, i.e.
regularly taking part in the discussion group organized by them to nurture their
research culture and ethics.
