About
My current research involves investigating the collective behavior of the motion of biological molecules such as motor proteins and ribosomes utilizing a Markov model namely Totally Asymmetric Simple Exclusion Process (TASEP). TASEP is a non-equilibrium model in which particles move in a preferred direction along a one-dimensional discrete lattice. Since almost all kind of real-life transport processes including vehicular traffic, pedestrian flow, intracellular transport carried out by molecular motors and ribosomes, involve significant randomness in their evolution which makes it very challenging to predict their future behavior. Also, all these systems keep changing with the environment due to which they fall into the category of not-equilibrium systems. Unfortunately, there is no fundamental theory to extract the properties of a non-equilibrium system as we have for equilibrium systems. Therefore we use TASEP not only to mimic the real-life transport process to understand them in a better way but also to observe new unexplored features of out of equilibrium systems. Majority of my problems are motivated by the motion of the motor proteins which are tiny biological machines moving along macromolecular highways namely microtubules for the proper functioning of a biological cell. I obtain the theoretical results using tools of Statistical Physics and Mathematics and validate them using Monte Carlo simulation and experimental outcomes from the literature wherever available.
