Peskin has been recognized for his work in proposing and analyzing unifying models of elementary particles and forces in theoretical elementary particle physics, and proposing experimental methods for testing such models.^[3][4] Peskin was elected to the American Academy of Arts and Sciences in 2000.^[3] He was appointed a co-editor of the journal Annual Review of Nuclear and Particle Science as of 2023.^[5]

Michael Peskin is a fourth generation descendent of Jewish Lithuanian emigrants from the Pale of Settlement. Both of his parents became medical doctors. Peskin attended Lower Merion High School in the Philadelphia area and later New Trier West in the Chicago suburbs.^[6]

Peskin was an undergraduate at Harvard University. He obtained his Ph.D. in 1978 at Cornell University studying under Kenneth Wilson. He was a junior fellow at the Harvard Society of Fellows from 1977–1980.^[6]

After receiving his Ph.D. from Cornell University, Peskin served as a junior fellow of the Harvard Society of Fellows from 1977 to 1980. ^[7] He also held postdoctoral appointments at Saclay Nuclear Research Centre (1979–1980) and Cornell (1980–1982).^[8][6] In 1982, Peskin joined the faculty of the SLAC National Accelerator Laboratory at Stanford University.^[9]

In 2000, Peskin was elected to the American Academy of Arts and Sciences.^[3] He was appointed a co-editor of the journal Annual Review of Nuclear and Particle Science as of 2023.^[5]

Peskin has worked on many aspects of quantum field theory and elementary particle physics, exploring and going beyond the Standard Model of particle physics to explore technicolor theories.^[10] Peskin and Schroeder's widely used textbook on quantum field theory, An Introduction to Quantum Field Theory (1995, 2018) is considered a classic in the field.^[11][12][13] More recently, he has written Concepts of Elementary Particle Physics (2019), a textbook on the Standard Model.^[14]

In 1990, Peskin and Tatsu Takeuchi proposed the parameterization of a set of three measurable quantities, called S, T, and U, that are used to describe and simplify precision electroweak fits. These parameters are sensitive to new physics which contributes to oblique corrections.^{[15][16][17][18]} They are now called the Peskin–Takeuchi parameters.^[19]

Peskin uses high energy colliders to search for new physical interactions on the basis of high-precision observations and measurements of elementary particles, including the W and Z bosons, the top quark, and the Higgs boson.^{[20][21][22][23]} He is interested in modelling dark matter^[24] and is a noted advocate of building a future linear collider,^[25][23] a “Higgs factory”.^[1]
