Research Abstract:

Dr. Zhong is interested in how cellular machines sense intrinsic and extrinsic cues and alter chromatin landscapes to generate adaptive responses. Her group focuses on epigenetic regulation by exploring how chromatin dynamics is established, maintained, erased, and inherited over time, and how altered chromatin modifications lead to improved plant traits and environmental adaptation. They combine functional genomics and high-throughput proteomics and genomics techniques together with traditional genetic and biochemical tools to understand the function and mechanism of epigenetic processes and develop novel chromatin-based technology for biomass production and agricultural improvement.

Mentorship and Commitment to Diversity Statement:
Engaging students from underrepresented groups in research is a significant goal of my career development. I have long been interested in promoting a strong and diverse community in the scientific education and research. I consider teaching and mentoring students from diverse backgrounds a special privilege that comes with profound responsibilities as well as personal gratification.
