Born in Gisborne, New Zealand, Parke attended Edmund Campion College, Gisborne and St Peter's College, Auckland and the University of Auckland in New Zealand. He was a graduate student of Sidney Coleman at Harvard University, obtaining a PhD in theoretical particle physics in 1980. He held a postdoctoral fellowship at the Stanford Linear Accelerator Center (1980–1983) before moving to the Fermi National Accelerator Laboratory.^[2]

He is an originator of Parke–Taylor amplitudes, which he developed with his colleague, Tomasz Taylor.^[3] Parke-Taylor amplitudes represent a new approach to computing scattering amplitudes in quantum chromodynamics using symmetry methods such as supersymmetry. Parke is also an expert on neutrino physics^[4] as well as the physics of the top quark.^{[citation needed]}
