Sridhar Chellappa awarded Best Doctoral Student of the Faculty of Mathematics
Mathematician Dr. rer. nat. Sridhar Chellappa was named Best Doctoral Student 2023 of the Faculty of Mathematics at Otto von Guericke University Magdeburg for his outstanding Ph. D. thesis.
He is a postdoctoral researcher at the Max Planck Institute for Dynamics of Complex Technical Systems Magdeburg in the research group Numerical Methods in Systems and Control Theory headed by CDS member Prof. Dr. rer. nat. Peter Benner. His doctoral thesis A Posteriori Error Estimation and Adaptivity for Model Order Reduction of Large-Scale Systems was supervised by Prof. Dr. rer. nat. Peter Benner and Dr. Lihong Feng (Team Leader Model Order Reduction).
Extensive computer simulations are necessary for modelling and understanding physical phenomena in many areas of science and technology. The time-consuming simulations can be accelerated with the help of Model Order Reduction (MOR) of dynamic systems. In his research work, Sridhar Chellappa has proposed new adaptive methods that substantially reduce the computing time of MOR. Sridhar Chellappa investigated chemical processes such as Batch Chromatography and Fluidized Bed Crystallization, a process to obtain pure crystals of a particular chemical compound.
