[1][2] He was an international leader in the application of genome sequencing, animal models, and systems biology approaches to virology and immunology.
[2] Initially, he was interested in dentistry, but after his first year of dental school at the University of Pennsylvania, Katze decided to take his career a different direction.
Later, when Katze was working as a research assistant at the University of Pennsylvania and, simultaneously, at the Wistar Institute, he discovered his passion for virology.
[2] In January 2016, an internal investigation by the university found that Katze had violated the school's sexual harassment policies in his relationships with two female employees; a related investigation by Washington's medical school found that he had diverted university resources for personal gain and recommended an audit.
[9] In 1971, Katze graduated from Boston University magna cum laude and was inducted into the prestigious Phi Beta Kappa honor society.
[2] One year later at the ISICR Meeting in Paris he was honored with the Milstein Award, which represents the zenith of scientific achievement in this area of research.
