Dr. Harvey Risch is Professor Emeritus of Epidemiology at Yale University's School of Medicine and School of Public Health. An author of over 400 peer-reviewed research papers and over 50,000 citations, his focus has been on etiology, treatment and prevention of cancer -- notably ovarian, pancreatic, lung, and stomach --  genetic disposition, diet, immunology, and contraceptive hormones.  He is also the editor of the International Journal of Cancer and an associate editor of the Journal of the National Cancer Institute. During the Covid-19 pandemic, Dr Risch was an early critic of the federal lockdown policies and the government's mishandling of the pandemic. He was one of the early high profile medical experts to oppose the government's suppression of hydroxychloroquine for the treatment of SARS-2 infections, and later gave testimony before a Senate committee about that fact. Prior to Yale, he taught at the University of Toronto.  Dr Risch earned his medical degree from the University of California at San Diego, as well as a PhD in mathematical modeling of infectious epidemics from the University of Chicago.  More recently he has become a senior scholar at the Brownstone Institute where he publishes critical articles about the CDC, the Covid vaccines, and the government capture of so-called science.
