My background is in climate, atmospheric science and hydrology, as well as biology. I study the environmental determinants of infectious disease transmission. In particular, I investigate how atmospheric conditions impact the survival, transmission and seasonality of pathogens and how hydrologic variability affects mosquito ecology and mosquito-borne disease transmission. More broadly I am interested in how meteorology affects human health. I am now working to develop systems to forecast infectious disease outbreaks at a range of time scales. In addition, I study a number of climate phenomena, including Rossby wave dynamics, atmospheric jet waveguides, the coupled South Asian monsoon-ENSO system, extratropical precipitation, and tropical cyclogenesis.

Post-Doctoral Research Scientist
Department of Environmental Health Sciences 
Mailman School of Public Health 
Columbia University
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 goals 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.

sck2165@cumc.columbia.edu

Sarah Kramer received her bachelor’s degree in Biology of Global Health from Georgetown University in 2014.  She then worked for one year as a Fulbright scholar at the Robert Koch Institute in Berlin Germany. Previous projects have included the use of contact network models to assess influenza control measures, and the use of statistical models to assess determinants of HIV risk behavior. As a Columbia student, Sarah hopes to expand on her previous experience by considering the role that the environment plays in the spread of infectious diseases.

Columbia University
sal2222@cumc.columbia.edu

Stephen began his PhD in the fall of 2017. Originally from Ohio, he received a BS in Environmental Science from the United States Military Academy in 2002 and a commission in the U.S. Army as a Medical Service Corps officer. In 2011, he completed a Master’s degree in Environmental Health at Harvard School of Public Health with an emphasis on exposure science, epidemiology, and risk assessment. At Columbia, Stephen is interested in assessing environmental hazards that impact human health, focusing on urban populations and exposures encountered during military service.

Columbia University
vdl2103@cumc.columbia.edu

Tory received her MPH in epidemiology of microbial disease from the Yale School of Public Health and her bachelor’s in environmental biology from Georgetown University. Her master’s research focused on the association between seasonal climatic factors and typhoid fever. At Mailman, she hopes to study how extreme climatic events influence the spread of water-borne infectious diseases.

Haruka Morita received her MPH from the Mailman School of Public Health and her BS in Biology from Lehigh University. She is interested in health impacts of various climate change events, and her most recent work includes a health impact assessment on cardiopulmonary outcomes due global PM2.5 pollution from the aviation sector (manuscript submitted). With Dr. Shaman, she is currently working on a project studying influenza and other cold virus viability in NYC subways, as well as a health assessment on indoor temperature and humidity conditions in NYC apartments.

Sen Pei received his PhD degree in Mathematics from Beihang University (Beijing University of Aeronautics and Astronautics) in Beijing, China. His previous research focused on the modeling and empirical study of spreading dynamics in social networks, including information propagation and outbreaks of infectious diseases. At Columbia, he is  examining the predictability of the nonlinear dynamics of influenza spreading and developing skillful ensemble-based prediction systems for infectious diseases.

Columbia University
dns2142@cumc.columbia.edu

Dona received her M.D. in General Medicine from Nizhny Novgorod State Medical Academy in Russia. She was a practicing physician in anesthesiology/ intensive care and ER for the last ten years and she did her post graduate studies in anesthesiology in Sri Lanka. During her work in the ICU she engaged in hospital-based research in infectious diseases in dengue hemorrhagic fever and leptospirosis and studied the severity of clinical outcomes associated with patient admission time to the hospital . She earned ECFMG certification after completing United States Medical Licensing Exams. With Dr. Shaman, Dona is currently working on a project studying symptom response to respiratory viral infections.

Teresa completed her PhD in hydrology at MIT in the department of Civil and Environmental Engineering. Her research interests lie at the intersection of environment and infectious disease, with a focus on vector-borne disease.  Her doctoral research explored the relationships between climate, entomology, and malaria transmission in West Africa using a framework of detailed mechanistic modeling.  This framework was used to assess the impacts of climate change on malaria transmission.  At Columbia, she is developing transmission models for dengue and other vector-borne diseases to be used in conjunction with data assimilation methods to generate ensemble-based forecasts of disease outbreaks.
