Chi Zhang
Assistant Project Scientist

Dr. Zhang's research focuses on the study of steroid treatments, including the use of dexamethasone (Dex), which mediated the increase of intraocular pressure (IOP) and the risk of ocular hypertension leading to steroid-induced glaucoma. Dex treatment can lead to irregular trabecular meshwork (TM) structure and potentially reduce outward flow of intraocular fluid through altering Wnt signaling. In addition, Dr. Zhang uses novel Wnt small molecule regulators to investigate whether these modulators would affect Dex-mediated phenotype on primary human TM cells..

Luis Sanchez
Graduate Student Researcher

Luis Sanchez is a PhD candidate at UCLA studying under Professor Jie J. Zheng. He completed his Bachelor of Science at San Francisco State University in the field of cellular and molecular biology. As an undergraduate student, he was a member of the distinguished NIH-Minority Access to Research Careers (MARC) training program where he conducted research under the mentorship of Professor Laura W. Burrus focusing on Wnt morphogen gradient formation. Prior to his graduate studies, Luis joined Eureka Therapeutics, a bay area biotechnology start-up focused on the development of T-cell immunotherapies for the treatment of solid tumors. He is now focused on the isolation, culture, and mechanical property characterization of cells residing within the trabecular meshwork, an ocular tissue responsible for intraocular pressure homeostasis. In the future, Luis wishes to leverage his research background to contribute to the development of glaucoma therapeutics.

Christiana Han
Lab Assistant

Christiana is a recent UCLA grad, graduating with Bachelors in Physiological Science and Minor in Environmental Systems and Societies. Currently she studies WNT expressions of WNT - mimic treated cells derived from cell lines. She is also working on analyzing RNA sequencing data via R to see how Dex affects WNT Signaling Expression.

Andrew Bennecke
Student Researcher

Andrew is a fourth-year Computational & Systems Biology undergraduate at UCLA with a minor in Neuroscience and Entrepreneurship. Andrew is working on the development of a mathematical model of this pathway in order to identify trends and biomarkers which could be altered in order to delay, or even prevent oncogenesis in the human eye.
