Career

Radenovic studied physics at the University of Zagreb, where she wrote her Master thesis on Raman spectroscopy of Beta-Carotene^{[citation needed]}. She then joined Giovanni Dietler's Laboratory of Physics of Living Matter, then located at University of Lausanne, and in 2003, she graduated with a PhD on cryo atomic force microscopy.^[3][4] For postdoctoral studies she went to work at University of California, Berkeley with Jan Liphardt.^[5] In 2008, she became an assistant professor at EPFL where she established the Laboratory of Nanoscale Biology.^[2] In 2015, she was promoted as an associate professor.^[1]

Research

Radenovic's area of research is the development of experimental techniques for the study of molecular and cell biology making use of biosensors and optical imaging. In particular, she is interested in single-molecule biophysics.^[6][7]

Her research follows three main trajectories. First, she employs nanopores applied on suspended 2D material membranes, standard silicon-nitride membranes, and in glass nanocapillaries to study and manipulate single molecules.^[8][9][10] Then, Radenovic studies the function of single molecules, especially protein and nucleic acid interactions, via optical tweezers, optical wrench system, anti-Brownian electrokinetic trap, and a combination of nanopores or nanocapillaries with optical tweezers.^[11][12][13] Finally, based on single molecule localization microscopy, she designs super-resolution optical microscopes to extract quantitative information on single molecules.^[14][15][16]
