Karen Grutter

Karen Grutter is an NRC Postdoctoral Researcher in the Nanofabrication Research Group. She received a B.S. in Engineering Physics from Case Western Reserve University and a Ph.D. in Electrical Engineering and Computer Sciences from the University of California, Berkeley. For her doctoral research, she designed, fabricated, and characterized optical whispering-gallery mode resonators for use in optomechanical reference oscillators and photonic integrated circuits. Karen is working with Kartik Srinivasan developing techniques for adding on-chip tunability to cavity optomechanical systems for applications in signal manipulation and sensing.
