Dr. Marina Treskova

Marina is a junior group leader. She has completed her PhD in Health Economics, where she focused on the model-based evaluation of public health interventions such as vaccination and cancer screening. She has also been trained in Biology and Epidemiology. Her current research interest and focus lie on the impacts of changing climate on infectious diseases such as vector-borne and zoonotic diseases. She is particularly interested in investigating climate change and land use effects on zoonotic pathogen spillover from reservoir host animals to humans and domestic animals. Further, her domain includes interventions that go beyond conventional public health and target disease emergence at the source. These include upstream prevention policies, mosquito-bite control, and nature-based solutions. In her research, she utilizes different models and methods of intervention science to explore effective and cost-effective ways to prevent the emergence and re-emergence of infectious diseases.

Dr. Connie Hoe

Connie is an Alexander von Humboldt Research Fellow and Research Group Leader at Heidelberg Institute of Global Health, Heidelberg University. She is also an Assistant Professor at Johns Hopkins Bloomberg School of Public Health, International Health Department (currently on leave of absence). Her research focuses on the politics of health policymaking in low-and middle-income countries; specifically, she utilizes social science theories and methods to explore the process and determinants that lead to public health policy adoption, implementation, and compliance. This, for example, includes understanding the role of evidence in decision-making, and the role of interest groups (e.g. corporate actors) as well as other actors in the policymaking process. Connie has led an array of international health projects in Africa, Asia, and Eastern Europe. As a consultant, she has advised the World Health Organization and the Asian Development Bank. Connie has also had the opportunity to serve as expert reviewer for the World Health Organization, expert for the Implementation Hub, International Union Against Tuberculosis and Lung Diseases, and expert for the Commonwealth Road Safety Initiative. Connie received her PhD in Health Systems from Johns Hopkins Bloomberg School of Public Health, MSW from the University of Pennsylvania, School of Social Policy & Practice, and BA from Johns Hopkins University.

Dr. Aditi Bunker

Aditi’s research tests climate change adaptation and mitigation interventions to assess how they affect population health, environmental and economic outcomes. Using experimental and quasi-experimental designs, she conducts large-scale causal impact evaluations on interventions in the housing, urban design, infrastructure and food sectors to identify how they affect outcomes, including infectious disease. She uses novel approaches to co-design technology based solutions for populations including growth hacking, citizen science approaches and hackathons. Aditi leads a work package on evaluating local interventions for resilience to zoonotic disease in the Horizon Europe funded project Infectious disease decision-support tools and alert systems to build climate resilience to emerging health threats (IDAlert). Here, her research tests the effectiveness of nature based solutions, citizen science tools and urban design changes (i.e., mosquito-proof drain infrastructure changes in Barcelona together with local government) on infectious disease outcomes. Knowledge generated through Aditi’s research will inform governments, citizens, private sector and donors on uptake of adaptation and mitigation interventions with co-benefits for health, environment and the economy. Aditi enjoys developing public-private partnerships and working with government to scale and enable technology transfer of proven interventions to climate-vulnerable communities. Aditi is the recipient of multiple Horizon Europe grants and a German Science Foundation (DFG) grant. She leads a climate change intervention work programme at Heidelberg University, and is a visiting scientist at Harvard Chan C-CHANGE.
