Mattias Fitzpatrick

Assistant Professor of Engineering

(Starting July, 2022)

Adjunct Professor of Physics

Heptagon Kagome Device

Hyperbolic lattice formed from a set of coupled superconducting coplanar waveguide cavities.


Mattias Fitzpatrick graduated with a bachelor's in physics and mathematics from Middlebury College, and a PhD in electrical engineering (applied physics) from Princeton University where he worked with Professor Andrew Houck on superconducting circuits. He then received an Intelligence Community (IC) postdoctoral fellowship to work on quantum sensing in the lab of Nathalie de Leon at Princeton University. After his postdoctoral fellowship, he went on to work on quantum computation at IBM's Thomas J. Watson Research Center. His current research focuses on quantum engineering and quantum sensing using superconducting circuits. Outside of the lab and classroom he enjoys cooking, backpacking, playing soccer, skiing, and generally spending time in the great outdoors.
