Daniel Carrion, PhD'19

Postdoctoral Fellow
Environmental Medicine & Public Health
Mount Sinai

Daniel Carrión completed his PhD in Environmental Health Sciences in the Climate and Health Program in July 2019. His doctoral thesis examined the impact of household air pollution on upper respiratory microbial carriage of infants, as well the socioecological determinants of biomass combustion amongst families in rural Ghana. He is now a Postdoctoral Fellow in the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai. In his current role, he is working in Dr. Allan Just’s research group to refine large-scale exposure models of temperature and air pollution using remotely sensed data, and conducting epidemiological analyses with those exposure datasets. He received a BA from Ithaca College and an MPH from New York Medical College.

Carlos Gould, PhD'21

Postdoctoral Research Fellow
Stanford Earth

Carlos Gould completed his PhD in Environmental Health Sciences in the Climate and Health Program in July 2021. His thesis, titled “As the smoke clears: assessing the air pollution and health benefits of a nationwide transition to clean cooking fuels in Ecuador,” studies the impact of Ecuador’s nationwide transition from biomass to gas cooking, facilitated by long-standing subsidies, on air pollution exposure and children’s health. Weaving together tailored energy access surveys, state-of-the-science sensors, and administrative data, he shows that despite cheap and accessible cooking gas, a large portion of Ecuadorian households still use biomass for some of their daily cooking and heating needs, leading to air pollution exposure above health-based guidelines. Nonetheless, Carlos’s research shows that Ecuador’s investments in cooking gas subsidies over the last three decades have facilitated reductions in lower respiratory infection mortality among children under 5 years. Throughout his time at Columbia, Carlos built a research agenda focused on the potential for household energy transitions to address climate change and improve health by reducing air pollution exposure. In particular, he studied the adoption and use of cooking gas in India and evaluated the impacts of clean cooking interventions on air pollution exposure and health in Ghana. Carlos is now a Stanford Earth Postdoctoral Fellow where he investigates (1) the impacts of India’s ongoing clean cooking transition on air quality, health, and climate and (2) the health and climate benefits of clean-to-cleaner fuel transitions (e.g., from gas to renewable-based electricity).

Postdoctoral Research Scientist
Department of Environmental Health Sciences
Mailman School of Public Health

Her thesis, “Quantifying the effect of extreme and seasonal floods on waterborne disease in the US,” examined the association between flooding and 10 waterborne pathogens with a particular focus on Legionnaires' disease. A primary component of this work was to characterize the different flood types that occur throughout the US (e.g. floods related to cyclonic storms, river floods, flash floods, etc.) by using a range of meteorological variables to define flooding. Her work found that hospitalizations for specific pathogens were positively associated with distinct flood-indicator variables. She also studied the effect of tropical cyclonic storms on cases of waterborne diseases in the Eastern US.

He also constructed a nationwide, uncertainty-aware model of annual fine particulate concentrations that leveraged the unique strengths of already-developed models, and examined the distribution of predictive uncertainty to inform future monitoring efforts.  

Israel Ukawuba, PhD'21

Florence Levy Kay Postdoctoral Fellow
Brandeis University

Israel Ukawuba completed his PhD in Environmental Health Sciences in the Climate and Health Program in July 2021. His thesis work, "Use of climate in a simple entomological framework to improve dynamic simulation and forecast of malaria transmission" developed a parsimonious, dynamical model for malaria transmission, with direct climate modulation of the ecology of the malaria parasite and vector. He identified important ecological pathways by which climate drives local transmission and used this climate-based model to explain malaria variability over several seasons across local communities in sub-Saharan Africa. He also developed a novel dynamical forecasting system for malaria incidence based on the climate-driven model and a highly promising forecasting framework. With this system, he generated real-time forecast of malaria incidence for 42 communities and 5 regions in a malaria endemic country. Israel is now a postdoc at the Heller School, Brandeis University, where he will be teaching and researching infectious disease epidemiology.
