International Linear Collider
Gollin has worked on particle physics experiments studying muon scattering (1975–1981, intended to test the ideas of "Quantum Chromodynamics"), neutral K meson decay parameters (1980–1993, measuring things relating to "CP violation"), and electron-positron annihilation (1993–2005, measuring production and decay properties of heavy quarks). His current research focuses on technical issues associated with the design and construction of the "International Linear Collider", a very large electron-positron colliding beams facility intended to shed light on the origins of the masses of the fundamental particles.
