Meet the Cook Lab
Mark Charlton-Perkins

PhD student in MDB program
Mark Charlton-Perkins was raised on a farm in the eastern Free State in central South Africa. After high school, he moved to New Zealand where he completed a BS in neuroscience at the University of Otago. He then moved to Cincinnati with his wife, Katie. His research is focused on understanding the evolutionary mechanisms driving lens formation, which should aid efforts in developing better treatments for congenital eye defects.

Tiffany Cook, PhD

Assistant Professor
Tiffany received her PhD in Biomedical Sciences/Molecular Biology and is an Assistant Professor at Cincinnati Children's. Her research focuses on understanding the molecular basis of eye development, differentiation of color photoreceptor subtypes in the Drosophila retina, cell-specific regulation of opsin gene expression, and mechanisms of cell-specific transcriptional activation and repression.

John Mast

Research Assistant II
John Mast grew up in Cincinnati and received a B.A. in Biology and Psychology from Knox College (Galesburg, Illinois) in 2010. John joined the Cook lab in 2011, and his research is primarily focused on understanding how retinal integrity is modulated by support cells in the Drosophila eye.

David Terrell

PSTP student in MDB program
David Terrell was born in Dallas, TX, and attended Southwestern University and Texas State University where he pursued degrees in music, audio engineering and biochemistry. He is currently in the MD / PhD program at the University of Cincinnati. His research focuses on the Otd / Otx family of transcription factors, which have conserved functions in photoreceptor development and differentiation in animals ranging from Drosophila to humans.

Baotong Xie, PhD

Postdoctoral fellow
Baotong Xie received his PhD in the Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, where he studied the structure and function of human ventricular myosin light chain 1 and its application in diagnosing myocardial infarction. Currently, he is using biochemistry and developmental genetics to investigate molecular mechanisms underlying neural fate decisions required for forming the photoreceptor mosaic in the Drosophila eye.
