Felipe Sierra, PhD

Felipe Sierra, Ph.D. is CEO of Geroscience Consulting LLC. He is best known for his contributions to the development of the field of geroscience, a concept he developed while serving as Director of the Division of Aging Biology at the National Institute on Aging (NIA), part of the National Institutes of Health (NIH) in the USA.

Trained as a biochemist in Chile, he obtained a PhD in Biochemistry and Molecular Biology from the University of Florida in 1983 and has since worked in Academia, Industry and Government, in a career that spans multiple geographic areas including South America, USA, Europe (Switzerland and France) and most recently, the Middle East.

Dr. Sierra served as Director of the Division of Aging Biology, NIA/NIH from April 2006 to March 2020, where he developed the concept of Geroscience and created the trans-NIH Geroscience Interest Group (GSIG). After his tenure at NIA/NIH he worked as Director of Geroscience for the Inspire program in Toulouse, France, and most recently, as Chief Scientific Officer at Hevolution Foundation, a non-profit organization headquartered in Riyadh, Saudi Arabia. He retired from that position in March 2025 to start a private consulting venue, Geroscience Consulting LLC.
