Marek Flaska

Marek Flaska is an Associate Professor in the Ken and Mary Alice Lindquist Department of Nuclear Engineering at Pennsylvania State University, College of Engineering. His research focuses on nuclear detection systems, neutron and gamma-ray spectroscopy, and radiation measurement technologies. He is affiliated with the Institutes of Energy and the Environment and contributes to integrated energy systems research.

His research interests include neutron and gamma radiation detection, pulse shape discrimination, scintillation counters, liquid and organic scintillators, silicon photomultipliers (SiPM), Monte Carlo simulations, and nuclear non-proliferation. His work aims to improve the accuracy, efficiency, and portability of radiation detection systems for both civilian and security applications.

The recent publications highlight a strong trend in digital signal processing for radiation detection, with significant emphasis on machine learning applications for pulse shape discrimination, multiplexing schemes for compact neutron cameras, and characterization of new-generation silicon photomultipliers. His work bridges fundamental detector physics with practical engineering solutions for reactor instrumentation and nuclear security.
