Sekazi Kauze Mtingwa:[1] (born Michael Von Sawyer;[2] October 20, 1949) is an American theoretical high-energy physicist.

[10] The title of his PhD thesis is "Asymptotic chiral invariance and its consequences,"[11] which he completed under the supervision of Curtis Callan.

[2] After graduating from Princeton, Mtingwa took a research associate position, which turned into a part-time assistant professorship including some teaching duties, from Susumu Okubo at the University of Rochester.

Mtingwa received a Ford Foundation fellowship in 1980 and took it to Fermilab in Illinois for a one-year postdoctoral position, and became a research physicist there in 1981.

[12][13] [14] For this work, he was awarded the 2017 Robert R. Wilson Prize for Achievement in the Physics of Particle Accelerators,[3] since that theory "empowered major discoveries in a broad range of disciplines by a wide variety of accelerators, including hadron colliders, damping rings/linear colliders, and low emittance synchrotron light sources.

"[3] While at Fermilab, he also contributed in a significant way to two of the antiproton source accelerator systems,[15] which were instrumental in particle discoveries, including that of the top quark.

In 1988–1991, Mtingwa worked at Argonne National Laboratory, where he developed theory of advanced wakefield and plasma acceleration [16] and of the photon colliders.
