During the past 30 years Sulak has explored the micro-world of particle physics, mapping out the weak interaction, one of the four fundamental forces of nature. In the early 70’s he designed and built the calorimeter and performed the analysis that discovered neutral weak currents using neutrino beams at Fermilab. At Brookhaven Lab, he and his collaborators, using his calorimeter and electronics, were the first to observe neutrino and antineutrino elastic scattering. This work was the first to demonstrate that two of the four forces, the weak and the electromagnetic, are unified. Sulak is co-initiator and principle investigator of other larger detectors. These include the astrophysical MACRO observatory deep under land in the Gran Sasso tunnel of Italy, the superconducting storage ring g-2 experiment at Brookhaven Lab which recently observed a potential second deviation from the Standard Model, the quartz fiber Cherenkov calorimeter for the CMS colliding beam detector at CERN in Geneva, and the K2K experiment (the first to shoot neutrinos a long distance (250 km) from an accelerator to a detector) which recently confirmed the atmospheric neutrino oscillation results.
