Many-body QCD phenomena in high-energy proton and nuclear collisions
In 2022, I was awarded Emmy Noether Group Funding by German Research Foundation (DFG) to conduct a six-year research programme on the Many-body QCD phenomena in high-energy proton and nuclear collisions at the Institute for Theoretical Physics at Heidelberg University. My group will develop the microscopic description of the emergent collective phenomena in systems of varying sizes and varying energy scales.
Emmy Noether was an outstanding mathematician with major contributions to mathematics and theoretical physics. In particular, she discovered that every continuous symmetry has a corresponding conserved charge. This principle is now known as Noether’s theorem. Emmy Noether was also a pioneering woman in science, who defied the norms of her time. I am honoured to receive the grant named after her.

I am a theoretical physicist working on many-body phenomena emerging from fundamental interactions of elementary particles.
In my research I connect models of nuclear, hadronic and particle physics with methods of relativistic hydrodynamics, statistical physics and out-of-equilibrium dynamics to study the hot and dense nuclear matter created in high-energy hadron collisions. My work has contributed to a better understanding of fundamental states of matter, thermalisation of isolated quantum systems, and how a fluid-like behaviour emerges from a relatively small number of constituents interacting via the strong force.
I work at Institute for Theoretical Physics at Heidelberg University. Previously, I was a senior research Fellow at Theoretical Physics department at CERN, Switzerland. My first postdoctoral position was at Heidelberg University, Germany. I worked in the groups of Prof. Dr. Jürgen Berges and Priv.-Doz. Dr. Stefan Flörchinger at the Institute for Theoretical Physics under the collaborative research project SFB 1225 ISOQUANT. Before that I was a PhD student at Nuclear Theory Group at Stony Brook University, US (PhD advisor Prof. Dr. Derek Teaney).

I was a member of the collaborative research center “Isolated quantum systems and universality in extreme conditions”.
My work was centered on understanding the early times dynamics in heavy ion collisions and the universal aspects of information loss. I also maintained interest in other stages of the collision like hydrodynamic expansion and hadronization.

I am fascinated by many-body physics emerging from interactions of elementary particles in a hot and dense nuclear matter created in high-energy hadron collisions at particle accelerators like LHC (CERN) and RHIC (BNL). I am trying to understand the properties of the new state of nuclear matter—the quark-gluon plasma (QGP), which is formed at extreme temperature and density. Outside hadron collisions, such conditions can be found only at the beginning of the Universe and in violent neutron start mergers.
Recently I have been particularly interested in the formation of the quark-gluon plasma at the earliest stages of the collision. I use a weakly coupled kinetic theory of quarks and gluons to perform state-of-the-art simulations elucidating the phenomena of equilibration and fluid-like behaviour of relatively small number of particles interacting via the strong force. I have also worked on the hydrodynamic descriptions of quark-gluon plasma expansion and I am actively working on improving the conversion from fluid fields to measurable hadrons at late stages of the collision.
