Researcher in Positronium Physics:
*Using positronium (Ps) to measure the gravitational free fall of antimatter: Does it fall at the same rate or possess a type of antigravity?
*1S-2S Experiment: Motivation is to shed light on the so-called 'proton radius puzzle'. What is causing this? Extra dimensions? QED needs modification?
*A Bose-Einstein condensate (BEC) of Ps: Via stimulated annihilation, the first gamma ray laser would result! Another goal is to create a positronium atom laser.
