820: Studying the Molecular Information Cells Use to Move Through Their Environments - Dr. Michelle Starz-Gaiano
Dr. Michelle Starz-Gaiano is Professor and Chair of Biological Sciences at the University of Maryland Baltimore County (UMBC). Michelle’s research uses fruit flies to examine how cells in the body go to the right place at the right time. Understanding why and how cells use their genetic information to move through the body is critical because if this movement doesn’t happen correctly, it could, for example, impact embryo development or affect how immune cells mobilize after an injury. Conversely, preventing cancer cells from moving could keep cancer from spreading to other parts of the body. Michelle often spends her free time cooking and baking. Her kitchen looks a little like a lab, and she enjoys experimenting with making different foods. Michelle and her family also like to spend time together, travel, and listen to music. She received her bachelor’s degree in biology from the Massachusetts Institute of Technology and her PhD in Developmental Genetics from New York University.
