Hridesh Rajan

Overview

I serve as the Dean of the School of Science and Engineering at Tulane University and as a Professor in the Department of Computer Science. Before Tulane, I was the Kingland Professor and Chair of Computer Science at Iowa State University (2019–2024) and the founding Professor-in-Charge of Data Science Programs (2017–2019).

My research spans programming languages, software engineering, and trustworthy AI. I am known for the design of the Ptolemy programming language, which advanced modular reasoning about crosscutting concerns, and for Boa and its infrastructure, which lowered the barriers to data-driven software engineering at ultra-large scale.

I lead with a collaborative, outcomes-oriented style: building high-performing teams, launching programs that meet national needs, and creating partnerships that translate research into societal impact.

A single principle runs through our work: modular reasoning. We design the languages and interfaces that make it possible, scale it across millions of programs, and now carry it into AI-enabled systems.
