Dr. Roybal is an Assistant Professor in the Department of Microbiology and Immunology at the University of California, San Francisco. He is a full member of the Parker Institute for Cancer Immunotherapy and an inaugural Chan Zuckerberg Biohub investigator. He received a doctorate in Immunology from the University of Texas Southwestern Medical Center at Dallas in 2013. There he studied the fundamental cellular and biochemical mechanisms that regulate T cell activation at the system-scale using quantitative live cell fluorescent imaging in Christoph Wulfing's laboratory. Dr. Roybal then moved to Wendell Lim's lab at the University of California, San Francisco and the Howard Hughes Medical Institute as a Jane Coffin Childs Memorial Fund Postdoctoral Fellow. There he developed a new class of synthetic receptors called Synthetic Notch receptors that have far-reaching implications for cell therapies for cancer, autoimmunity, and regenerative medicine.

Daniel B. Goodman, Ph.D. 

Jane Coffin Childs Postdoctoral Fellow (co-advised w/Jeff Bluestone and Alex Marson)

B.S. Bioengineering/Bioinformatics - University of California, San Diego

Ph.D. Bioinformatics and Integrative Genomics - MIT and Harvard Medical School (Laboratory of George Church)

About me: My work combines computational modeling, DNA synthesis, and multiplex screens to generate and measure targeted libraries of thousands of genetic elements, genes, and genomes. My current research is focused on understanding and manipulating T-cell signaling through the design and testing of of synthetic cell-surface receptors.

Raymond Liu, Ph.D.

B.S. Biology – Stanford University

Postdoctoral Fellow – NIH T32 Training Grant

Ph.D. Biology – California Institute of Technology (Laboratory of David C. Chan)

About me: My previous work has focused on the regulation of cytoskeleton regulators and dynamins, and on the implications of their interactions in human disease. My current research is focused on engineering improved T-cell responses for immunotherapy.
