Jeff’s background in epidemiology has been applied to global health projects. He has led monitoring, evaluation and research departments for humanitarian and development agencies in low- and middle-income countries.

After earning his Master of Public Health degree at Tulane University, he lived and worked in Tanzania, Kyrgyzstan, Tajikistan, Afghanistan, and most recently Liberia where he served as the Director of Monitoring, Evaluation, Research and Learning for Last Mile Health. There, his department designed and implemented research with a special focus on access to health services in communities further than an hour’s walk from the nearest health facility. This work was used to improve the Ministry of Health’s National Community Health Assistant Program.

Jeff is interested in the application of geospatial methods in understanding and targeting inequities in disease burden and access to quality healthcare in remote and other special populations. Specifically, he studies how the health service environment influences health behaviors and outcomes in low- and middle- income countries, and has been developing and studying new methods for joining geomasked surveys with other spatial datasets using Bayesian methods and simulation studies.
