Dr. Kristen Lynch is a Professor and Chair of Biochemistry and Biophysics at the University of Pennsylvania. Kristen's research focuses on alternative splicing. Her lab is investigating how cells decide when to use an entire portion of the DNA instruction manual versus when to exclude parts of the instructions that are not useful or would be harmful. In particular, Kristen is interested in alternative splicing in the immune system and what happens when cells are faced with an immune challenge. When she's not at work, Kristen loves being outdoors. She spends her free time kayaking, paddle boarding, biking, hiking, and doing yoga. She received her B.A. in biochemistry and her Ph.D. in biochemistry from Harvard University. Afterwards, Kristen pursued postdoctoral training at the University of California, San Francisco. She served on the faculty at the University of Texas Southwestern Medical Center prior to joining the faculty at the University of Pennsylvania in 2009. Kristen is the recipient of many awards and honors for her work, including a National Science Foundation CAREER Award. She joined us for an interview to talk about her experiences in life and science.
