Dr. Tomasz Karol Pietrzak earned, from the Warsaw University of Technology (WUT), a M.Sc. in Physics (2008) and a Ph.D. in Physics (2012) with greatest honors. He is now the Associate Professor of the Faculty of Physics at WUT. His work in solid-state physics has been devoted mostly to the investigation of the nanocrystallization phenomenon in electronic and mixed (electronic--ionic) conducting glasses, resulting either in a giant increase in the electrical conductivity or confinement (stabilization) effects. His research includes both experimental and computational methods. He gained international experience during several study visits, including the Massachusetts Institute of Technology, the Rensselaer Polytechnic Institute, the University of Waterloo, and the National University of Singapore. He pays much attention to teaching new generations of physicists. He was granted numerous student awards of the “Golden Chalk” for conducting lectures on computer programming and tutorials on the fundamentals of physics. He proudly serves as an advisor to Ph.D. students and surrounds himself with a young group of talented and hard-working graduate students.
