Hari Ramachandran received his B.Tech. from IIT Bombay in 1982 and his Ph.D. from the University of California at Berkeley, both in Electrical Engineering. He was a research scientist in the Physics Department at the University of California, Los Angeles for five years before returning to India. He was a scientist at the Institute for Plasma Research, Gandhinagar, from 1993 till 2001 and joined IIT Madras in Nov 2001.

The tenet group has a great deal of experience in the development of Access level networking systems. This strength lies in the group's expertise in all the related areas of the technology, including the optical layer, the electronic subsystems, network management systems and protocols. My own interests are in the area of the optical physical layer, including both access links and backbone link design.
Modern optical systems exhibit a variety of interesting phenomena, many of these nonlinear in nature. My interests are mainly in the areas of
We are in the process of developing inhouse a full set of numerical tools for the investigation of optical communication problems. These include
Plasma Systems are notoriously complex, and never more so than in the edge. A large part of my work has related to understanding the behaviour of plasmas in the sheath and presheath. The goals of my research are to understand better some of the following:
I am developing a particle simulation code to focus on sheath and presheath physics. Issues that have already been investigated include the identification of the sheath and presheath about a dust particle, study of wave fluctuations in an afterglow plasma, the effect of magnetic fields on plasma accretion, etc.
