dr. M. Morales Masis (Monica)

Assistant Professor

About Me

My passions are material science research, education and art. Currently, my work focusses on the development and understanding of functional optoelectronic materials and thin films: transparent conducting oxides (TCOs), carrier selective contacts, hybrids, and discovery of new materials by combinatorial synthesis. Our optoelectronic materials find application in energy conversion and/or efficient devices like solar cells, light emitting diodes and transparent electronics.

Before coming to UTwente, I have been team leader for the transparent electrodes development at the Photovoltaics and Thin-Film Electronics Laboratory (PVLab) of the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. I obtained my Ph.D. in Physics from Leiden University, The Netherlands in 2012, working on resistive switching memories.
