Lab members Susan Tsui & Darwin Keung in the field to deploy light sensors for our NIEHS funded pilot study “Characterizing the Modern Light Environment and its Influence on Circadian Rhythms”
earned her PhD in Ecology and Evolutionary Biology at Princeton University. Her research focuses on the ecology and immunology of infectious and inflammatory diseases. She has a particular interest in understanding how variation in within-host immune processes contributes to heterogeneity in disease susceptibility. As a postdoc in the Martinez lab, Jacqueline is characterizing seasonal and circadian rhythms in the human immune system to determine whether functional changes in immune responses occur throughout the year that may impact susceptibility to disease.

Tigidankay (TK) Saccoh
is currently a junior at Columbia College majoring in psychology and concentrating in public health. She has been working in the Martinez Lab since the Spring 2019 semester. Currently, using the R program and existing scientific literature, she is working on a paper that explores the best measles vaccination schedules for children. She hopes to resume her study of how maternal immunity is implicated in the development of the infant immune system once it is again safe to work with human participants. TK is especially interested in reproductive justice and improving health outcomes for mothers and infants in the developing world. She plans to pursue a joint JD/MPH degree after she graduates and ultimately hopes to improve reproductive health for women in Sierra Leone, where she was born. Outside of academics, she loves to cook and watch psychological thriller movies. (firstname.lastname@example.org).
is currently a Junior at the Macaulay Honors College at Hunter majoring in Arabic Language and Culture. Starting in the summer of 2020, she worked with Dr. Martinez on digitizing and analyzing data from the NYC Department of Health on the disparities of the COVID-19 public health crisis. As an aspiring physician, she hopes to combine her interests in science with her passion for patient advocacy in her research projects. She was accepted into the FlexMed program and thereby will be attending the Icahn School of Medicine at Mount Sinai following her undergraduate studies.
earned his Master of Public Health in Environmental Health Sciences at Columbia University Mailman School of Public Health. His research interests revolve around working with complex datasets to improve understanding of environmental exposures and improve population health. Dennis works with Dr. Martinez to characterize seasonal variation in daily light exposure among residents of the New York City area, and identify associations between differential exposure to light at night and circadian biology.

is a PhD student in Environmental Health Sciences at Columbia. Before starting at Columbia, she completed her MSPH in Global Disease Epidemiology and Control at Johns Hopkins University in 2019, where her research included investigating sanitation availability in northern India and mobility among female sex workers in Guinea-Bissau. Prior to her master’s program, she worked in health education, clinical research, and international non-profit settings. Emma is currently working with Dr. Martinez on using traffic data to model population mobility at the beginning of the COVID-19 outbreak in NYC.
earned her PhD in Ecology and Evolutionary Biology at the University of Michigan. There, she developed crickets as a model system to research the mechanisms and consequences of inherited nongenetic effects, particularly those resulting from dietary stress and social conditions. Now a fellow in the Climate and Health Program, she is working to identify effects of food insecurity and parental stress on the descendants of the stressed individuals. Katherine’s current work combines computational epigenetics (using human-generated data) with laboratory studies on vertebrate and invertebrate species. The central goal of her work is to identify environmental risk factors that can have disproportionately negative future effects, which in turn can be used to inform public health policy and approaches.

is a Master of Public Health candidate in Epidemiology at Columbia University Mailman School of Public Health. Her interests lie in social epidemiology and health equity. Susan currently works with Dr. Martinez to study the impact of light pollution on circadian rhythms in residents of Northern Manhattan and the Bronx. She earned a B.A. in biology from Boston University where she also conducted undergraduate research on mycorrhizal fungi. Prior to working with Dr. Martinez, she completed a year of service with AmeriCorps in East Harlem, New York City. (
received his BA in Sociology from Princeton University and is the Martinez Lab Manager and Research Associate. He is interested in the transmission dynamics and control of infectious diseases, as well as the implementation of cutting-edge epidemiological/statistical modeling in the analysis of big data for use in population health management. His previous research has focused on measuring the impact of migration on varicella (i.e., chickenpox) transmission along the U.S.-Mexico border and analyzing the relationship between changing infant vaccination and breastfeeding rates and the incidence of flu-related hospitalizations among children in the United States. He is currently working on building a dynamic transmission model to estimate the efficacy of the varicella vaccine.
Darwin Keung is a Master of Public Health candidate in Environmental Health Sciences at Columbia. He previously studied C. elegans innate immunity and murine blood stem cell differentiation while completing his bachelor’s thesis at Haverford College. Darwin is interested in environmental health challenges that arise from modernization and urbanization. Currently he is investigating the effects of light pollution and artificial lighting on circadian rhythms.
is a senior at Princeton University. Over the past three years of working with Dr. Martinez, Daniel has conducted research on rubella serology and circadian biology. He is currently completing his thesis on the within host dynamics of African Sleeping Sickness and the relationship between circadian rhythms in the host and parasite dynamics.

was a member of the Martinez Lab for three years. Her primary research was focused on maternal immunity and early vaccination against measles. In 2018, she defended her thesis “Reassessing the Measles and Rubella Vaccination Schedule” and received her BS in Ecology and Evolutionary Biology at Princeton. Aria also worked on polio vaccine efficacy and contributed to forthcoming work on OPV efficacy. Aria is now a postbaccalaureate trainee at University of Rochester.
is a senior at Princeton University. Annalise assisted with research on polio vaccination while working with Dr. Martinez in 2016 and 2017.
– As an undergrad summer research student, Busola worked with Dr. Martinez at the University of Michigan studying polio outbreaks. She is now a Biomedical engineering Ph.D. candidate at the University of Texas Southwestern Medical Center, working on creating ex-vivo 3D models to study colorectal cancer. Busola “hopes to be part of the next generation of scientific researchers that are helping to bridge the gap between science and engineering in order to find more effective solutions to diseases. Outside of academic work, I like taking long walks, dancing salsa and trying out new cooking recipes.”
worked with Dr. Martinez as an undergraduate summer research student at the University of Michigan. She is now a graduate student at Wayne State University studying Biomedical Instrumentation. Emi has “an aspiration to work with underserved populations. After working on the seasonality of Alzheimer’s disease with Micaela Martinez, I was fortunate enough to experience conducting research abroad thanks to her strong recommendation.”
