Biographical Sketch

Andreas J. Schriefl holds a Bachelor's and Master's degree from the Graz University of Technology, Austria, where he has a background in Engineering Physics. During that time he specialized in Materials Science with a concentration in silicon processing technologies. In cooperation with Infineon Technologies Austria AG he investigated surface defects caused by boron doping during his Bachelor's thesis, and bulk defects caused by proton doping through positron annihilation spectroscopy methods during his Master's thesis. After completing his Master's degree with distinction, Andreas started his PhD in Biomedical Engineering in February 2010 at the Institute of Biomechanics, Graz University of Technology, Austria, with an international research group under the direction of Prof. Gerhard A. Holzapfel.

His work focuses on experimental biomechanics, nonlinear optical imaging techniques and related mathematical analysis with the aim of studying the structure and mechanical properties of human arterial walls. Towards that end Andreas actively works with researchers from various fields and universities in Austria and abroad, and specifically spent several months performing research at the Yale School of Engineering and Applied Science at Yale University, USA, under the guidance of Prof. Jay D. Humphrey.
