David L. Katz

David L. Katz (born February 20, 1963) is an American physician and former director of the Yale-Griffin Prevention Research Center that was founded at Griffin Hospital in Derby, Connecticut in 1998.

Previously, Katz was a clinical instructor in medicine at the Yale School of Medicine. Katz formerly served as associate director for nutrition science at the Rudd Center for Food Policy and Obesity at Yale, following his appointment in 2005. Although Yale-Griffin Prevention Research Center is part of the Yale School of Public Health, Katz has not had an academic appointment with Yale since 2016 and is no longer academically affilated with the university. Katz has authored over 100 scientific papers and written newspaper and magazine articles, including a recurring column in O starting in March 2002 and later discontinued. In 2000, Katz founded the Integrative Medicine Center at Griffin, which ceased operating in November 2014. Katz is a contributor and advisory board member for Naked Food Magazine.

In 2015, Katz wrote two positive reviews in his Huffington Post blog for a science fiction book that he had published under a pseudonym, without disclosing that he was the author of the book; Huffington Post retracted the posts.

In March 2020, Katz was invited by John Ioannidis to join in a proposed meeting intended to convince President Donald Trump not to employ lockdown measures during the COVID-19 pandemic; however, the meeting ultimately did not take place.

Katz received a BA degree from Dartmouth College, an MD degree from the Albert Einstein College of Medicine, and an MPH degree from Yale School of Public Health. He is board certified in preventive medicine.
