Peter Day
Senior Research Scientist

Peter Day is a Microdevice Engineer at JPL and holds a visiting associate position at Caltech. He received a Bachelor’s degree in Physics from the University of California, Berkeley, and a PhD in Physics from Caltech where he studied phase transitions in thin films. He received an Alexander von Humbolt fellowship with which he investigated helium atom scattering from surfaces at the Max Plank Institute for Fluid Dynamics in Goettingen, Germany. He began at JPL preparing critical phenomena experiments for flight aboard the space shuttle and international space station. For the last 12 years he has worked at the Microdevices Lab at JPL developing new detector and amplifier technologies.
