Immediate Openings for Ph.D. Students: Openings are available and expected to be filled as early as Spring 2027 or in Fall 2027. If you are interested, please send me your CV/Resume, transcripts, publications (if available) and GRE/TOEFL scores (if available) for consideration.

I am also happy to work with motivated M.S. and undergraduate students at UNT on independent study and research projects. Familiarity with optimization, probability, and Python is helpful. Please see the Research page for an overview of ongoing directions.
