Biographical Sketch

Dr. Igor Karšaj was born in Virovitica, Croatia, in December 22, 1975. He studied Mechanical Engineering at the Faculty of Mechanical Engineering and Naval Architecture (FMENA), at the University of Zagreb from 1994. For the achievements during his study he received the “Davorin Bazjanac Award” in 1996. He graduated in 1999 as one of the best students in his generation for which he received the “Medal of FMENA”.

In 2001 he was employed as a young researcher at FMENA, and started a postgraduate study. He finished his PhD Thesis on the “Numerical modeling of large strain elastoplastic deformations” in 2006 under the supervision of Prof. Jurica Sorić and Prof. Carlos Sansour from the University of Nottingham. The “Alexander von Humboldt” Foundation covered the costs for a four months scientific exchange at the Institut für Baustatik, Universität Karlsruhe, Germany. In 2005 he received “The Young Researcher Fellowship Award for exemplary research in computational mechanics” from MIT, Cambridge, USA. In 2006 the Croatian Ministry of Science, Education and Sport awarded him as the best young researcher in 2005. In the same year he received the annual award of the Society of University Teachers and Other Scientists of Zagreb for young researchers and artists. In 2011 he received the “Vera Johanides Award” from the Croatian Academy of Engineering for young scientists.

From 2006 on he is doing research on the biomechanical behavior of soft biological tissues. The main goal of his work is the modeling of growth formation in abdominal aortic aneurysms. In 2008 he was a Fulbright Fellow under which he spent ten months at Texas A&M University, USA. Since April 2013 he is a FWF Lise Meitner Fellow at the Institute of Biomechanics, Graz University of Technology, Austria.

He was a member of a few Croatian and international scientific projects. From 2011 on he is leading the Croatian Science Foundation – Instalation Grants Project.
