Shannon Gallagher

Special Faculty, Lecturer
Carnegie Mellon University

I am a statistician and machine learning researcher interested in rigorous evaluation, interpretable AI, and responsible use of models in high-stakes settings.

Current teaching
Shannon Gallagher

Statistics for modern applications.

My work spans large language models, AI evaluation, infectious disease modeling, and statistical software. Before returning to Carnegie Mellon as faculty, I led machine learning research at the Software Engineering Institute and conducted postdoctoral research at the National Institute of Allergy and Infectious Diseases.

I earned my Ph.D., M.S., and B.S. at Carnegie Mellon University.
