Sharlene M. Day, MD recently joined Penn Medicine in July 2019 as an Associate Professor of Medicine and Genetics, and Director of Translational Research for the Penn Cardiovascular Institute at the University of Pennsylvania. She earned her B.S from the Massachusetts Institute of Technology in 1991 and her MD from New York University School of Medicine in 1995. She completed her internal medicine residency and cardiovascular medicine fellowship at the University of Michigan, followed by postdoctoral research fellowships in cardiovascular biology and physiology. At the University of Michigan, she established the Program for Inherited Cardiomyopathies and Arrhythmias, where she served as the Director for 12 years. Dr. Day sees patients with hypertrophic cardiomyopathy and other genetic heart conditions in the Penn Center for Inherited Cardiac Disease. Her research program primarily focuses on hypertrophic cardiomyopathy (HCM), and integrates basic, translational and clinical science. Outside of work, she enjoys spending time with her family, running, swimming and cycling.

Ulla Lilienthal

Ulla Lilienthal

Research Lab Manager at University of Michigan
 ullalil@med.umich.edu

Ulla grew up on a small farm on the southeast coast of Sweden. After high school, she went on a one year adventure as an au pair to the United States. She got a scholarship to Kutztown University, and pursued a PhD in immunology at the University of Maryland, College Park. She loved the research and wanted to get a medical degree as well, but took time off to raise her family.

As her children were getting older, Ulla taught science at private high schools. She later got a job working as a dish washer at the Life Sciences Institute, University of Michigan. She made a friend in the HR department, who knew about her science background and interest in research, and alerted Ulla to a job opening as a lab manager. Ulla was hired by Zhaohui Xu as a lab manager. Then she joined the lab of Dan Southworth to do Cryo-Elecronmicroscopy and used Sec-MALS Chromatography to make purified protein. With her passion for research rekindled, Ulla went back to school to pursue a Master’s degree in chemical biology from the University of Michigan (received 2017). Now Ulla works with Andrea Thompson in the Department of Cardiology at the University of Michigan. She is still working as a lab manager but also is heavily involved in the research projects, which include differentiating stem cells into cardiomyocytes. She also collects heart cells from open heart surgeries. Given her early interest in science and medicine, she loves the opportunity to bring clinical questions into a research setting.

When Ulla is not in the lab, she enjoys spending time with friends and her three children. Her daughter lives abroad so she spends a lot of time on FaceTime and sending emojis across the ocean! She has always loved animals, and spends time with her son’s Goldendoodle (her fur-grandbaby) and enjoys being around horses as often as she can.
