معرفی
Dr. Romualdas Kisielius is a Senior Researcher at the Institute of Theoretical Physics and Astronomy (ITPA) at Vilnius University, specializing in theoretical atomic physics with applications in astrophysics. His work focuses on atomic spectroscopy, electron and photon interactions with ions, correlation effects, and plasma modeling across temperature ranges.
His research interests include theoretical atomic spectroscopy, electron and photon interactions with ions, correlation effects in ions, and low- and high-temperature plasma modeling for astrophysical applications. Dr. Kisielius has made significant contributions to atomic data for various ions including Ne II, C II, Fe II, O II, and S II, with applications in nebular physics and cosmic chemical evolution studies.
Analysis of his publication record from 1998-2021 reveals a consistent focus on atomic data generation for astrophysical diagnostics, particularly concerning ionization states of elements across the periodic table. His work bridges atomic physics with observational astronomy, providing critical data for interpreting spectral lines from cosmic objects.
Dr. Kisielius has received significant funding from the National Science Foundation (USA) as principal co-investigator for projects related to atomic physics needs for spectroscopic diagnostics of cosmic chemical evolution (2020-2023) and spectral diagnostics of heavy elements at high redshift (2012-2016).
He has supervised doctoral students including Frances H. Cashman (2020, University of South Carolina, USA) and has presented his work on the ADAMANT database at international workshops including the Atomic Data and its Incorporation into Cloudy workshop in Belfast (2013) and the 23rd Meeting of the Atomic and Molecular Data Centres at the International Atomic Energy Agency in Vienna (2015).
