**Research Interest:** I was a senior research fellow in Department of Mathematics, IIT Ropar from Aug, 2011 to July, 2016.
My research interest broadly includes modeling, analyses and Simulation of traffic flow through lattice hydrodynamic approach (one or higher dimensional).
The main applications of my research have in traffic flow, e.g. to eliminate accident, environment pollution problems and prevent traffic-transportation time.

**Research Interest:** I was a senior research fellow (CSIR) in the department of Mathematics at IIT, Ropar from July, 2010 to Sept, 1016. My research interests include broadly the study of non-equilibrium phenomena in driven diffusive systems using asymmetric simple exclusion process (ASEP). These processes have applications in biological intra-cellular transport, vehicular traffic and many stochastic transport phenomena relevant to physics, chemistry and information theory etc.

**Research Interest:** I was a senior research fellow (CSIR) in the department of Mathematics at IIT, Ropar from I am currently working on stochastic methods and statistical analysis of biological processes. My main interest is in regime shifts in nature and modeling cellular and genetic networks with a special focus on protein synthesis. I focus on identifying early warning signals of regime shift that are not fully explained by existing ecological theory.

**Present Position**: Postdoctoral position in University of California, Berkeley (Soon to join)

**Research Interest:** Presently, I am Research Scholar in Department of Mathematics, IIT Ropar. My research include the study of multi-channel exclusion processes, in particular asymmetric simple exclusion process (ASEP) which is a discrete model and is used to study different non-equlibrium complex phenomena in driven diffusive systems. In ASEP, particles move along the lattice by hopping between neighbouring sites that are vacant. Such processes are applied in many non-equlibrium phenomena like intracellular transport, vehicular traffic, surface growth, kinetics of biopolymerization, protein synthesis, transport of motor proteins in biological cells, modeling of ant trails and many stochastic particle systems far from equilibrium related to physics, chemistry and biology etc.
