Biography
Ph.D. Candidate, Mechanical Science and Engineering
Education:
B.S. in Mechanical Engineering from The University of Texas at Austin, 2018
I graduated from The University of Texas at Austin in May 2018 with a B.S. in Mechanical Engineering, and am now in my sixth year of Ph.D. studies here in the Mechanical Science and Engineering Department at UIUC. I was formerly advised by Prof. SungWoo Nam until he moved to UC Irvine in 2021 and I then joined HDCL.
Past Projects: Kirigami Graphene
My previous work in Prof. Nam’s lab focused on applying kirigami (i.e. cut paper) patterning to impart greater stretchability and flexibility to graphene-based wearable sensors by transforming in-plane strain into out-of-plane bending. Typical chemical vapor deposition (CVD) -grown graphene can only reversibly withstand strain up to 6.5%, but the kirigami-patterned graphene electrodes and sensors we developed were capable of reversibly withstanding uniaxial >240% over many cycles with negligible performance change. This work was then extended to the development of multiaxially stretchable krigami-graphene devices functionalized for sensing multiple different biosignals
Current Project: Pectin-Graphene Composite Temperature Sensors
My current work focuses on the development of pectin-graphene composite materials for transparent, biocompatible, wearable, and extremely sensitive temperature sensors.
