Eric Londin

Assistant Professor in Computational Medicine Center, Department of Pathology

Short Bio

Dr. Londin received his Ph.D. from Stony Brook University in Genetics. There, he studied the role of fibroblast growth factors in the early patterning of the nervous system. Following the completion of his Ph.D., he began working in the human genetics field as a research fellow at the Coriell Institute for Medical Research (Camden, NJ). While at Coriell, Dr. Londin, began working in the computational biology field, and specifically in population genetics. His worked focused on the identification of efficient ways to measure admixture within the human population. Since 2011, Dr. Londin has been a member of the Computational Medicine Center at Thomas Jefferson University, first as a postdoctoral research fellow, and currently as an assistant professor. His current work is focused on studying the human microRNA-ome (miRNAs). Of particular interest, is the characterization of the number and composition (miRNA isoforms or isomiRs) with in the human genome, as well as elucidating their roles in human disease. In addition to short-RNAs, Dr. Londin has an interest in DNA sequencing and its uses in a clinical setting. As next-generation sequencing becomes more prevelant in a clinical setting, have a better understanding of the benefits and limitations of this technology is of great importance. He has published numerous articles in the field of RNA and DNA sequencing, and sits on the editorial board and acts as a reviewer for multiple journals.
