William Echols

I am a first-year Ph.D. student in Computational Applied Mathematics and Operations Research (CMOR) at Rice University. Before Rice, I obtained a B.A. in Mathematics with an emphasis in Operations Research from UC Berkeley.

In my spare time, I enjoy recreational computational problems. A selection of these projects is available here.
