About Me

I have a joint postdoctoral research position at Prof. Dr. Jürgen Berges and Dr. Stefan Flörchinger groups at the Institute for Theoretical Physics under the collaborative research project SFB 1225 ISOQUANT.
Previously I was a PhD student at Nuclear Theory group at Stony Brook University.

I am interested in high multiplicity particle collisions at LHC and RHIC, because they can create Quark Gluon Plasma — a new form of matter, where protons and neutrons melt into quarks and gluons. Astonishingly, these tiny droplets of matter interact so strongly, that they can be effectively described as a fluid — the perfect fluid. Understanding the properties of QCD matter at extreme conditions is the aim of my research. Click on figures below to find out more!

Student responses

  • Aleksas was always very welcoming and took the time to answer any questions the students had. I loved his strategy of reviewing the formulas before discussing that weeks homework — this form of review sincerely helped me succeed in this course. His quizzes were challenging but in a positive way and they were always relevant. I would love to see him become a professor one day and attain his career goals.

    from PHY 132 recitation evaluations
  • I think the instructor was more valuable than the course itself. Any TA for these recitations will help with homework problems and review tests, but there was a lot of effort put in with this TA. The practice quizzes and thoughtful explanations were a big help for learning and reviewing the material, and was the link he sent us to physics lectures by a professor at MIT.

    from PHY 132 recitation evaluations
  • The TA, Aleksas, is a wonderful TA. He would do a fantastic job in teaching the entire course. His expectation of the students is perfect, yet he somehow is also a fantastic teacher (even in giving quizzes, which is rare). He gives useful equations on the board and does not mind helping a student through a difficult problem, because he knows that some problems the students cannot do alone. Please give this man a medal.
