My friend Dibyendu Das, who is an associate professor in the physics department of IIT Bombay India will be visiting CSU from May 10-24 2011 as an APS-IUSSTF Professor. Dibyendu is a theoretical physicist who works on non-equilibrium statistical mechanics. As part of the APS-IUSSTF Professorship, he will be delivering a lecture series at CSU titled “Study of stochastic processes in certain physical and biological systems” hosted by the Dept of Chemical and Biological Engineering.
The lectures will be held in Glover 201 on May 16, 18, 20 and 23 The lecture on May 16 will start at 11am and the subsequent ones at 10 am. There will be coffee and refreshments.
The following is a brief outline of the lectures.
May 16 11 am – 1 pm
Lecture 1: Phenomena of collective migration of active matter — birds, bacteria, driven granular matter, cells, and actins — will be introduced. Other phenomena involving stochasticity, namely polymer motion, and microbial evolution will also be discussed. Some statistical models to understand these phenomena will be discussed. Mathematical similarities of some of these models will be mentioned.
May 18 10 am – 1.30 pm
Lecture 2: Basics of statistics. Random variables to stochastic processes. Two simplest linear processes — Random walk problem, and the growth/autocatalytic process. Similar analytical methods to treat more complicated problems — flexible polymers, and mutating bacteria.
Mathematical approaches using Master equation, and Langevin equation.
May 20 10 am – 1pm
Lecture 3: Numerical methods — Kinetic Monte Carlo, Molecular dynamics, Langevin dynamics. It will be demonstrated how the discussed numerical approaches have been used to obtain recent research results on
— (i) collective cell migration, (ii) collective motion of active/granular matter.
May 23 10 am – 1.30 pm
Lecture 4: Analytical Methods — It will be demonstrated how the discussed analytical approaches have been used to obtain recent research results on — (i) polymer motion in flow fields, (ii) microbial population dynamics.
