In October, President Joe Biden awarded the National Medal of Science and the National Medal of Technology and Innovation to 20 Americans who have made exemplary achievements in science, technology and innovation to strengthen the nation’s well-being. Among those awarded the National Medal of Science was Gregory Petsko, who has been an 91ÑÇÉ«´«Ã½ member since 1987.

Petsko

The is the nation’s highest scientific honor. Since 1959, it has been bestowed on “individuals deserving of special recognition for their outstanding contributions in biology, computer sciences, education sciences, engineering, geosciences, mathematical and physical sciences, and social, behavioral, and economic sciences, in service to the nation.”

is a professor of neurology at Brigham & Women’s Hospital and Harvard Medical School. In his early career, Petsko’s lab was dedicated to understanding enzymes’ catalytic activity and structure. He and his colleague Dagmar Ringe made foundational discoveries in structural biology, including obtaining the first time-lapse images of the complete catalytic cycle of cytochrome P450 at an atomic resolution using low-temperature X-ray crystallography.

Since the early 2000s, has focused on finding treatments for neurodegenerative diseases such as Alzheimer’s, Parkinson’s and amyotrophic lateral sclerosis, or ALS. His team developed a gene therapy for the most common form of ALS. This induces overexpression of the nonsense-mediated decay factor UPF1 and reduces neuronal toxicity in human cell culture and rodent models of ALS. In addition, Petsko and his colleague have developed therapeutics for Alzheimer’s and Parkinson’s. All of these therapies will soon be tested in clinical trials.

His many awards include the Siddhu Award and the Martin J. Buerger Award from the American Crystallographic Association, the Pfizer Award in Enzyme Chemistry from the American Chemical Society, the Lynen Medal, the McKnight Endowment for Neuroscience Brain Disorders Award, a Guggenheim fellowship and the Max Planck Prize.

He is a member of the American Association for the Advancement of Science, the National Academy of Sciences, the National Academy of Medicine, the American Academy of Arts and Sciences and the American Philosophical Society. In addition, Petsko is a past president of the 91ÑÇÉ«´«Ã½ and also of the International Union of Biochemistry and Molecular Biology.

The from the White House stated: “Those who earn these awards embody the promise of America by pushing the boundaries of what is possible. These trailblazers have harnessed the power of science and technology to tackle challenging problems and deliver innovative solutions for Americans, and for communities around the world.”
