Lauren McCarthy (she/her/hers)
Postdoctoral Scholar, IRACDA Fellow
Lauren comes from Jacksonville, FL and graduated with her B.S. in Chemistry from the University of Florida with a minor in Physics. Her interdisciplinary interests led her to pursue a Ph.D. in physical chemistry at Rice University in Houston, TX where she characterized the optical properties of single nanoparticles. In the Biteen Lab, she is studying how bacterial cells organize themselves, particularly under stress. In addition to her interests in the lab, Lauren loves to listen to podcasts, take her dog on long walks, and spend time with her family.
