Brent received his Ph.D. from the University of Massachusetts, Amherst in 2006. His graduate work focused on models and algorithms for improving access to organized information with applications to web site design and optimal decision making.

During the final year of his graduate studies, Brent helped several other computer scientists start Adverplex — a company dealing primarily with pay-per-click advertising.

Brent is now the CEO of Valt Inc.


Brent is currently working on new models and algorithms for categorical organizations of information — particularly organizations involving tagged data. He is also searching for new approximation algorithms and hardness results for several coding problems.
