István Reguly, PhD is an assistant professor at the Faculty of Information Technology and Bionics, Pázmány Péter Catholic University. He obtained his the MSc and Ph.D degree from Pázmány Péter Catholic University in 2010 and 2014 respectively. He received the Pro Scientia Medal awarded by the Society of Pro Scientia Medalists and the Hungarian Academy of Sciences in 2011. Teaching activity at Pázmány Péter Catholic University includes: Mathematical Analysis I-II, Algebra and Discrete Mathematics I-II, Database Systems, Neural Networks, Digital Signal Processing, Information and Coding Theory, Nonlinear Dynamic Systems, Circuits and Systems, iOS Development, Cellular Neural Networks. His general area of interest is the abstraction and implementation of algorithms in different problem classes that on one hand raise the abstraction for domain scientists and on the other hand provide an efficient way of mapping execution to different hardware platforms. The main body of his research investigated the problem class of unstructured mesh computations, both in a very generic sense and in the specific case of sparse linear algebra routines on the graphical processing units. Other problem classes he have worked on include structured mesh computations and molecular dynamics.
