Team

Debattama (Deb) Sen, PhD is a Principal Investigator in the Massachusetts General Hospital Center for Cancer Research and a faculty member at Harvard Medical School. She received her B.S. from Columbia University in Biomedical Engineering & Computer Science before training with Nick Haining at the Dana-Farber Cancer Institute. Her principal research focus has been understanding the regulatory pathways that drive immune dysfunction in chronic viral infection and tumors, as well as exploring strategies to reverse these changes. Outside the lab, she attempts to recreate Great British Bake Off recipes and enjoys falling down mountains in a controlled manner (aka skiing).

Richard Davidson joined the Sen lab in November 2020 as a technician, after completing his graduate degree at Boston University. He had previously worked at Pfizer studying neurological inflammation in cases of Parkinson’s and Alzheimer’s diseases through rodent models. Now investigating the process of T cell exhaustion at the Sen lab, Richard develops in vitro models in addition to providing support for collaborative projects between Sen & Sharpe labs. Richard enjoys trying new boardgames, will one day perfect his meatloaf recipe, and can usually be found taking midnight walks about Brighton.

Chang-Yu (Alex) Chen joined the Sen lab in 2021 as a postdoctoral fellow. He received his B.S/M.S. in Medical Laboratory Science and Biotechnology from Taipei Medical University, where he discovered his passion for cancer immunology in Dr. Chien-Ho Chen’s Lab. He then went on to receive his Ph.D. at The University of Tokyo, working in the lab of Dr. Kouji Matsushima, studying the combination strategies (HMGN1 + CD4 depletion/PD-L1 blockade) to reverse T cell exhaustion and improve T cell-based therapy. In the Sen lab, Alex focuses on deciphering T cell epigenetic imprinting to understand how specific tumor environments shape T cell exhaustion/dysfunction. Outside the lab, Alex enjoys running, cooking, and traveling.

Sarah Weiss is a MD/PhD graduate student leading the joint Sen/Sharpe lab enhancer-deleted mouse project. During undergrad, she majored in Biological Engineering at MIT and worked in the Wilson lab studying memory consolidation during sleep by modulating hippocampal activity with engineered ion channels. In the Sharpe lab, she will be pursuing projects related to genetic recording in cancer cells and T cells. When Sarah is not in lab, she enjoys running and biking outside, baking and eating sweets, and giving her doggie Luna all the belly rubs.

Lab Alumni

Sydney Loh is an undergraduate at the University of Pennsylvania studying physics with a minor in architecture. In her free time she loves to go on hikes, do ceramics, and climb with friends. As a research assistant in the lab, she performed single-cell RNA-sequencing data analysis of exhausted T cells in chronic infection.
