Xiaolei Su, PhD

Principal Investigator

Dr. Xiaolei Su obtained his B.S. at Peking University, Ph.D. at Harvard University, and postdoc training at UCSF. As a faculty at Yale, Dr. Su leads a team studying membrane signaling in immune responses.


Kendra Libby

Research Assistant

Kendra Libby is a senior at Yale College majoring in Molecular Biochemistry and Biophysics. Prior to joining the Su Lab, she had research experience as an intern with Yale's Discovery to Cure High School Internship Program. In the Su lab, Kendra studies chimeric antigen receptor (CAR) with the goal of improving CAR localization and signaling while developing a greater understanding of how CAR triggers T cell activation. Outside of the lab, she dances competitively with the Yale Ballroom Dance Team and works with horses.


Longhui Zeng, PhD

Postdoctoral Fellow

Longhui obtained a Ph.D. in biology from Shanghai Jiao Tong University in 2018. He is currently supported by the Cancer Research Institute Irvington Postdoc Fellowship. Longhui studies how phase separation affects T cell activation and the molecular mechanism of leukemia-associated mutations of the key components such as PLCγ1 that drive T cell microcluster formation. Longhui also enjoys positive and powerful music against frustration from science. 


Walker Fuchs

Graduate Student

Walker received his B.A. in Biochemistry from Wheaton college (MA) where he completed his honors thesis on heart regeneration in zebra fish. He then went on to work at Dana Farber Cancer institute & Harvard medical school as a a research assistant where he researched the use of micro RNAs as Biomarkers for cancer. In the Su lab, Walker is interested in the effects of membrane biophysics on immune activation in the anti-tumor response. Walker enjoys hiking and woodworking in his spare time. 


Ron Orbach, PhD

Postdoctoral Associate

Ron obtained his PhD in chemistry from the Hebrew University. Fascinated by the molecular self-assembly process, Ron joined Jonathon Howard’s lab and investigated the microtubule core structure of the cilia – the axoneme. Currently, Ron explores the role of membrane curvature on the self-assembly of TCR clusters. Outside the lab, Ron enjoys his time with the family.


Qian Xiao, PhD

Associate Research Scientist

Qian obtained her Ph.D. in Biochemistry and Molecular Biology from Shanghai Institute of Biochemistry and Cell Biology, Chinese Academy of Sciences, China. She recently illustrated a tumor cell-secreted protein Dickkopf2 induced pathway that inhibits cytotoxicity of tumor infiltrating lymphocytes, and identified it as a potential target for immunotherapy in colorectal cancer. In the Su lab, Qian is interested in the molecular mechanism of chimeric antigen receptor-triggered T cell activation and in developing new tools for improving T cell-based cancer immunotherapy.
Qian likes traveling, hiking, photography, and art.

Jianjian Guo

Graduate Student

Jianjian received her B.A. in Life Sciences from University of Science and Technology of China, and studied CRISPR knock out screen in search for novel T cell immune suppressor against cancer at Yale during graduation thesis. In the Su lab, she's interested in developing novel cell therapy against solid tumors. Outside science, Jianjian enjoys Sci-fi, psychology, movies and pop music.
