Postdoctoral Researcher

Dr. Tomasz Kruczyński (since 01/2023)

 Tomasz-Webversion
 
Tomasz graduated from Gdańsk University of Technology, Poland, in 2009 (magister inżynier (mgr), equivalent to MEng, Master of Engineering in Chemical Technology) and earned his doctoral degree in the field of inorganic synthesis (highly sensitive magnesium cluster chemistry) with Prof. Hansgeorg Schnöckel at Karlsruhe Institute of Technology (KIT), Germany, in 2015. After working in industry, Tomasz continued to pursue an academic career and moved to the U.S. to join the Stollenz Group as full-time postdoctoral research scientist in inorganic/synthetic chemistry. He is interested and trained in various fields of inorganic synthesis, coordination chemistry, crystallography, computational chemistry, as well as photoluminescence and NMR spectroscopy.
 
Tomasz is the Crystallographic Facility Manager of our new Bruker Venture dual-source single-crystal diffractometer and the Manager of our spectrofluorometer and UV-Vis facility. He also operates and maintains our new Thermo Scientific FlashSmart Elemental Analyzer (installed in 2025).
