About me

General Profile

Welcome to my home page. I am Sunil T T (VU2SWX) aka Sunil Thomas Thonikuzhiyil, a self proclaimed geek and a world famous ham radio operator.(:D) . Currently, I am located in Trivandrum , India. I have been trying to put up these pages for quite some time now and is not complete yet. I am interested in many things, but unfortunately, I am master of none. You may find some write ups  that I wrote  on diverse topics over the past several years  in this blog. Nothing official about it. All the views expressed here are my own and no one else is responsible for them.

I was born and brought up in the beautiful hilly Idukki district of India. I belong to the Thonikuzhiyil family settled around Pala. After finishing my school, I joined Bachelor’s degree program in Electronics and communication Engineering at Mar Athanesius College of Engineering. I  graduated  in 1990 with a First Rank ( academic rank   is a useless thing which I realized afterwords).  Later, I did my M.Tech in Computer and Information Science at Department of Computer Science Cochin University of Science and Technology.. Finally, I  managed  a PhD from Department of Electrical Engineering IIT Bombay. My PhD adviser was Prof. Subhasis Chaudhuri .

I have been working with the  Institute of Human Resources Development(IHRD) since 1991. I have held various positions in IHRD until 2001. In 2001, I joined Kerala Legislative Assembly as the head of their computer division. I was instrumental in computerizing the Kerala Legislative assembly. After a 6 year stint, I left Kerala legislative Assembly in August 2007 to take up a teaching job at College of Engineering Attingal Trivandrum.

As to my personal habits, I like vegetarian food, some time drink a peg (if you offer it free as in free beer ), like cool music(mainly Indian classical stuff- I have a good collection:) ), movies , books etc. My political views are mostly liberal left. I was an ardent Pastafarian for long. But, of late, I am a follower of our Lord and Savior DINKAN.

Articles and Publications
I have written a few of them . Here is my profile on Linux Gazette. You can find some of them there.

You can also look at my google scholar listings.  My PhD thesis was titled,  “Target detection and sensor selection for electronic nose applications”. (At present,I am unable to post it online due to copyright issues  as I have contributed parts of it to a forth coming book.:) ). Please feel free to write to me if you need a copy for academic purposes.  You can order the book in question  from the publisher here.

Social media

I am fairly active on facebook.   I write about politics, science and technology.  Have a look at my profile here.  You are invited to follow me.


Can you  give a talk at my college ?

Yes and no.  I am interested in speaking to small groups who are likely to pursue a career in tech.  I am not interested in things like keynote address, inauguration and other bla bla.   I am particularly averse to long welcome speeches and   introductions.

Short hands on workshops in which I can  talk about a specific topic/subject are  my specialty.

Do you charge for your talks?

Yes and no.  In general, I am not bothered about money if I speak at publicly funded institutes/ colleges.  Please give me a good book  if you  want to  give a present. ( No plastic/glass items please).   For private institutes I charge handsomely:D ( especially if it is free software stuff.  Free software is not free beer).
