Randy Longman, MD / PhD, Principal Investigator

Randy is a gastroenterologist and mucosal immunologist focused on inflammatory bowel disease (IBD) research.  He completed his undergraduate studies at Yale University and his graduate work at the Tri-Institutional (Rockefeller/Sloan-Kettering/Cornell) MD-PhD Program.  Randy did clinical Internal Medicine and Gastroenterology training at Columbia University Medical Center and post-doctoral training with Dr. Dan Littman at NYU.  The intricate dialogue between host and pathogen fascinates him; his research aims to discover novel mechanisms of microbial regulation of mucosal and systemic immunity and to develop new, targeted therapies for IBD. Outside of science, Randy loves spending time with his family, skiing, and playing soccer! 


Lance Chou, Lab Manager / Research Technician

Despite spending almost all of his life in the San Francisco Bay Area, Lance moved across the country to join this lab, shortly after obtaining his undergraduate degree in Chemical Biology from UC Berkeley. While there, he spent a few years in a neuroscience lab studying the sleep and wake cycle in mice. He hopes to pursue a career in biomedical research and plans to apply to graduate school in 2019. Outside of lab, you can find Lance in the climbing gym or at home watching Netflix.

Monica Viladomiu, PhD, Postdoctoral Associate in Medicine

Monica grew up in Barcelona (Spain), where she earned her undergraduate degree in Biotechnology. After college, she joined the Genetics, Bioinformatics and Computational Biology program at Virginia Tech. Her doctoral work combined experimental immunology and high-throughput sequencing approaches to characterize the mechanisms by which mononuclear phagocytes contribute to chronic Helicobacter pylori persistence and differentially modulate adaptive immune responses, thus affecting disease outcome.  After receiving her Ph.D., she joined the Longman Lab as a post-doctoral associate. Trained as an immunologist, Monica is interested in microbial regulation of intestinal and systemic immune responses, with the ultimate goal to understand the underlying pathogenesis of inflammatory bowel diseases and develop new therapies to improve health outcomes.


Svetlana Lima, DVM, PhD, Postdoctoral Associate in Medicine

Svetlana grew up in Goiânia (Brazil) where she earned her Doctor of Veterinary Medicine from Federal University of Goiás. After obtaining her DVM degree, Svetlana came to New York and pursued her PhD in Animal Science (minors in Microbiology and Epidemiology) from Cornell University, where she combined microbiome research, molecular biology and population studies to develop strategies that prevent and/or moderate animal diseases. Currently, Svetlana is interested in host-microbiome interaction, gut-drug microbe interaction and mucosal immunology.


Maeva Metz, PhD Student

Maeva grew up in Connecticut where she first became interested in microbes. She went on to pursue a B.S. in Microbiology at Miami University in Ohio minoring in Molecular Biology. There she conducted research on the multidrug-resistant pathogen, Acinetobacter baumannii, under the mentorship of Dr. Luis Actis, using molecular genetics to identify and characterize targets for antimicrobial therapeutics. Wanting to expand her knowledge of host-microbial interactions and mucosal immunology, she spent a summer conducting research in Dr. Wendy Garrett’s lab at Harvard Medical School investigating the role of the commensal Fusobacterium nucleatum in tumorigenesis of colorectal cancer. She is currently at Weill Cornell Medical College pursuing a Ph.D. in Immunology and Microbial Pathogenesis and is interested in investigating the mechanisms by which human derived commensal bacteria modulate the mucosal and systemic immune systems both at steady state and under acute or chronic inflammation. When she is not in lab, Maeva loves being outdoors hiking or you will find her at the local animal shelter playing with puppies!


Lasha Gogokhia, MD, Postdoctoral Associate in Medicine

After getting his graduate degree from Tbilisi State Medical University (Georgia), Lasha worked with bacteriophages at the University of Utah before coming to New York and joining the Longman Lab.
