Professional Information

I have been faculty in the Department of Mechanical Engineering at the University of Wisconsin-Madison since November 2005. I am an Associate Professor since 2011, affiliated with the Department of Electrical and Computer Engineering since 2012. My research interests are in Computational Dynamics and High Performance Computing. In 2006 I established the Simulation-Based Engineering Lab. In late 2012 I also started together with several colleagues the Wisconsin Applied Computing Center at the University of Wisconsin-Madison.

I graduated in 1992 from the Polytechnic Institute of Bucharest, Romania, with a major in Aerospace Engineering. My Master-equivalent thesis was done under the supervision of Prof. Sorin Mitran. I received my Mechanical Engineering PhD in 1998 from the University of Iowa, under the supervision of Prof. Edward J. Haug. I worked until the end of 2004 for MSC.Software (among others, with Nicky Olrandea, Gisli Ottarsson, Todd McDevitt), in Ann Arbor, Michigan, where, on the side, in 2004 I was an Adjunct Assistant Professor in the Mathematics Department, thanks to Prof. Robert Kransy's support. In 2005 I was a Visiting Scientist at Argonne National Laboratory, working with Dr. Mihai Anitescu on numerical methods for electronic structure computation.
