Alex Samura-Ernst

Technical Director, San Francisco Contact Tracing Program

Alex Ernst provides broad technical oversight, from day-to-day contact tracing workflow to materials development and quality-improvement activities to data analysis and reporting. Pre-COVID-19, she worked primarily on HIV M&E and epidemiology projects, specifically recent HIV infection surveillance worldwide. Upon completing her MPH at Tulane University, Alex served as a health sector Peace Corps Volunteer in Mozambique, which gave her extensive cultural context and first-hand experience working with partners and local health authorities to implement new health-service delivery programs. Alex’s dedication to this work stems from a health equity lens: making sure that our most vulnerable, most marginalized, and most impacted populations are being heard, treated with dignity and respect, and that their health needs are met in a high-quality and empathetic manner.
