Overview
Christina is interested in applying nanofabrication
techniques to control the properties of materials as well as use this precise
control of materials and their properties to help researchers solve challenging
nanoscale scientific problems in areas ranging from medicine and biology to
chemistry, physics, engineering, and beyond. She has experience with
lithography, thin film deposition, active plasmonics, optical spectroscopy, and
using scanning probe microscopy (AFM/KPFM/EFM) to probe 2D material, organic
semiconductor, and quantum dot field effect transistors. In VINSE, Christina
manages and trains users as well as Tech Crew members on the Angstrom Multimode
and Resistive deposition systems, tube furnaces, electrical probe station,
Raith EBL, Heidelberg laser writer, and 3D printers. She additionally
developed and leads workshops on microfluidic device fabrication.
Christina also leads the facilitation of cleanroom teaching and outreach in
VINSE including microfluidics, solar cells, and 2D materials.
