He studied variation of properties of galaxies in clusters, groups and filament environments in observational data as well as simulated data. He also developed and used a simple model to study ram pressure stripping of gas from galaxies. He defended his thesis in 2020 joined KIAS as a post-doctoral fellow.
Sandeep Rana. He worked on aspects of clustering of radio sources and its implications for epoch of reionization studies where these play the role of a foreground. Sandeep completed his PhD in 2019. He joined NISER Bhubaneswar as a post-doctoral fellow. At present he is working with ARP investments.

He visited the Harvard Smithsonian Center for Astrophysics as a fulbright fellow in 2010-11. He completed his thesis in 2011 and moved for a post-doc at the Max-Planck institute for Astronomy, Heidelberg. He moved to the Institute of Astronomy, Cambridge as a post-doctoral fellow before joining TIFR as a faculty member.
Nishikanta Khandai. He has done work on optimising the N-Body codes and development of an adaptive resolution code. These codes have been used to study aspects of gravitational clustering and also some aspects of the high redshift universe. He submitted his thesis in Aug.2009 and moved to Carnegie Mellon university as a Petascale fellow. He also did a stint as a post-doctoral fellow at Brookhaven National Laboratory. At present he is a faculty member at NISER, Bhubaneswar.
Jayanti Prasad. He started research work in early 2003. He has studied aspects of mode coupling in non-linear evolution of density perturbations with a special focus on the role of sub-structure. He also worked done work on quantifying limitations of N-Body simulations arising from the finite range of scales resolved in initial conditions. He completed his thesis in April 2008 and moved to a post-doctoral position at the National Centre for Radio Astrophysics, Pune. This was followed by a stint in different capacities at IUCAA, Pune where he worked with the LIGO team. At present he is working as a free lance consultant on data sciences and related issues.
Suryadeep Ray. His thesis work was on N-Body simulations and some applications. He finished his thesis work in early 2005. He is working with CGG, an oil exploration company he joined after completing one year as a post-doctoral fellow at IUCAA, Pune.
