Dr. Valdemaras Aleksa serves as an Associate Professor at the Institute of Chemical Physics within Vilnius University's Faculty of Physics. His research spans vibrational spectroscopy, conformational analysis of molecular structures, ionic liquids, and the polychromy of artworks, alongside physics education. His scientific interests focus on using spectroscopic methods (Raman, IR, NMR) to investigate molecular structures and dynamics, particularly in silicon-containing compounds and ionic liquid systems. His work combines experimental approaches with computational methods like DFT and MP2 to understand molecular conformations and interactions. His research has significant applications in materials science, chemistry, and cultural heritage preservation. Alexa's publications demonstrate a consistent focus on molecular structure analysis through spectroscopic techniques, with recent work emphasizing ionic liquids, silicon compounds, and their conformational properties. His research shows strong international collaboration, particularly with US scientists. Member of VU Teacher Training Professional and Adjunct Pedagogical Studies Program Committee (since 2015) Expert of the Study Quality Assessment Center (SKVC) (since 2018) Member of evaluation committee for best dissertations in physical sciences (2019) Member of Dr. R. Gaška scholarship awarding commission (since 2020) Dr. Aleksa teaches Applied Spectroscopy in the Faculty of Physics, Health Physics and Life Sciences in the Faculty of Medicine, and Didactics of Physics in the Faculty of Philosophy. He has supervised numerous student theses and two doctoral students. His grant leadership includes projects on molecular structure analysis and collaboration with US scientists, as well as participation in EU-funded educational initiatives connecting universities.
