Turning Pages, Changing Lives: Dr. Simon Warren’s Path from Literature to Dermatopathology

Dr. Simon Warren loves the written word, studying Ancient Greek, Latin, and Linguistics while playing competitive squash at Cambridge University. One day, he picked up a book that changed the direction of his life: The Selfish Gene by Richard Dawkins. “I decided I wanted to know more about evolution, then more about DNA. I started chatting with people in science and medicine and decided to switch from the arts to the sciences, which is not something normally done in Britain. Most people go to medical school right from high school. I had to go back and take the high school science exams and work 9 months in a research lab to qualify for medical school.”

Warren attended United Medical and Dental School of London University, after which he was a house officer in medicine for 6 months and surgery for 6 months. During this time, he realized that much of what happened to his patients depended on the pathology report, so he decided to pursue pathology training first in the UK and then in the US, followed by a two-year bench research fellowship in Immunobullous disease. He then transitioned to the University of Texas Southwestern Medical Center for a dermatopathology fellowship. “During my research fellowship, I was very fortunate and ended up with a first-author publication in the New England Journal of Medicine.”

He was recruited to the University of Indiana where he spent 16 years as director of the Dermatopathology Division, fellowship director, and several years as associate director of the IHC lab. “I began looking for a place that had more molecular offerings in the laboratory. There is a molecular revolution going on right now. It is crashing over pathology and dermatopathology. I wanted the opportunity to work with some of the top colleagues in the field and to have an opportunity to continue research.” He decided that the University of Michigan was the place to go.

That is new to me.” He is also continuing his research. “I am happy that I got two publications accepted and published in the last year, one in spatial transcriptomics for melanoma and one in molecular drivers of histiocytosis.” He also teaches fellows, residents, and medical students, which he finds invigorating.

“In the next ten years, I would like to bring some additional molecular methods to bear on melanoma. I want to improve our ability to diagnose it, apply spatial transcriptomics to improve our understanding of it, and find better ways to treat it.” Solving challenging disease cases is what makes pathology so enjoyable for him. “I like figuring out tough, impactful cases and, as a result, improving my understanding of a disease process. I love working with clinicians.”

He is now running the first Dermatopathology lab in Tajikistan and is training other people.” There were numerous challenges to overcome, such as adapting to electrical service at 240 volts instead of the 110 volts in the United States, and maintaining equipment in a country lacking the necessary infrastructure.

He has three grown “American kids”: Vincent is getting married and works for Epic in Madison, Wisconsin; Lisa works in merchant banking in Boston, and the youngest, John, is at Indiana University, Bloomington studying computer programming. His wife, Kristi, is a runner, gardener, and home remodeler. Warren himself loves music. “I have been to four or five Lollapaloozas in Chicago and 3 Coachellas in the California desert.” He enjoys the outdoors, traveling, skiing, cycling, and sailing. He sails anything from dinghies to yachts. However, he no longer plays squash. “My knees just cannot handle it anymore. My 85-year-old Dad is the better tennis player at this point.”
