Till about 1990, my research interests closely related to the subjects
I was teaching such as, Computer architecture, Computer System Design,
Computer Graphics, Statistical Signal Processing, Microprocessor Systems,
Embedded Systems etc. The graduate students who worked with me during this
period worked in the general area of Computer Architecture and Graphics,
besides Statistical Signal Processing of Biomedical or Acoustic Signals.
The primary interest in Graphics related to Curve Design, as applied to
rendering text in Indian Scripts.
During the last decade,
I have concentrated on the problem of computing with Indian Languages and
designing software systems supporting user interfaces in Indian and other
South Asian languages.
There is not much
we do that qualifies as "Academic Research" but students in the Systems
Development Laboratory which I setup in 1976, have contributed to an important
project that has gained visibility in the country.
I have learnt hard
lessons in undertaking this exercise. Ours is a largely technology starved
society and "Does a technology savvy institution such as the IIT have any
role in bridging the divide between the sections of the society separated
by technology"? A decade of involvement with the real technology needs
of our country, at least in respect of education and literacy, has sharpened
our technical skills but has also reminded us of the new lessons to be
learnt. Please visit the pages of this site relating to "Software Design
Issues" for details of the project which has kept me and my students occupied
for the past fifteen or more years.
I now find that my
attention is increasingly drawn towards the problem of "Technology for
the Society" where one worries about introducing technology to a community
keeping in mind Social Relevance. Read about my views on "Technology

I retired from IIT Madras in March 2011 after a long
service lasting nearly four decades. When I joined IITM
as a student in 1962, my aspirations were to become a
teacher and these were fulfilled in 1973 when I returned
from graduate study at Yale and joined the faculty. At that
time the name IIT implied engineering skills.
Times have changed! At the time of my retirement, the
emphasis had changed from "down to earth engineering" to
"visibility through research". I cannot accept this but
it is inevitable that I keep quiet and not speak about it.
Technology now comes from outside the institution. The
responsibility no longer rests with the faculty to see that
engineering is sustained within. This absolves them of
accountability when things fail!
Good old Engineering provides for handling failures
gracefully. I do hope this principle will not be ignored
while teaching students how to make things work!
Expressing my gratitude
I wish to express my gratitude to the generations of my
students who have distinguished themselves in the
world as capable achievers. I have been lucky indeed to have earned their
respect (and now friendship).
