Tristana Perez

Head of Impact

Tristana Perez has worked in global public health for almost ten years and has specialist expertise in the research and evaluation of public health interventions and programmes to drive progress on health challenges in low- and middle-income countries.

Tristana is Head of Impact and is responsible for the impact analyses across MedAccess’ agreements portfolio. She applies impact estimate methodologies to every part of the agreement process, from identification of opportunities and their potential impact through to the execution of the agreement and beyond, ensuring that there are robust and tangible measures of impact for each product that is supported through a MedAccess agreement.

Tristana owns the organisation’s Impact Framework, ensuring that it is frequently reviewed and strengthened as the portfolio grows and more products are delivered in priority markets. Her work has included the development and launch of new aggregate impact indicators to understand the full breadth of impact across the portfolio, and new measures to continually monitor sustained impact after the initial terms of an agreement are completed.

The process of evaluating the impact of market shaping activity in global public health is critically important and in a relatively nascent stage in the public health field. Bringing experience in scientific research and working closely with academic partners, Tristana is leading MedAccess’ approach to impact evaluation, ensuring that every agreement is assessed on its fundamental impact for people, for governments, and for the partners involved.

Prior to MedAccess, Tristana worked first at Wellcome Trust as a Grants Advisor in population health research, exposing her to a broad range of research proposals and exploratory approaches to public health challenges. Moving on to Public Health England (PHE), Tristana worked in the global health strategy team, responsible for the facilitation of knowledge exchange between PHE and technical experts addressing health needs in lower income countries, and later deployed to support the PHE response during the COVID-19 pandemic.

Tristana holds a degree in Molecular Biology from Princeton University, US, and a Master’s in Public Health with a focus on global health from Imperial College London. She has undertaken research roles in a number of academic institutions including Boston University School of Medicine, US, and Oxford University Clinical Research Unit, Nepal. Throughout her career Tristana has taken opportunities to develop her specialism and she is currently undertaking a doctorate in public health at the London School of Hygiene and Tropical Medicine.
