Jun Bo Lau

Hello World!

I am currently a postdoctoral researcher at COSIC, KU Leuven, working with Frederik Vercauteren. Previously, I was at Boston University, working with Jennifer Balakrishnan. I obtained my Ph.D. from UC San Diego under the supervision of Kiran Kedlaya.

My research interests sit in the intersection of number theory, algebraic geometry and computations. I am also interested in their applications to cryptography and coding theory.

Feel free to reach out to me at laujunboatgmaildotcom (with the obvious replacement).
