When he was young, Luke Engelking’s mother asked him what he wanted to be when he grew up. His answer? “’A mad scientist,’” he said.

Engelking certainly was exposed to the idea of a career in science and medicine early, as his mother pursued a second career as a physician’s assistant during his high school years. “Unfortunately, she had a number of rare autoimmune diseases and was often in and out of doctors’ offices,” Engelking said. “From then on, I always knew I wanted to go to med school. However, I wasn’t always certain that I wanted a Ph.D.”

Engelking ended up doing both. He went to medical school at the University of Texas Southwestern Medical Center, where he got his M.D.–Ph.D. in the lab of Nobel laureates Michael Brown and Joe Goldstein, best known for their discovery of the low-density lipoprotein receptor and its regulation of cholesterol metabolism. He enjoyed working with Brown and Goldstein.

“It was a very productive time,” Engelking said. “I really didn’t appreciate working under their aegis when I was doing it. … Once you’re out on your own, everything is more of a struggle.”

Engelking has embraced that struggle. After a residency at Massachusetts General Hospital and a clinical and research fellowship back at UT Southwestern, he not only began seeing patients as an attending physician but also opened his own research lab as an assistant professor in the departments of internal medicine and molecular genetics, studying the role of sterol receptor element-binding proteins in colon cancer growth and progression.

Now an associate professor, Engelking balances his time between seeing patients and conducting research. In addition, he is working to establish a clinical research program in colon cancer genetics so data on mutations of enrolled patients can be made publicly available to researchers at UT Southwestern and around the world.

“It’s my hope that we’ll be able to synergize the clinical work with the work going on in the lab,” he said. “It’s a challenge to try to get all of this work to align — I hope I’m making progress, but we’re not quite there yet.”
