Yuyan Cheng, PhD

Principle Investigator / Assistant Professor of Ophthalmology

Yuyan received her PhD from the University of Miami in Biochemistry and Molecular Biology (mentor Dr. Richard Jope). She then went on to the University of California, Los Angeles for her postdoctoral training in the laboratory of Dr. Dan Geschwind. Her work leverages functional genomics, computational biology, and experimental animal models to understand the biology of neurodegeneration and to discover potential therapeutic for neural repair.  Yuyan started her lab at Penn in January 2024 studying retinal degenerative disorders using single-cell and spatial genomics approaches. Outside of the lab, Yuyan looks for ways to stay active and creative. She plays a mix of sports, including swimming, skiing, and tennis.

Jeff Maurer

Lab Biostatistician

Jeff graduated from Rowan University and from Boston University’s Masters in Bioinformatics program. During COVID, Jeff joined Emory University to work as a Data Analyst in the Immunology lab of Dr. Jeremy Boss across the street from the CDC. Along with various multi-omic analyses, he spent much energy trying to make himself redundant, educating the rest of the lab on bioinformatics analysis and encouraging the wet lab to branch out. Back home in Philadelphia, he joins the Cheng Lab to lead its bioinformatics within the Molecular Ophthalmology department at the University of Pennsylvania.

Cassidy Poon

Lab Technician

Cass graduated with Honors bachelor’s degrees in Biology and English at the University of Delaware in May 2024. During her undergraduate years, she cultivated a strong background in both clinical ophthalmology and molecular biology research in the Pennsylvania-Delaware area. Today, she is assisting the Cheng lab with ocular nerve damage gene therapeutic projects through mouse model studies. Cass plans to use her research field experience and passion for service to continue her path in ophthalmology as a future medical professional. Outside of work and studies, she enjoys gaming and writing. A Delawarean at heart, Cass also loves to explore the East Coast through travels with friends and family.
