Hanadie Yousef, PhD
Chief Executive Officer and Co-Founder
Chief Executive Officer and Co-Founder, Juvena Therapeutics
Dr. Hanadie Yousef is a leading expert on the biology of aging and mechanisms underlying tissue degeneration with over two decades of experience in biomedical research. In 2018, she launched Juvena Therapeutics, a venture-backed biotechnology company mapping the therapeutic potential of secreted proteins and accelerating their translation into engineered biologics that promote tissue repair and restoration of function and health to treat degenerative diseases.
Under Dr. Yousef’s leadership, Juvena has leveraged its Artificial Intelligence (AI)-enabled platform to develop a proprietary, pro-regenerative protein library that enabled the discovery and development of a growing pipeline of biologics for myopathy and metabolic diseases. The company’s lead asset, JUV-161, promotes muscle regeneration and metabolism. It is in IND-enabling studies for the treatment of orphan disease Myotonic Dystrophy Type 1 and is expected to enter the clinic in 2024. In addition, Juvena is progressing multiple preclinical programs across metabolic and fibrotic disease areas, including a novel preclinical obesity asset, JUV-112, that uniquely enhances lipid metabolism to induce weight loss through a non appetite-suppressing mechanism.
Dr. Yousef’s high-impact published research has been supported by fellowships and grants from the National Institute of Health (NIH), National Science Foundation, SPARK, and the California Institute for Regenerative Medicine and led to multiple issued and pending patents. She has received multiple awards and recognition for her entrepreneurship and innovation, including FierceBiotech’s “Fiercest Women in Life Sciences,” Business Insider’s “30 Leaders Under 40 Changing Healthcare in 2023,” Endpoints’ “The 20(+2) under 40,” and Pharmaceutical Executive’s“Emerging Pharma Leader”in 2023, San Francisco Business Times’ 2024 Women Who Lead in Life Sciences , and the 2022 Biocom Catalyst award. She is also a regularly invited speaker at industry and innovation events.
Dr. Yousef earned her B.S., summa cum laude from Carnegie Mellon University and a PhD from UC Berkeley as an NSF graduate research fellow then completed a 5-year postdoctoral fellowship at Stanford School of Medicine as an NIH fellow and SPARK scholar.
