Zhaolan Zhou

Zhaolan Zhou is a Professor of Genetics at the University of Pennsylvania School of Medicine and a Core Member of the Epigenetics Institute. His research focuses on understanding the epigenetic mechanisms underlying brain development and neurological disorders.

Education:

• B.S. in Bioengineering from Nankai University (1991)
• M.S. in Genetics from Chinese Academy of Sciences (1994)
• Ph.D. in Molecular and Cellular Biology from Harvard University (2001)

He completed postgraduate training as a Helen Hay Whitney Postdoctoral Fellow at Harvard Medical School and Children's Hospital Boston (2003-2008) and as an S.O. Mast Fellow at the Marine Biological Laboratory in Woods Hole (2002).

Research Interests:

Dr. Zhou's laboratory investigates the epigenetic control of genome function in brain development and disease, with particular focus on neurogenetics and neuroepigenetics. His team explores how DNA methylation, histone modification, and genomic editing mechanisms contribute to neurodevelopmental and neuropsychiatric disorders including Rett syndrome, CDKL5 deficiency disorder, autism spectrum disorder, and major depressive disorder. The lab employs cutting-edge genomic technologies, cellular and physiological assays, and genetically modified mouse and human induced pluripotent stem cell models to uncover pathophysiological mechanisms and develop therapeutic interventions.

Three major research themes guide the Zhou laboratory: (1) Understanding the molecular basis of stress vulnerability and its relationship to major depressive disorder; (2) Gaining pathogenic insights into X-linked disorders like Rett syndrome and CDKL5 deficiency disorder by overcoming challenges posed by X chromosome inactivation; and (3) Investigating how epigenetic regulation controls synaptic gene expression in the brain, particularly how DNA methylation interacts with histone modifications in the context of autism spectrum disorders.

Research Trends:

Dr. Zhou's recent publications demonstrate a consistent focus on epigenetic mechanisms in neurodevelopmental disorders, particularly X-linked conditions. His work increasingly integrates advanced genomic technologies with sophisticated animal models to dissect disease mechanisms at cellular and circuit levels. There's a clear progression toward developing therapeutic strategies, with several recent papers exploring the reversibility of symptoms in disorder models. His research bridges basic molecular mechanisms with translational applications, as evidenced by studies identifying potential biomarkers and treatment-responsive endpoints for conditions like Rett syndrome.

Scientific Contributions:

• Development of innovative models to overcome X-linked cellular mosaicism in studying disorders like Rett syndrome
• Pioneering work on the role of epigenetic regulation in stress vulnerability and depression
• Advancing understanding of how DNA methylation and histone modifications collaboratively regulate synaptic gene expression
• Developing CRISPR-based epigenomic editing approaches for locus-specific manipulation

Training and Mentorship:

Dr. Zhou has mentored numerous graduate students, postdoctoral fellows, and research specialists who have gone on to successful careers in academia, industry, and medicine. His lab currently includes postdoctoral fellows, PhD students from multiple graduate groups, research specialists, and undergraduate researchers. His former trainees have secured positions at prestigious institutions including Yale University, Stanford University, and the Children's Hospital of Philadelphia, with several receiving competitive fellowships and awards during their training.

Research Environment:

The Zhou laboratory is situated within the Department of Genetics at the University of Pennsylvania School of Medicine, with strong connections to the Epigenetics Institute and multiple graduate groups. The lab employs a multidisciplinary approach, combining "omics" technologies, epigenetic remodeling using adapted CRISPR systems, mouse phenotyping, confocal microscopy, electrophysiology, and biochemical characterization to address complex questions in neuroepigenetics.
