Bidya Binay Karak is currently a Postdoctoral Fellow in the High Altitude Observatory of NCAR. He belongs to the NASA Living With a Star Jack Eddy Postdoctoral Fellowship Program, administered by the University Corporation for Atmospheric Research (UCAR).
Bidya completed his PhD from Indian Institute of Science, Bangalore in August 2013 and moved to NORDITA, Stockholm as a research fellow for two years. Before moving to Boulder in January 2016, he spent a few months in Max Plank Institute of Solar System Research, Germany as a visiting scientist.
Karak’s main research interests lie in Magnetohydrodynamics and its application in Sun and other stars, dynamo theory, astrophysical fluids, turbulence, convection, magnetic fields, sunspot and solar cycle, large- scale flows such as differential rotation and meridional circulation in the solar convection zone. During his PhD period, he was involved in understanding the origin and the evolution of Sun’s large-scale magnetic field, the solar cycle and particularly their irregular features such as the Waldmeier effect and grand minima using the Babcock-Leighton/flux transport dynamo models. Later he worked on turbulence and convection simulations in Cartesian geometry and recently on global magneto-convection simulations in solar convection zone using the Pencil Code. Currently, he is working on a 3D surface transport and Babcock-Leighton dynamo model, in which the tilted bipolar sunspots are placed at the surface based on the field at the bottom of the convection zone and the subsequent decay of these spots produces the poloidal field to maintain the solar cycle.
