Short Biography

Dr. Kartik Jain was a post doctoral researcher in The Interface Group, focusing on the computational modeling of flow and transport in kidneys. His main research interests are computational modelling of transitional, turbulent and physiologic flows on high performance supercomputers.

Kartik obtained a Doctoral degree in Mechanical Engineering (Dr.-Ing.) with a distinction (summa cum laude) from the University of Siegen in Germany, prior to which he acquired a masters degree in Mechanical Engineering with a specialisation in Simulation Sciences from the RWTH Aachen University, Germany. His doctoral dissertation explored transition to turbulence in hemodynamics of intracranial aneurysms and hydrodynamics of the cerebrospinal fluid in the spinal canal. The core work of his thesis employs massively parallel computations using Lattice Boltzmann Method to explore the onset of flow-transition in physiological flows at minutest spatial and temporal scales. Before moving to Europe, he acquired a Bachelor degree in Control Engineering from Kurukshetra University, India and then worked as a software developer in a leading IT company.
