Siddhartha Mukherjee, a professor at Columbia University's School of Medicine, is a "quadruple threat," according to Gates.
"Doctors are deemed a “triple threat” when they take care of patients, teach medical students, and conduct research. Mukherjee, who does all of these things at Columbia University, is a “quadruple threat,” because he’s also a Pulitzer Prize-winning author," Gates wrote in a review for Mukherjee's "The Gene" in 2016.
In the book, Mukherjee takes the reader on a journey through the "past, present, and future of genome science," Gates writes, "with a special focus on huge ethical questions that the latest and greatest genome technologies provoke."
