As of August 2026, I am a faculty member at the Institute of Mathematics, University of the Philippines Diliman. My research interests are mainly in elementary and analytic number theory, and additive combinatorics. Among many things, I study questions involving multiplicative and additive arithmetic functions.
I graduated with a PhD in Mathematics from the University of Georgia, under the supervision of Paul Pollack. Previously, I obtained a M.S. Mathematics from the University of the Philippines Diliman, under the supervision of Richell Celeste.
Before that, I received a B.S. Applied Mathematics from the Ateneo de Manila University.
