Gary M. Wessel, PhD, Professor of Biology at Brown University, is an experienced researcher in the field of reproduction and early development. He served as Editor-in-Chief and as a member of the editorial board of several journals in the area of reproduction and development.Julian L. Wong, PhD, is an active scientist working to identify novel therapeutics. He previously worked on fertilization and cellular reprogramming, and served for a decade as the Managing Editor for a reproduction journal.Carmen J. Williams, MD, PhD, Senior Investigator at the National Institute of Environmental Health Sciences, has studied basic and clinical reproductive biology for more than thirty-five years and published extensively in the field. She was an Associate Editor for two reproduction journals and co-directed the Frontiers in Reproduction summer research course at the Marine Biological Laboratory (Woods Hole, MA).Mark A. Johnson, PhD, Professor of Biology at Brown University, has studied plant reproduction for twenty-five years. He is on the Board of the International Association of Sexual Plant Reproduction Research and hosted the 27th International Congress on Sexual Plant Reproduction in 2024.Harvey Florman, PhD, is Professor Emeritus of Cell and Developmental Biology at the University of Massachusetts Medical School. His research focused on aspects of fertilization and sperm physiology in mammals. He was Editor-in-Chief of journals in the field and directed the Frontiers in Reproduction summer research course at the Marine Biological Laboratory (Woods Hole, MA).
