Martin Philip Head-Gordon (né Martin Philip Head) FRS is a professor of chemistry at the University of California, Berkeley, and Lawrence Berkeley National Laboratory working in the area of computational quantum chemistry.^[2] He is a member of the International Academy of Quantum Molecular Science.^[3][1][2]

A native of Australia, Head-Gordon received his Bachelor of Science and Master of Science degrees from Monash University,^[when?] followed by a PhD from Carnegie Mellon University^[3] working under the supervision of John Pople developing a number of useful techniques including the Head-Gordon-Pople scheme for the evaluation of integrals,^[4] and the orbital rotation picture of orbital optimization.

At Berkeley,^[5] Martin supervises a group interested in pairing methods, local correlation methods, dual-basis methods, scaled MP2 methods, new efficient algorithms, and very recently corrections to the Kohn-Sham density functional framework. Broadly speaking, wavefunction based methods are the focus of his research. Head-Gordon is one of the founders of Q-Chem Inc.^{[citation needed]}
