Group Leader


Dr. Bartlomiej Graczykowski obtained his Ph.D. in Physics in 2012 (AMU, Poznan, Poland). He was appointed as a postdoctoral researcher at ICN2 Barcelona in Spain (2013–2016) and MPIP Mainz in Germany (A. von Humboldt Foundation fellowship, 2016–2017). Currently, he is an assistant professor at the Faculty of Physics of Adam Mickiewicz University in Poznan, Poland, and a guest researcher at the Max Planck Institute for Polymer Research in Mainz, Germany. His research activities include advanced inelastic light scattering techniques (Brillouin, Raman) applied to nanostructures, hypersound, and heat transport at the nanoscale in confined and organized systems.

Postdoctoral Researchers

Dr. Thomas Vasileiadis obtained his diploma in Physics from the University of Patras (Greece) in 2011 with a specialization: “Theoretical and Computational Physics, Astronomy and Astrophysics”. After graduation, he worked for three years as a research assistant at the Institute of Chemical Engineering at High Temperatures, part of the Foundation of Research and Technology Hellas (ICEHT-FORTH). In 2014, he obtained his Master’s degree in Materials Science. From 2014 to 2019 and he worked at the Fritz Haber Institute of the Max Planck Society in Berlin (Germany). There, he studied electron-phonon coupling with Femtosecond Electron Diffraction. In 2019 he defended his Ph.D. thesis entitled: “Ultrafast Energy Flow and Structural Changes in Nanoscale Heterostructures”. In 2019 he joined the group of B. Graczykowski as a postdoctoral scientist at the Adam Mickiewicz University in Poznan (Poland), and as a guest scientist at the Max Planck Institute for Polymer Research in Mainz (Germany). Since November 2020 he is appointed as a Marie Skłodowska-Curie postdoctoral fellow at the Faculty of Physics of Adam Mickiewicz University.

MSc Maciej Kasprzak obtained his MSc in physics in 2016 in Nanostructures Physics Division, Faculty of Physics, Adam Mickiewicz University in Poznan, Poland. His master thesis topic was the theoretical calculation of the electromagnetic field around the coplanar waveguide. The research area of his Ph.D. studies is the nanoscale heat transport in silicon membranes with or without patterned structures. His additional research interests focused on computational physics: molecular dynamics, Monte Carlo simulation, i.e., dynamic lattice liquid model (DLL), and the use of graphics cards GPU to speed up the simulations.
