Research

I am currently a researcher in the Hersam research group at Northwestern University. My Ph.D. work focuses on fabricating electronic devices from solution-processed nanomaterials. In particular, I work with 2D materials, a class of nanomaterials with a wide range of optical and electronic properties. 2D materials can easily be paired together through printing techniques to produce a wide range of common electronic devices, such as thin film transistors, photodetectors, and electrochemical sensors.
