My background is in climate, atmospheric science and hydrology, as well as biology. I study the environmental determinants of infectious disease transmission and use mathematical modeling, data assimilation and ensemble approaches to simulate, infer critical properties, and forecast infectious diseases. More broadly I investigate how meteorology affects human health and study infectious disease transmission dynamics. I have also studied a number of climate phenomena, including Rossby wave dynamics, atmospheric jet waveguides, the coupled South Asian monsoon-ENSO system, extratropical precipitation, and tropical cyclogenesis.

Jaime Cascante Vega

Staff Scientist
Department of Environmental Health Sciences 
Mailman School of Public Health 
Columbia University
[email protected]

Jaime is Colombian and received his MSc and BSc from the Biomedical Engineering Department from Universidad de los Andes. His research interests lie in the intersection with mathematical modelling as a tool for understanding complex ecological and epidemiological phenomena and deep learning and statistical techniques as a tool for extracting hierarchical features of different data-sources and infer key parameters of the models. At Columbia University, he is working on understanding the time-space spread on antimicrobial resistant (AR) pathogens, specifically of Methicillin-resistant Staphylococcus aureus (MRSA) using mathematical models combined with inference to better prevent, control, and forecast this healthcare associated infections (HAIs). He will also help in the simulation and forecast of the spread of SARS-CoV2 at population scales.

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.

She grew up in New York City and received an MSPH in Global Disease Epidemiology and Control from Johns Hopkins University in 2019, where her research included investigating sanitation availability in northern India and mobility among female sex workers in Guinea-Bissau. She also spent a semester in Cameroon working on implementation research and programming for key populations at risk for HIV. Prior to starting her master’s program, she worked in health education, clinical research, and international non-profit settings. Emma is interested in infectious disease dynamics and, while at Columbia, hopes to apply mathematical modelling methods to issues of emerging infectious diseases.

Columbia University
[email protected]

Roselyn received her PhD in Mathematics from Botswana International University of Science & Technology. Her area of expertise is applied mathematics, with specific focus on Mathematical Epidemiology. Her doctorate was dedicated to the development and analysis of mathematical models for infectious diseases (such as Ebola virus disease and AIDS-associated Kaposi’s sarcoma) caused by viral infections, with a particular interest in gaining more insight into disease dynamics and outbreaks, leading to the control of disease spread. At Columbia University, Roselyn is working on investigating nonlinear error growth in infectious disease systems and developing model-inference frameworks for simulation of infectious agents, inference of critical epidemiological characteristics, counterfactual simulations, and projections and forecasting.

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.

Mailman School of Public Health 
Columbia University
[email protected]

Matteo earned his PhD from the Department of Biomedical and Clinical Sciences at University of Milan (Italy) and his MS in Biosciences from University of Camerino (Italy). His doctoral studies mainly focused on the development of bioinformatic tools and protocols for fast and inexpensive subspecies typing of pathogens, particularly in nosocomial settings. At Columbia, Matteo is working on metapopulation mathematical models with data assimilation methods to study and forecast the dynamics of infectious diseases. He is also working on human genomic data to perform Genome-Wide Association Studies of acute respiratory infections.

Tal Robin

Postdoctoral Research Scientist 
Department of Environmental Health Sciences

Tal received his Ph.D. from the Department of Physical Chemistry at Tel-Aviv University for his work on stochastic approaches to the analysis of kinetic schemes. His previous work included models of enzymatic reactions, adhesion, and pollination with emphasis on intuitive modeling. His main interests are stochastic processes, agent-based modeling, and statistical inference. At Columbia, Tal is working on a network-based model of antimicrobial-resistant pathogens spreading within hospitals in an effort to extract accurate estimations of model parameters and identifying individuals with increased risk. This work’s aim is to advance knowledge about specific infections as well as the methods themselves.

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.
