Ana received an M.S. in physical chemistry from University of Belgrade, Serbia, and a Ph.D. in physical chemistry and surface science under the supervision of John T. Yates, Jr. at the University of Virginia. Her doctoral research focused on electron-hole recombination rates in TiO2 powders, which control the efficiency of TiO2-based solar-driven technologies: catalysis and PV cells. Ana was a postdoctoral researcher at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. At NIST, she worked with Andrei Kolmakov on developing ambient pressure scanning electron microscopy to image charge transport in semiconductor nanowires.
In Drs. David Bell and Philip Demokritou’s groups, Ana’s work involves in situ imaging of biomaterials in media relevant to nanotoxicology by transmission electron microscope (TEM) and cryo-scanning electron microscopy (SEM).
