Sharon Marr, PhD

Sharon received her B.S. in Microbiology from the University of Oklahoma and a PhD in Biochemistry, Molecular and Cell Biology from Cornell University. She worked as a lab manager at the University of California at Berkeley and then at Brandeis University before joining the Kingston lab. In her free time when she is not purifying SWI/SNF, she is interested in the biochemical analysis of PRC1 domains required for nucleosome compaction in vitro.

Jesse Cochrane,PhD

A long time Canadian, Jesse is also a long time member of the Kingston. She joined in January 2008 having completed her B.S. in Chemistry at MIT and her PhD in Molecular Biophysics and Biochemistry at Yale University. Jesse uses cryo-electron microscopy to look at the structure of the human SWI/SNF complex.

Fu-Kai Hsieh

Fu-Kai received his Ph.D. from Rutgers University. Prior to his doctorate degree, he obtained his B.S. from Tunghai University and M.S. from National Chung Cheng University in Taiwan. He joined the Kingston lab in November 2013 as a research fellow. He is interested in the roles of lncRNA in regulating chromatin structure and gene expression.

Jongmin Kim, PhD

Jongmin received his B.S. in Life Sciences from POSTECH, South Korea, and obtained his Ph.D. in Chemical and Systems Biology from Stanford University. He joined the Kingston Lab in March of 2016 as a research fellow. He is interested in the chromatin structure regulation by CBX2 in the male germ line of mouse.

Mattia Lion, PhD

Mattia received his B.S. and M.S. in molecular biology from University of Padova, Italy and his Ph.D. in biomolecular sciences from University of Trento, Italy. In between, he spent a year at Imperial College of London and a year at NIEHS in North Carolina. He joined the Oettinger lab in June 2014 as a research fellow and is now transitioning into Kingston Lab to finish his project and explore new ideas. He is interested in understanding the role of chromatin in controlling antigen receptor rearrangement and, more generally, the role of chromatin dynamics during lymphoid development.

Christos Tsokos, MD, PhD

Christos is a postdoctoral fellow interested in the molecular mechanisms of chromatin remodeling. He obtained a B.A. in Biology from Cornell, PhD in Biology from MIT, M.D. from Harvard University, and completed residency and fellowship training in gastrointestinal pathology at UCSF before joining the Kingston laboratory in 2017.

Jinjin Zhu, PhD

Jinjin received her B.S. in Biology from Ocean University of China and studied Drosophila eye development for her Ph.D. at Indiana University Bloomington. In 2018, she joined the Kingston Lab as a research fellow to understand how Polycomb Group proteins regulate gene expression during mammalian neural development.


140x140

Wojtek Siwek, PhD

Wojtek trained in Poland, Portugal and the UK. He joined the Kingston Lab as a research fellow in 2020. He is interested in cellular memory of gene expression states. He uses interferon stimulation as a model to study this phenomenon on a molecular level. He is a big fan of the outdoors.


Graduate Students


140x140

Theresa Oei

Theresa received her B.S. in Molecular Biophysics and Biochemistry from Yale University in 2015. Afterwards, she worked on developing genome editing tools at MIT in Feng Zhang's lab as a research associate. She is currently a graduate student in the Chemical Biology program at Harvard and joined the Kingston lab in May of 2018. She is interested in the role of PRC1 phase separation in gene silencing and chromatin compaction.


140x140

MacKenzie Mauger

MacKenzie received her B.A. in Biochemistry and Biology from the University of Pennsylvania in 2019. She is currently a graduate student in Harvard's Biological and Biomedical Sciences program, and she joined the Kingston lab in August of 2020. She is interested in the role of phase separation in PcG-mediated epigenetic memory and the redundancy of CBX subunits in canonical PRC1.


Bioinformatics Specialist

Manashree Damle

Manashree received her B.Pharm from University of Pune in India and M.S in Biotechnology from the University of Pennsylvania. She joined the Kingston Lab in 2017 and analyzes NGS data in the lab.


Research Technicians


140x140

Ethan McCaslin

Ethan received his B.A. in Biochemistry and his M.A. in Biotechnology from Boston University. He joined the lab in August of 2020 and is interested in the composition of PRC1.4 and the impact that modifications can have on its ability to regulate gene expression.


140x140

Emma Steinson

Emma received her B.A. in Biology from the University of Virginia in 2020 and joined the Kingston Lab in September 2020. She is interested in studying how PRC1 regulates gene expression during development.
