Postdoctoral Research Scientist
mg3822@cumc.columbia.edu

Marta Galanti completed her PhD research in Complex Systems and Mathematical Physics in a shared program between University of Florence (Italy) and University of Orléans (France). Her previous research focused on the analysis of diffusion-reaction processes in biological and industrial media in non-ideal conditions (complex geometries and crowded environments). At Columbia, she is working on developing mathematical models to generate predictions and advance the understanding and forecast of infections.  One of the goal of her research will be to study respiratory virus transmission with the aim of incorporating antigenic information of rapidly evolving viruses into real-time forecasts of influenza.

Abhishek obtained his doctorate in Resources, Environment and Sustainability from the University of British Columbia. He received his MBA from Indian Institute of Forest Management after completing BSc in Physics from Calcutta University. He was previously a Research Fellow at the Energy and Resources Institute (TERI), an Indian think-tank. He is currently an ISEP (Initiative for Sustainable Energy Policy) Fellow at Johns Hopkins School of Advanced International Studies and was selected in the 2018 Young Scientists Summer Program at the International Institute for Applied Systems Analysis (IIASA). Over the last twelve years, his multi-disciplinary research experience spans aerosols, human behavior, and policy analysis related to household air pollution in specific and energy access in general. His doctoral dissertation entailed application of classical behavior change theories in conjunction with large consumer behavior datasets to better understand clean cooking energy transitions. His research findings have been shared widely on social media, including by the Prime Minister of India, and covered at the front page of major Indian newspapers. He has embarked upon the journey of writing a book on India’s Ujjwala program to promote cooking gas. At Columbia, Abhishek is working with Dr. Darby Jack on a clean cooking intervention project in Ghana. His current research efforts involve application of eddy covariance method to measure pollution levels at community scale and using epidemiological data to assess the health impact of local cooking practices.

Yanelli Nunez earned her PhD in Environmental Health Science at Columbia University and her BS in Biology with a focus on neuroscience and a minor in Public Health from San Diego State University. She is an environmental epidemiologist and her primary research interest is on understating the adverse effects air pollution has on the nervous system. She is also interested in mixture methods and their incorporation into environmental epidemiology. Her doctoral research examined the association between exposure to fine particulate matter and particle components with clinical disease aggravation of neurodegenerative diseases. As a fellow in the Climate and Health program, she is working on identifying sources of air pollution mixtures and the association of such sources with adverse neurological outcomes using novel pattern recognition methods.

Georgette Owusu-Amankwah, PhD

Postdoctoral Research Scientist
go2285@cumc.columbia.edu

Georgette holds a doctoral degree in Agricultural Economics from the University of Kentucky. Her research interest is primarily in Development and Health Economics. Her doctoral research examined constraints that have hindered the ‘buy-local’ policy mandate of the Ghana School Lunch program, and explored gendered agricultural technology adoption and contract participation strategies that could facilitate the policy mandate. Georgette’s current research with Drs. Darby and Kelsey Jack examines viable clean energy sources, household adoption and use decisions, and the health impacts of cleaner fuels in Ghana, with interventions to support community-level adoption and sustained use of clean household energy technologies.

Robbie Parks, phd

Postdoctoral Research Fellow
rmp2198@columbia.edu

Robbie earned his PhD from Imperial College London and an undergraduate degree in physics from the University of Oxford. He is an environmental epidemiologist whose primary interests are in understanding the impact that climate, weather, and air pollution has on mortality, nutrition, and disease outcomes, and how these impacts may be different in sub-groups of a population. He is also interested in developing new (particularly Bayesian) statistical methods, relevant to these concerns. In summer 2017, during his studies, he interned at the World Meteorological Organisation, a constituent part of the United Nations, in Geneva, Switzerland. While interning, he became a founding member of the Global Heat Health Information Network.
