Barbara A. Baird

Barbara A. Baird is the Horace White Professor in the Department of Chemistry and Chemical Biology at Cornell University. Her research focuses on biophysical studies of membrane receptor proteins, signal transduction, and cellular responses. She investigates molecular mechanisms of receptor-mediated cell signaling, particularly the high affinity receptor (FcεRI) for immunoglobulin E (IgE), which plays a key role in inflammatory and allergic immune responses. Her work integrates experimental approaches to study receptor dynamics and signaling pathways, with applications to cancer and neurodegenerative diseases. Baird's laboratory employs quantitative microscopy and biophysical methods to analyze cellular responses and membrane interactions.

Barbara Baird is a Professor of Chemistry at Cornell University, specializing in Biochemistry, Biophysics, Cell Biology, and Immunology. Her research focuses on understanding membrane organization and its role in cellular processes, particularly in immunology and signal transduction. She investigates lipid rafts, fluid/fluid phase separation, and the dynamics of membrane domains using advanced biophysical techniques. Her work explores how lipid and protein interactions influence signaling pathways, such as those involving FcεRI and Lyn kinase. Baird's research also addresses the structural and functional properties of plasma membrane compartments, including their role in immune responses and cellular signaling.
