Abigail Greenleaf

Abigail Greenleaf serves as Assistant Professor in the Department of Population and Family Health at Columbia University's Mailman School of Public Health, where she is also an affiliated member of the Health Analytics Center and collaborates with ICAP's Population-Based HIV Impact Assessment (PHIA) project under national ministries of health.

Her academic credentials include:

• MPH from Columbia University
• PhD in Population, Family and Reproductive Health from Johns Hopkins Bloomberg School of Public Health

As a public health demographer, Dr. Greenleaf pioneers mobile phone-based data collection methodologies in resource-limited settings where traditional survey approaches face challenges. Her research rigorously evaluates the reliability of phone surveys in African contexts where cell phone penetration has recently reached viable thresholds, enabling efficient HIV epidemic benchmarking through PHIA and rapid adaptation to real-time coronavirus symptom surveillance during the pandemic. This work directly informs targeted public health policies through cost-effective, high-quality data generation.

Her professional recognition includes:

• Allan Rosenfield Global Health Fellowship

Dr. Greenleaf actively mentors students through co-teaching "Research Design and Data Collection" for graduate students and "Data Science and Health Equity in New York City" for undergraduates, where she translates her Cameroon Peace Corps experience and CDC fellowship background into practical data science applications for urban health disparities. Her PHIA project leadership demonstrates significant grant-funded research capacity, though specific grant details aren't elaborated in the source material.

She operates within Columbia's ICAP consortium framework, collaborating with national health ministries across multiple countries to transform survey infrastructure into actionable public health intelligence, particularly evidenced by her rapid mobilization of PHIA resources for pandemic response in Lesotho.
