Mark P. Walsh

I am a Senior Research Associate at GiveWell, where I review the quality of GiveWell research and investigate cross-cutting questions that affect GiveWell’s grants. I hold a B.A. in economics, an M.A. in Public Policy, and a Ph.D. in economics from Stanford University. Between my M.A. and my Ph.D., I worked as a research associate at the Abdul Latif Jameel Poverty Action Lab. I enjoy basketball, hiking, prediction markets, and my two cats.
