During his PhD, Jongmin identified the function of an uncharacterized gene (he and his advisor named it Kumgang), which was critical for silencing somatic genes during fly spermatogenesis (Kim, ..., Fuller, 2017). After joining a chromatin lab as a postdoc, he continued his work on gene silencing in mouse spermatogenesis, focusing on Polycomb group proteins in modulating chromatin architecture (Kim and Kingston, 2022; Kim, ..., Kingston, 2023). He is excited to investigate how these chromatin-modifying proteins block the misexpression of unwanted genes and safeguard male germ cell fate.
Jongmin is from Korea and came to the US for graduate school. He likes to swim and hike. His recent memorable hike was the "Subway" at Zion. He is looking forward to exploring many trails and gorges around Ithaca.

Julia is a PhD student in the field of Biochemistry, Molecular and Cell Biology. She grew up in San Diego, California and obtained her bachelor’s degree from Dartmouth College in New Hampshire. There, she majored in Cell and Molecular Biology and studied the Wnt signaling pathway in Drosophila Melanogaster. Outside of the lab, she enjoys singing jazz and playing the trombone. She also loves hiking and exploring the outdoors.

Helen is a PhD student in the field of Genetics, Genomics and Development (GGD) co-advised by Dr. Jongmin Kim and Dr. Paula Cohen. Before coming to Cornell, she obtained her B.S. in Biology and Mathematics from Northeastern University in 2024. During undergrad, Helen worked as a research assistant in Dr. Sandeep Robert Datta’s lab at Harvard Medical School, where her research focused on the role of Ms4a6d in the progression of Alzheimer's Disease in mouse models. Her current research focuses on the roles of CBX2 and CBX7, polycomb repressive complex proteins, in mouse spermatogenesis. Outside of the lab, Helen enjoys reading, playing the cello, and exploring Ithaca with her friends.

Hongjiang is a PhD student in the field of Biochemistry, Molecular and Cell Biology(BMCB). He was born and raised in Chengdu, China, and obtained his B.S. from Nankai University, advised by Xinglu Huang. He spent 1 year as a visiting scholar in the Shen lab at UCSF, where he studied functional genomics in the context of Alzheimer’s disease and contributed to the development of various sequencing methods and tools. He then spent 2 years at Tsinghua, studying epigenetics and transposons. In Kim Lab, his research focuses on chromatin-based gene regulation during spermatogenesis, leveraging advanced tools in functional and computational genomics.
