I am an Assistant Professor at the School of Computer Science at the University of Oklahoma. I am primarily interested in designing and analyzing machine learning algorithms with rigorous guarantees.
In particular, I have done work on the statistical and computational efficiency of supervised learning algorithms providing complexity or empirical bounds, or computational hardness results, within the context of adversarial supervised learning (different noise models, poisoning attacks, adversarial examples), randomized and local-search heuristic methods (evolvability), multiple-instance learning, and imbalanced data.
During the last couple of years my students and I are investigating semi-supervised learning, learning with streaming data, regularization methods, and related topics.

It appeared in the AI Magazine, Volume 45, Issue 1, 2024.
Another recent paper is
ISAIM-2022: international symposium on
artificial intelligence and mathematics,
This was written jointly with
Martin Charles Golumbic and
Frederick Hoffman with whom we organized the
International Symposium on Artificial Intelligence and Mathematics (ISAIM) 2022.
This is a foreword written due to the organization of ISAIM 2022.
The foreword appeared in the Annals of Mathematics and Artificial Intelligence, Volume 92, pages 1–4, (2024).
Last year I had the following paper:
-
Perceptrons Under Verifiable Random Data Corruption.
Work done jointly with Jose Aguilar Escamilla when he was an undergraduate McNair Scholar.
Appeared in International Conference on Machine Learning, Optimization, and Data Science (LOD), 2023.
