Stefany Cruz

Hi! My name is Stefany Cruz and I am a Ph.D. student in Computer Engineering at Northwestern University. I work in the Ka MoaMoa lab, where I am advised by Josiah Hester. I obtained my B.S. in Electrical Engineering from the University of California, Riverside (UCR) in 2019 where I performed undergraduate research in Dr. Grover’s TEC Lab and Dr. Wei Ren’s  Cooperative Vehicle Networks (COVEN) Lab. Prior to UCR, I attended Pasadena City College where I received my A.S. degrees in Mathematics and Physics, and A.A’s in Engineering Technology and Natural Science.

My research interests are in building, designing, programming, and deploying battery-free, intermittently powered devices in the sustainable Internet-of-Things. My goal is to develop and deploy interactive high performance applications running on frequently failing battery-free smart devices to extend and augment the capabilities of the human experience across disciplines in health, space, and in resource constraint communities.
