About Qiong Gan
I am a board certified cytopathologist, working as an assistant professor in the Department of Pathology at The University of Texas MD Anderson Cancer Center (MDACC). I completed my residency training in Pathology at the Mount Sinai Morningside and Mount Sinai West, NY and Surgical Pathology as well as Cytopathology fellowships before I joined the staff at MDACC in 2018. I have also finished my PhD study in Molecular Physiology and Medicine at University of Virginia. I am currently the director of cytopathology fellowship program. My research interests include diagnostic cytology, especially pancreatic and thyroid cytology, and the application of unique cytopathology material such as malignant fluid in cancer research.
