[2] Starting in August 2018, he served as the Associate Dean for Curricular Affairs and Director of the Core Program at Occidental College for four years.

His research interests include computational fluid dynamics for aerodynamics,[1][2] nonstandard finite difference schemes, and the application of mathematical models to unusual phenomena such as the financial performance of movies.

[6] After returning to Occidental he was promoted to Full Professor in 2014 and served as interim department chair for three semesters starting in Fall 2015.

[8] His term as Associate Dean for Curricular Affairs and Director of the Core Program at Occidental College ended in August 2022.

He has published multiple papers that show how to use nonstandard finite difference schemes to produce approximations to solutions of the Liouville–Bratu–Gelfand equation in one-dimension[9] and in cylindrical[10] or spherical[10] coordinates.

[1] He organized a mailing list associated with LGBT meetups at the Joint Mathematics Meetings; this group of people evolved into Spectra.
