Ultrafast Optical Spectroscopy
dobromil.respekta(at)physik…
I am a postdoctoral researcher specialising in ultrafast spectroscopy of perovskite materials, with expertise in femtosecond transient absorption, time-resolved photoluminescence, and nonlinear optical measurements to probe carrier dynamics and energy transfer processes. I have obtained my BSc and MSc in Nanotechnology from Gdańsk University of Technology, and a PhD in Physics from Ghent University.
Start: Aug 2025

Alumni
The speckles
The Speckles are a group of StranksLab members with topics related to optical spectrosocpy, microscopy, or optoelectronic devices – in many cases with Simon acting as their daily supervisor. In addition to their regular subgroups, The Speckles meet along with Simon for deeper discussions and engagement with their research projects.
Regular speckles include Alan Baldwin, Barney Lewis, Hayley Gilbert, Cullen Chosy, Shenyu Nie, Shabnum Maqbool, and Melissa Fitzsimmons
