Every year, female STEM professionals are invited to share their experiences and interest in science, technology, engineering, and math with the participants of the madiSTEM Conference.


The 2024 Morning speaker is Dr. Sophia Leung. Dr. Sophia Leung, (M.D.) is an Orthopedic surgeon who specializes in Hand and Upper Extremity surgery. She is also currently serving as the Orthopedic Site Director for Sentara Medical Group, and the Orthopedic Surgery Section Chief at Sentara RMH.  Dr. Leung came to the US from Hong Kong at age 5. She originally received her undergraduate degree in Industrial design from Virginia Tech. Dr. Leung graduated from the University of Maryland School of Medicine and completed her residency at University of Maryland Medical Center and R. Adams Cowley Shock Trauma Center to become part of the 7% of board-certified orthopedic surgeons who are female. She then pursued a fellowship in hand and upper extremity surgery at UPMC in Pittsburgh. Fun fact: She has two young children and if she wasn’t a surgeon, she would be a pastry chef. Dr. Leung is obsessed with cats but is also allergic to them!

The 2024 Afternoon speaker is Dr. Carole Nash. Dr. Carole Nash is a JMU Professor of Geography in the department of Integrated Science and Technology (ISAT) and is also currently the JMU College of Integrated Science and Engineering (CISE) Director of Diversity, Equity, and Inclusion. She received her doctorate in anthropology/archaeology from the Catholic University of America.  She is a fellow Duke having earned her undergraduate degree in anthropology and philosophy from JMU. Dr. Nash has over 40 years of experience in cultural resource management (National Park Service, National Forest Service, State of Virginia). She is the founder of the nonprofit Mountain Valley Archaeology, a member of the Virginia Museum of Natural History in Waynesboro’s board of trustees, and is the director of the Environmental Archaeological Laboratory at JMU.
