Tahamtan Ahmadi
Tahamtan Ahmadi built his career in the hard middle of biotechnology - where a scientific idea must survive evidence, regulation, and scale. At Genmab, his remit now stretches from discovery to medicine, and his public philosophy keeps returning to curiosity, collaboration, and patient impact.
Reinilde Heyrman
Reinilde Heyrman has spent decades turning clinical uncertainty into decisions. Her method is neither grand nor theatrical: start with the science, plan for the detour, and make sure someone owns the next move.
Allison Luo
Allison Luo, MD is the Chief Medical Officer of Mirador Therapeutics, a San Diego precision-medicine company that launched in 2024 with more than $400 million to attack immuno-fibrotic diseases using its Mirador360 development engine. A physician scientist with more than two decades in clinical development, she was CMO of Prometheus Biosciences before Merck bought it for $10.8 billion, and has since reassembled with that team to build Mirador. She sits on the board of Triveni Bio and has held medical-leadership roles across Ventyx, Biora, Iveric Bio and Bristol Myers Squibb.
Ahsan Arozullah
Ahsan Arozullah, MD, MPH is Executive Vice President of Research and Development and Chief Medical Officer at TerSera Therapeutics, a Deerfield, Illinois specialty pharmaceutical company focused on oncology, CNS disorders and rare disease. A Northwestern-trained physician with a Harvard MPH, he spent over 15 years at Astellas, rising to Senior Vice President and Head of Oncology Development, where he helped validate claudin 18.2 as a cancer target through the pivotal SPOTLIGHT trial of zolbetuximab. He pairs two decades of clinical research with academic roots in health literacy at the University of Illinois and serves on the board of Darul Qasim College, working at the intersection of medicine and Islamic bioethics.
Bob Wassman
Dr. E. Robert (Bob) Wassman is Chief Medical Officer and Executive Vice President of Clinical Development at MARAbio, a Utah-based diagnostics company building a maternal blood test to identify an autoimmune subtype of autism. A board-certified pediatrician and medical geneticist with more than 40 years in the field, he has served as chief medical officer for a long roster of genetic-testing pioneers including Genzyme Genetics, Ambry Genetics, Rosetta Genomics and Good Start Genetics, repeatedly turning frontier laboratory technology into clinical service across reproductive medicine, cancer, and neurodevelopmental disability.
Scott Roth
Scott Roth is a cardiologist who spent two decades reading echocardiograms before deciding the ICU needed a faster way to see the heart. As founder and CEO of ImaCor, he built hemodynamic ultrasound (hTEE) around the disposable, pencil-thin ClariTEE probe that stays in a patient for up to 72 hours, giving clinicians a live look at cardiac filling and function instead of waiting on lab results. In 2022 ImaCor and Clarius released the Zura Handheld, billed as the world's first handheld TEE system, putting that view in a 22-ounce device.
Jorge Dimartino
Jorge F. DiMartino, M.D., Ph.D., is Chief Medical Officer and Executive Vice President of Clinical and Translational Development at Plexium, a San Diego-based biotech pioneering targeted protein degradation. A physician-scientist trained in genetics, immunology, and pediatric oncology across UC Berkeley, Cornell, UC San Diego, and Stanford, DiMartino has spent over two decades advancing cancer drugs from bench to bedside. His fingerprints are on three now-marketed therapies: vismodegib, venetoclax, and enasidenib - each a breakthrough in its own right. At Plexium, he oversees clinical programs targeting SMARCA2, IKZF2, CDK2, and CRAF using the company's DELTA Discovery platform, a novel approach to degrading proteins previously considered undruggable.
