I graduated as a physicist at the UA in 1995, and obtained my Ph.D. in 1999 also at the UA. My thesis work focused on Bose-Einstein condensation in atomic gases, which had been observed experimentally not long before causing a lot of excitement. My research on this new state of matter was performed under the promotorship of prof.dr. Jozef Devreese in the laboratory "TFVS" (theoretical solid state physics). Afterwards I went as a postdoctoral researcher to Harvard to work in the laboratory of prof.dr. Isaac Silvera, where we investigated multielectron bubbles in helium, and where I learnt some experimental skills to complement my background as a theorist. I still collaborate with Ike and work part-time as associated researcher in Harvard, where we now focus on high-pressure experiments on hydrogen. After my postdoc, I applied for a job at the UA, where I was appointed as a lecturer in theoretical physics. I have since then built up a research group with a bunch of talented young grad students, and I have provided service to the physics community in Belgium as the president of our national physics society.
At our lab in the physics department, TQC (theory of quantum and complex systems) we investigate quantum many body theory for condensed matter systems, ultracold atomic gases, nanoscopic superconductivity, superfluidity. Our method of choice is path integral theory, and our excursions in the mathematical properties of these integrals have led to results in what is becoming known as complexity science, in particular in the field of econophysics. My main current research topics are ultracold atomic Fermi gases, superconductivity, optical properties of solids, and the further development of path integral theory.
