Research

I study the system created in ultrarelativistic heavy-ion collisions with the ALICE experiment at the Large Hadron Collider (LHC).  In these collisions it is expected that a hot, dense, deconfined medium of quarks and gluons is formed, known as the Quark-Gluon Plasma (QGP).  By measuring the properties of this medium, we learn about nuclear matter, the strong interaction, and Quantum ChromoDynamics (QCD), at extreme temperatures and densities. 

My research focuses on three main areas:

1. Exploring the transition from small (proton-proton) to large (heavy-ion) collisions, in order to describe the observed phenomena within a consistent and coherent framework across system size. 
2. Investigating the thermodynamic and hadrochemical properties of the QGP and the phase diagram of nuclear matter through measurements of the fluctuations of conserved quantum numbers, particularly strangeness and baryon number. 
3. Probing the properties of the QGP by measuring the energy loss of high-momentum quarks and gluons as they traverse the medium before fragmenting into "jets" of hadrons.
