Jackie Leung is broadly interested in the ecology, immunology, and epidemiology of infectious diseases. She has a particular interest in understanding why hosts are so heterogeneous in their immune responses to infection. Her dissertation research examined ecological interactions between helminths and microbes in the vertebrate gut and the consequences these interactions have for host health and disease. Specifically, she performed re-wilding experiments in mice to investigate how the external environment shapes helminth susceptibility via changes to host immunity and the gut microbiota. She also conducted a clinical study in humans to determine how helminth removal via deworming impacts enteric infections and the wider intestinal ecosystem. As a postdoc in the Martinez lab, Jackie will characterize 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).
Salwa Najmi 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.
Dennis Khodasevich 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.

Emma Gorin 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.
