Community Work and Service

Wisbey recently completed a postdoctoral fellowship at the National Institute of Standards and Technology in Boulder, Colorado before becoming an assistant professor at Saint Louis University. Currently,  Wisbey is in the process of completing his lab which will include an adiabatic demagnetization refrigerator (ADR) and sputter deposition system. This will allow Wisbey to explore new dielectric materials and metals for use in superconducting circuits.
