Speranta Tanasescu, PhD, is Senior Researcher I and head of the Laboratory of Chemical Thermodynamics in the “Ilie Murgulescu” Institute of Physical Chemistry of the Romanian Academy, Bucharest. Dr. Tanasescu obtained a PhD in Physical Chemistry from the Romanian Academy in 1979 and has served as a supervisor in chemistry since 2002. She received the “Gh. Spacu” Award from the Romanian Academy in 1972. Her thematic research focuses on activities with impact in the following domains: materials science, nanoscience and nanotechnologies, new sources of energies, nanosafety, and nanomedicine. Her research is significant for understanding processing-structure relationships as well as for finding key parameters in relation to bio-reactivity of the nanomaterials with impact in both nanosafety and nanomedicine research.
