PS 762: Introduction to Computational Neuroscience

A major effort is currently under way to understand the operation of the central nervous system, and more specifically, of neuronal networks in the brain. This is of great importance at not only the theoretical level, but also for the possibility of understanding the causes and cures for diseases such as Alzheimer’s and Parkinson’s.

The approach presently being taken includes both experimental studies and theoretical and computational modeling to jointly address questions that arise in this area of research. There is an increasing need for scientists trained at the interface of these disciplines who possess a strong analytic background together with a solid understanding of biological phenomena.

The present course will teach students the basic set of mathematical and computational techniques required for them to pursue higher level research in the field of neuroscience. It would also prepare them, in part, to be able to move on to various industry jobs that require quantitative and analytic skills. For example, several pharmaceutical companies are actively seeking employees with the background to model and simulate processes on the computer prior to production and testing. The set of lectures will cover necessary techniques to be able to understand various biological questions, to address them mathematically and computationally and then to translate results into a language that is accessible to experimentalists. It is envisioned that students who pass this class will be able to immediately utilize their course work in either an experimental lab or on the way towards a PhD. Further the mathematical content of the course is sufficiently general that it will also allow students to work in modeling of biological problems outside of neuroscience, in fields such as genomics, protein signaling networks and even ecology.

This Pre-Ph.D. course will be accessible to final year students of the M.Sc.(Physics) program as well as those of the M.Sc.(Life Sciences) and that it could be an optional course in the M Tech. (Systems Biology) programme as well.

Pre-requisites: Calculus of many variables, a basic understanding of differential equations, ability to use computer software such as MATLAB and the ability to code in Fortran, C, C++ etc.

6. PS 616C   Molecular Materials(3 credits)

This course is designed to introduce students to the basic concepts of chemical interactions and the principles and theories involved in the design of new-age applicative materials e.g., molecular sensors and switches, organic light emitting diodes, electrochromic materials etc. This course will also emphasize on how the change in molecular design and molecular interactions can tune or modulate the properties of these materials. Principles underlying the organic/inorganic synthesis and purification of materials through well-known named-reactions will also be covered in a lucid manner.
This course will be inter-disciplinary in nature and would help understand the basic theoretical as well as practical aspects (design, synthesis and properties) of new materials.

[Introductory classes would be planned for physics students]
