Marcus Clark
Principal Investigator

Margaret Veselits
Lab Manager
Margaret has been involved in studying the signaling and trafficking of the B cell receptor. She is currently working on identifying the different populations of immune cells present in biopsies of kidneys from Lupus Nephritis patients. Outside of the lab, she enjoys spending time with family & friends, trying her hand at new recipes, traveling and doing agility with her dog.

Malay Mandal
Research Professor
Malay has a number of scientific interests, including understanding the mechanism of Immunoglobulin gene reaarngement, how bone marrow extracellular cues coordinate with intracellular signaling during early B lymphopoiesis, and how molecular effectors in shaping B cell mediated humoral immune response. Additionally, Malay is interested in understanding the molecular pathways of CD4 vs CD8 lineage commitment during T lymphopoiesis.

Junting (Lily) Ai
Technologist
Ph.D.- University of Kentucky
B.S.- Southern Medical University, China
Lily is interested in studying the in situ inflammation of various tissue in inflammatory diseases by immunostaining and imaging, especially interested in immune cell interaction in situ. Outside of the lab, she enjoys cooking, yoga and playing piano.

Arunava Nag
Postdoctoral Fellow
Ph.D. – University of Nevada, Reno
Arunava is interested in developing algorithms for analyzing lupus nephritis by examining kidney biopsies and mapping these imaging-based patterns to mouse models.

Greer Gurewitz
Graduate Student - Genetics, Genomics and System Biology
B.A. – Washington University in St. Louis, 2019
Greer is interested in the intersection of genetics and immunology, specifically in understanding the epigenetics that underlie healthy progression through the DP stage of thymocyte development. In her free time, she enjoys tutoring students in writing, cooking, and biking along the lakeshore.

Thao Cao
Graduate Student - Molecular Engineering
B.S. – Washington University in St. Louis, 2020
Thao is interested in understanding tissue inflammation and fibrosis in lupus nephritis by examining multiple molecular, cellular, and structural features of the patients’ kidney biopsies and correlating these imaging-based patterns to clinical outcomes. In her free time, she enjoys baking (along with spontaneous recipe developing) and rock climbing.

Jasmine Shum
Graduate Student - Cell and Molecular Biology
B.S. – Brown University, 2024
Jasmine is generally interested in the mechanisms of transcriptional regulation and chromatin topology that drive B cell development. Outside of the lab, she enjoys reading, thrifting, and running on the lakefront trail.

Zachary Thompson
Graduate Student – Immunology
B.S. – Biomedical Engineering, Boston University, 2018
Zach is broadly interested in elucidating the molecular underpinnings of peripheral B cell tolerance mechanisms to clarify their ontology. In their free time, Zach enjoys reading, going to museums, and exploring Chicago with friends.

Sarah Kim
Research Technician
B.A. – University of Chicago, 2023
Sarah is currently researching protein interaction and complex formation in tonsillar immune cells, in support of a collaborative spatial transcriptomics research effort between the labs of Dr. Marcus Clark and Dr. Savas Tay. She is also pursuing her master’s degree in Molecular Engineering at the University of Chicago. In her free time, she enjoys rugby, chess, and fiber arts.

CJ Eichenlaub
Research Assistant
B.S. – Saint Louis University, 2025
CJ is interested in the molecular mechanisms underlying the adaptive humoral immune response, particularly the dynamics of the germinal center reaction which, if dysregulated, can lead to cancer or autoimmune disease. Outside of the lab, he enjoys exploring the city, finding new coffee shops, reading, and non-profit work.

Shelley Fernando
Undergraduate Research Assistant
Class of 2027
Shelley is interested broadly in the molecular mechanisms of dynamic genome regulation. She is also interested in how these mechanisms direct B cell development. Outside of the lab, she likes to knit and explore used bookstores.
