Christopher B Anderson, MD

Dr. Larisa Geskin is a Professor of Dermatology (in Medicine) at Columbia University Medical Center and Director of the Comprehensive Skin Cancer Center (CSCC) at the Division of Cutaneous Oncology in the Department of Dermatology. She is a world-renowned specialist in the diagnosis and management of cutaneous lymphomas and other cancers of the skin. Her other areas of expertise include melanoma screening, prevention, medical and surgical therapy, and management of high risk for skin cancer populations. Dr. Geskin is using state-of-the-art methods in melanoma screening and surveillance including Mole Mapping (body mapping) and dermoscopy. She was involved in development of novel melanoma detection methods, including MelaFind among others. Dr. Geskin's team aims to provide multidisciplinary care to skin cancer patients, to conduct cutting edge clinical and basic science research, and to train medical students, residents and fellows in the area of cutaneous oncology. Dr. Geskin completed her residency in Dermatology at University of Pittsburgh Medical Center (UPMC), and a two-year fellowship in cutaneous oncology at University of Pittsburgh Cancer Institute (UPCI) with Louis Falo, MD, PhD, Professor and Chairman, Department of Dermatology, UPMC, and with John Kirkwood, MD, Professor and Vice Chairman for Clinical Research, Director of the Melanoma Center at the UPCI. She is a diplomat of the American Academy of Dermatology, member of the Society for Investigative Dermatology, the International Society for Cutaneous Lymphomas, and US Cutaneous Lymphomas Consortium. She authored over 30 peer-reviewed articles in the field of cutaneous oncology. Her research interest focuses on Cutaneous T-cell lymphoma (CTCL) and biomarkers discovery, genetic profiling and regulation, development of immunotherapy for melanoma and lymphoma.

Thomas C Randall, MD is a gynecologic oncologist focused on meeting the individual needs and goals of women with gynecologic cancers. Dr. Randall provides care for all gynecologic cancers and for women at increased risk for gynecologic cancers. He has a particular focus on providing safe surgical care for women with gynecologic cancers, including advanced or recurrent ovarian cancer, uterine, cervical and vulvar cancer. Dr. Randall also performs surgery for complex gynecologic conditions. He has extensive experience and expertise in minimally invasive surgeries, and he has performed over 1000 surgeries with the DaVinci surgical robot. Additionally, Dr. Randall has expertise in radical cancer surgeries, including fertility sparing surgeries for gynecologic cancers. Dr. Randall studied at Bowdoin College where he graduated Magna Cum Laude with Honors in English Literature and won the College Prize for Bowdoin from the Academy of American Poets. He then attended Johns Hopkins University School of Medicine and completed his residency in Obstetrics and Gynecology at Johns Hopkins Hospital. Next, he completed his fellowship in Gynecologic Oncology at the University of Pennsylvania in Philadelphia. Dr. Randall practiced gynecologic oncology and gynecologic surgery at the University of Pennsylvania and the Massachusetts General Hospital before coming to Columbia. Dr. Randall is a leader in global health. He is the Chair of the Mentorship and Training Committee of the International Gynecologic Cancer Society, which supports 22 gynecologic oncology fellowships in low- and middle-income countries where gynecologic cancer surgery was not previously available. He also serves as an international mentor for gynecologic oncology fellowships in Haiti and Rwanda.

Kelley Yan, MD, PhD, is a physician-scientist trained in diverse disciplines including clinical gastroenterology, structural biology, and stem cell biology. This multidisciplinary background provides her with a unique perspective and opportunity to study intestinal stem cell (ISC) biology at the molecular, cellular, and tissue levels. Her love of science began with an appreciation for undergraduate studies in chemistry and the physical sciences, which evolved during graduate school into a desire to understand how 3D structure or molecular form enables biological function and confers specificity in protein-protein or protein-nucleic acid interactions. She has experimentally examined these interactions in signal transduction—particularly ligand/receptor interactions—using structural biology and biophysical methods. Her medical training deepened her passion for clinical gastroenterology and guided her toward regenerative medicine, fueled by a personal commitment to serving her patients. As a postdoctoral fellow, Dr. Yan pursued further scientific training in ISC biology and developed expertise in rigorous mouse genetics, in vivo models, ex vivo 3D organoid culture systems, and single-cell genomics to study stem cell fate decisions.
