Zack Geballe

Zack Geballe is a Senior X-ray Physicist at Sigray, Inc. since June 2025, with a rich background in high-pressure physics. Previously, Zack served as a Research Scientist at Carnegie Science from October 2014 to June 2025, where leadership was demonstrated through the development of a pioneering high-pressure “exploding wire” experimental platform. This role involved driving both engineering and scientific advancements, particularly in microfabrication and optical temperature measurement techniques. Additionally, multiple postdoctoral fellowships were completed in high-pressure research, leading to significant discoveries such as lanthanum superhydride, the highest temperature superconductor to date. Zack's initial research training was at UC Berkeley, culminating in a Ph.D. in Mineral Physics, while also earning a BS in Physics with a minor in Mathematics from the University of Michigan.
