Dr. Michael Doser is research physicist at CERN, working towards measuring for the first time the gravitational interaction between matter and antimatter through the use traditional photochemical emulsion. The AEgIS collaboration carrying out this experiment consists of 16 institutes and universities, and about 60 scientists from a very diverse range of physics expertise, among them atomic physics, nanotechnology, physical chemistry, plasma physics, laser physics, Rydberg atoms, cryogenic electronics, high energy physics, physics of positronium, microwaves and cavities, dilution refrigerators, ion cooling through lasers, ...
