My interest is to combine research with public health practice in the fields of health systems and community- and technology-savvy approaches to improving maternal, neonatal and child health, with particular work experience in the U.S., the Philippines, Kenya and Tanzania.

My focus is to test new platforms to scale up vaccine access, to determine best practices for scaling up vaccine access in unstable health systems, to make the economic case with and for countries to invest in preventive medicine strategies such as equitable, sustainable vaccine access programs, and to define methodological, research-based frameworks for community-based health systems strengthening interventions, focused on maternal, neonatal and child health.
