Welcome!

My name is Sitraka Randrianarivo, and I am currently pursuing a Ph.D. in the School of Mathematical and Statistical Sciences at Clemson University. My Ph.D. advisor is Dr. Felice Manganiello.

See my Clemson profile.

My research focuses on algebraic methods in coding theory. I am also interested in commutative algebra, algebraic number theory, and computational algebraic geometry, particularly in their connections with algebraic coding theory. My current work studies constructions of subspace codes for the analog operator channel, an emerging setting for subspace coding over the complex numbers.
