More about the PI

Dr. Xinshu (Grace) Xiao received her B.S. degree at Tsinghua University, Beijing, China.  She then went to the Massachusetts Institute of Technology (MIT) for graduate studies, earning the M.S. and Ph.D. degrees in 2000 and 2004, respectively. During this period, she worked on mathematical modeling and systems identification with Dr. Roger D. Kamm and Dr. Richard J. Cohen, respectively, at MIT. After receiving her Ph.D degree in the Division of Health Sciences and Technology (HST), a joint program by MIT and Harvard Medical School, Dr. Xiao joined the laboratory of Dr. Chris B. Burge in the Department of Biology at MIT for postdoctoral training, where she carried out bioinformatic,genomic and experimental studies of alternative splicing.

​In 2008, Dr. Xiao joined the faculty at the University of California, Los Angeles. She is now the Maria R. Ross Endowed Professor of the Department of Integrative Biology and Physiology. She also serves as the Director of the Bioinformatics Interdepartmental Program. In addition to her primary appointment in the Department of Integrative Biology and Physiology, Dr. Xiao is affiliated with the Institute for Quantitative and Computational Biology, the Molecular Biology Institute, and the Jonsson Comprehensive Cancer Center. She is a training faculty with several Ph.D. programs, including the Bioinformatics IDP, Molecular Biology IDP,  Molecular, Cellular and Integrative Physiology IDP, and the Bioengineering Ph.D. program. She is also a participating faculty in the Computational and Systems Biology undergraduate program.

Scientists and Postdoctoral Scholars

Dr. Jae Hoon Bahn

Associate Project Scientist

Jae is an Associate Project Scientist in the Xiao lab. He received his Ph.D. in comparative experimental medicine from the University of Tennessee and joined the Xiao lab in 2011. Jae is working on diverse molecular and biochemical experiments for RNA biology in the lab. He likes cooking, watching Netflix, swimming, and playing piano.

Dr. Ting Fu


Ting is a postdoctoral fellow in the Xiao lab. She earned her PhD in MCIP at UCLA in 2022. She developed a new MPRA system, namely MapUTR, to uncover functional variants in the 3′ UTR. Ting also studies the functions of RNA editing in basic biological systems and disease models.

Dr. Giovanni Quinones-Valdez


Giovanni is a postdoctoral fellow in the Xiao lab. He earned his PhD in Bioengineering at UCLA in 2022. His research mainly focuses on the study of RNA variants, including RNA editing and genetic variants. He studies the function and regulation of such variants by developing novel bioinformatics methods and algorithms and apply them to large-scale data analysis.
