I study how populations change, and what that means for the people living through it. Demography is not just data. It is the story of who gets born, who survives, and who gets counted.
I'm a demographer. That means I study how populations change—who is being born, who is dying, who is moving, and what all of it means for the societies living through these shifts. I've spent twenty years turning that research into policy that actually reaches people.
For eight years at USAID, I served as the Agency's chief demographic expert, providing oversight for studies and surveys in USAID-assisted countries and shaping policy on family planning, reproductive health, migration, and global health.
These days, I split my time between research, writing, and advising. At the Carnegie Endowment for International Peace, I am leading a new initiative on India's "unfinished" demographic dividend, examining how structural constraints limit the country's potential. At the Population Reference Bureau, I write on emerging frontiers in the study of fertility, mortality, and migration, and help shape demographic communication. At the William H. Gates Sr. Institute at Johns Hopkins, I am helping create a strategy to ensure governments and policymakers design programs with demographic futures at the forefront. And I have been invited by the G7 Presidency to join the Gender Equality Advisory Council to advise on demographic issues and the global challenges they represent.
I also write a Substack called Demography Matters, where I try to make the case, one country at a time, that population data is not an abstraction. It is the foundation of every policy decision that touches a human life.
I write about the places where demographic data meets real life: low fertility panic, the politics of counting, and why the numbers we collect shape who gets resources and who doesn't.
I'm writing my way through the world, one country at a time, exploring what demography tells us about how societies function, who they leave behind, and what comes next. Each piece pairs a country with a core demographic concept. Here are the most recent.




If you're working on something where demography matters—and it almost always does—let's talk.
