Project Leaders

Olivier Parcollet, Ph.D.

Senior Research Scientist, CCQ

Olivier Parcollet joined the Flatiron Institute in 2018. His research focuses on the physics of quantum materials where strong electron-electron interactions lead to remarkable physical properties, as seen for example in the high-temperature cuprate superconductors.

Hao Shi, Ph.D.

Flatiron Research Fellow, CCQ

Hao Shi joined the foundation in 2017 as a Flatiron research fellow at the Center for Computational Quantum Physics. Previously, Shi was a graduate student at the College of William and Mary, where he earned his Ph.D. in computational physics. His research focuses on the…
