RWB Stephens Prize Winners 1997

Andrew Bashford is currently finishing a PhD under the supervision of of Professor David Hutchins, Department of Engineering, University

Warwick, where he also obtained a BEng (Hon) in mechanical engineering.

To date, his research has concentrated on the design and application of air-coupled capacitance ultrasonic transducers. Typically, the appli- cations for these devices include through thickness imaging of compos- ites, polymers, and ceramics. Additionally, he has been designing high temperature. immersion, and focused capacitance transducers, for indu- strial applications, Presently, Andrew is not working with ultrasonics, but as a mechanical design engineer for the FKI engineering group, based in the United Kingdom. However. he hopes to return to research, ideally in acoustics.

His sporting interests include playing hockey, soccer, and mountain biking. Also, Andrew spends his spare time playing the piano, reading and when possible. travelling the world.

Anne Van Hauwaert was born on January l5th, 1970, in Turnhout. Belgium. In June 1993, she graduated at the Universite Catholique de Louvain as a Civil Engineer, having accomplished her dissertation in the field of hydraulics. In September 1993, she was appointed research assistant in the Civil Engineering Department of this university and from January to December 1994 was in charge of experimental projects in the Department’s laboratory.

In January 1995, Anne started a doctoral research in the field of Steel Fibre Reinforced Concrete. The main purpose of this work is to estab- lish the influence of the interfacial fibre-matrix bond on the macroscopic cracking behaviour of such composites. Bending tests are performed. during which ultrasonic wave propagations and acoustic emissions are used to point out the onset of cracking and follow the crack-advance in the material. On the other hand, the problem of the fibre-matrix bond has been approached from a numerical point of view, during a 6 month stay at the TU Delft, The Netherlands.

Her PhD is due to be finished in June 1999.

Stefan Knauth was born on March 12th I965 in Bad Homburg, Germany. He studied Physics from 1988 till 1995 at the University of Frankfurt am Main. His diploma project was the development of a scanning second sound microscope which was performed in the research group of Prof. Wolfgang Grill at Frankfurt University. This new type of microscope has been demonstrated in his contribution to the UI’97 conference.

After graduation Stefan worked as a computer specialist for several industrial projects, In 1996 he went to Leipzig University in Germany to work towards his doctoral degree. His team have developed a tech- nique for real space imaging of the ballistic propagation of electrons in solids using an electron microscope.

When not in the physics lab, Stefan still finds some time for hobbies which include water sports in the liquid and solid phase. He is also a fan of historical motorcyles which he likes to use during camping weekends.

lgal Ladabaum received a BS in Bioengineermg from U.C. Berkeley in 1992. He then went to Paris, France where he was a Jean Monnet scholar (199223) at the Ecole Polytechnique. He was also a staff engi- neer at Air Liquide. In 1996, he received an MS in Electrical Engineering from Stanford University. Currently a doctoral candidate at Stanford, Igal is interested in the techniques of micromachinmy and their application to the realization of novel transducers. Most of his etfort is directed toward the development and application of ultrasonic transducers. He is a member of the IEEE and the Acoustical Society of America. He has received numerous awards through the course of his studies, including being the student speaker at every commencement ceremony since 8th grade. He received the best student paper prize at the International Conference of Micro and Nano-Engineering in Aix en Provence, France, 1995. He has contributed several journal and conference papers, and is pursuing patents for some of his work on ultrasonic transducers.

When not at work trying to graduate. Igal can be found spending time with his family and friends, hiking, traveling, reading, eating, or sleeping.
