Nassim Usman
Nassim Usman is an organic chemist turned biotech operator who runs Totus Medicines, an Emeryville, California company using a DNA-encoded covalent library platform (OmniDEL) paired with machine learning to build small-molecule drugs against targets long considered undruggable. He took the CEO chair in December 2023 alongside a $66 million Series B, and its lead drug, TOS-358, is the first covalent PI3K-alpha inhibitor in the clinic. Over three decades he has moved from bench chemistry on RNA and ribozymes to the top jobs at Sirna Therapeutics, Catalyst Biosciences, and Principia Biopharma, plus a stint as a venture investor at Morgenthaler Ventures.
Wenqing Yao
Wenqing Yao is the founder and CEO of Synnovation Therapeutics, a precision-oncology biotech in Wilmington, Delaware. A medicinal chemist by training, he spent nearly two decades at Incyte building and leading its discovery chemistry engine, a stretch that produced five FDA-approved drugs including Jakafi. In 2021 he left to start Synnovation, which launched publicly in January 2024 with a $102 million Series A to advance best-in-class small molecules against highly validated targets, led by a CNS-penetrant, isoform-selective PARP1 inhibitor and a mutant-selective PI3K-alpha inhibitor.
