Ans Irfan, MD, EdD, DrPH, ScD, MPH, MRPL, MA, is a multidisciplinary global public health practitioner, learning and development
strategist, and climate-health expert with nearly two decades of experience advancing health equity across domestic and international contexts. As a committed, award-winning educator, scholar, and pracademic, his work spans Pakistan, China, and the United States, integrating cross-cultural insight with a systems-level understanding of public health, technology, and education.

Prof. Irfan is the founding director of The Public Health Praxis Center, an ecosystem of applied research, leadership and
capacity-building programming, and science communications, focused on mobilizing science for social impact. Some of the signature programs include the Praxis Fellowship, the Science for Social Impact Award, and the Inclusive Health Equity Literacy Scholarship. Key global initiatives include ClimatexHealth Technical Assistance Initiative, a climate adaptation technical assistance mechanism, and the Climate & Health Equity Practice Fellowship, a first-of-its-kind program designed to develop climate leadership among physicians in the Global South.

His expertise merges multiple disciplines, including climate justice, decolonial theory, global health, environmental and occupational health, health policy, migrant health, climate change, sociocultural anthropology, organizational change management, program development and evaluation, and implementation science. Using a mixed-methods approach, he designs interdisciplinary, practice-anchored public policy and programmatic interventions to reduce social and health inequities.

Beyond academia, Dr. Irfan serves as a Fulbright Specialist. He has advised and supported public health and policy efforts with national and global institutions, including UNESCO’s Inclusive Policy Lab, the American Public Health Association’s Center for Climate, Health & Equity, the Environmental Protection Agency, and the National Academies of Sciences, Engineering, and Medicine. He has also served as the founding director of the Center for Social Impact & Leadership at the DC Public Health Association.

He also serves as CFR Higher Education Ambassador at the Council on Foreign Relations. His previous educational leadership appointments include CET Faculty Fellow at the USC Center for Excellence in Teaching and Faculty Fellow with the Continuous Learning for Antiracist Curricular Change (CLARCC) Initiative. He serves as a Senior Fellow with the Agents of Change in Environmental Justice Fellowship and as a climate expert with the Lancet Countdown U.S. Brief Working Group. He has also served as a Climate Security Fellow with the Center for Climate & Security, Council on Strategic Risks.

His science-policy experience includes serving as a Christine Mirzayan Science and Technology Policy Fellow at the National Academy of Sciences, where he contributed to consensus studies on sexual and gender minority well-being and on rising midlife mortality and socioeconomic disparities. He also co-led an institutional DEI assessment initiative at the Academies. He is a former Robert Wood Johnson Foundation Health Policy Research Scholar, an affiliate with Harvard Innovation Labs and the Harvard Climate Entrepreneurs’ Circle, and a founding member and former Policy & Programming Director of the National Association for Doctors of Public Health (formerly the DrPH Coalition). His most recent engagement includes serving as a Social Science Fellow (Education & Workforce Development) through the Oak Ridge Institute for Science and Education (ORISE) Policy Fellowship program.

Prof. Irfan’s research centers on advancing health and social equity through a climate justice lens, focusing on how systems, technologies, and institutions can be transformed to reduce inequities and strengthen community resilience. Grounded in decolonial and equity-driven frameworks, his work examines the ways emerging technologies, sociocultural structures, and global crises shape population health—particularly for communities historically marginalized or structurally excluded.

At the core of his scholarship is a science-for-social-impact paradigm: applied, practice-anchored research designed not only to generate knowledge but to catalyze meaningful change in policy, pedagogy, and public health systems. Rather than centering publication metrics, his work prioritizes real-world implementation, organizational learning, and the development of equitable, actionable solutions. This includes co-creating interventions with communities, designing ethical and justice-aligned uses of technology in public health, and rethinking institutional practices so they better serve diverse populations.

Across these domains, his research weaves together climate justice, health equity, digital transformation, and public health systems innovation to understand—and ultimately transform—the structural conditions that shape well-being, opportunity, and justice. His scholarly and public writing has appeared in The Boston Globe, Scientific American, Environmental Research Letters, Environmental Health News, and other outlets.

Dr. Irfan’s current applied research areas:

  • AI Ethics and Public Health Systems: Explores the ethical, policy, and metaphysical implications of integrating artificial intelligence into public health infrastructure, including research, education, policy-making, and practice. His current phase focuses on AI ethics within public health education.
  • Rethinking Public Health Education in the Digital Age: Investigates how curriculum design can be reimagined using practice-based pedagogy, employability-focused frameworks, and ethical alignment with AI. This includes developing AI-smart and AI-resilient teaching strategies.
  • Climate Grief as a Social Determinant of Health: Theorizes climate grief—particularly disenfranchised grief—as a structural determinant of health. This work applies a thanatological lens to assess its implications for policy, mental health, and public health practice.
  • Religion and Public Health Frameworks: Examines how religion shapes public health governance, education, research, and policy, including how religious worldviews operate as structural determinants of health.
  • Climate Innovation, Technology, and Equity: Analyzes the social equity impacts of climate technologies, including climate entrepreneurship, innovation ecosystems, and philanthropic sector frameworks. This work includes investigating nuclear energy and carbon capture and sequestration (CCS) through an equity and organizational-learning lens.
