Floralba López, Ph.D.

Biography

Floralba López obtained her undergraduate degree in Chemistry from the University of Los Andes (ULA, Venezuela) in 2000. She then attended the Physics graduate program at the Institute for Scientific Research (IVIC, Venezuela) and got an M.Sc. in 2005. That same year she became faculty of the Chemistry Department at ULA and finished her PhD there in 2016. Her thesis focused on anisotropic diffusion in confined systems. One of her published contributions was recognized with the regional prize of Science and Technology. She was a visiting faculty at the Center for Physics at IVIC 2010 and she served as head of the Physical Chemistry of Fluids and Interfacial Phenomena Laboratory (2014-2016). Floralba is currently on sabbatical time from the Chemistry Department at ULA, Venezuela. At present, she is a tutor at Yachay Tech University, Ecuador, where she has begun a research project on spintronic applications of molecules with chiral centers.
