Ashok received his bachelor's and master's degrees in Mathematics from the Manonmaniam Sundaranar University, Tirunelveli, in 1999 and 2001 respectively. He passed the CSIR-UGC (NET) for lectureship in Mathematical Sciences in 2001 and started lecturing Mathematics in various educational institutions until December 2007. During this period he developed an interest in Applied Mathematics. He obtained the CSIR-UGC (NET) for JRF in December 2007 and joined for a Ph.D programme in the department of Electrical Communication Engineering of the Indian Institute of Science, Bangalore, under the supervision of Prof. Rajesh Sundaresan. He completed his Ph.D in October 2014. Subsequently, he was a Visiting Scientist at the Stat-Math Unit of the Indian Statistical Institute, Bangalore from December 2014 to May 2015 and a post-doctoral fellow at the department of Electrical Engineering of the Technion-Israel Institute of Technology from May 2015 to December 2015 under the mentorship of Prof. Igal Sason. He was with the discipline of Mathematics of IIT Indore from January 2016 to May 2018. He joined IIT Palakkad in June 2018.

Research Group

We are looking for well motivated PhD students in the areas of Mathematical Statistics, Information Theory, Information Geometry, and Probability.

Interested candidates are strongly encouraged to get in touch with me by solving the problems (as many as possible) put up in this link and submit them (scanned copy of hand-written one or latexed one) by email to ashokm[at]iitpkd[dot]ac[dot]in.

(Remember that, it is not necessary that you should have answered the questions completely. You can submit partial solutions also. What we would like to see is your efforts to solve the problems.)

Interested candidates are also strongly encouraged to look at some or all of our recent works mentioned under 'Research' above to get an idea of the kind of works that we are doing.
