Jordan Klein is a demographer and social epidemiologist whose research centers on the spatio-temporal evolution of mortality disparities, particularly in the context of emerging and re-emerging infectious diseases. His work integrates migration, mobility, climate change, and social inequities as key drivers of health outcomes. He employs a wide array of data sources—such as official vital statistics, surveys, digital trace data, and geospatial information—and advanced methodologies including machine learning, mechanistic modeling, causal inference, and demographic measurement.

His recent publications reflect a strong focus on the societal impacts of the COVID-19 pandemic, including modeling socioeconomic inequalities in mortality, estimating migration shifts using social media, and developing strategies for epidemic control in informal settlements. He also investigates broader issues like climate change and health transitions in urban Madagascar and data challenges in ancestry categorization in U.S. surveys.

Jordan is committed to open science, sharing data and code publicly. His work bridges demography, epidemiology, and computational social science, contributing to policy-relevant insights on health equity and population dynamics.
