Biography

I am currently working as an Irish Research Council Postdoctoral Fellow.  I received the fellowship for the two year period beginning October 2018, for my project proposal on constructing combinatorial structures and codes.  My research interests are primarily in design theory, combinatorics, coding theory, algebra, and some applications of these branches of mathematics.

Detailed information is maintained on my personal webpage.
