Research Interests

Our group is interested in developing new tools to fabricate devices and perform chemical analysis at the microscale.
 

Specific Projects

1) We are improving the resolution of direct laser writing (DLW) lithography using a 405 nm laser by using chemical additives and also by incorporating a second near-IR laser. 
2) We are investigating the use of DLW to pattern the electrochemical growth of metals. 
3) We are combining DLW and conventional lithography to take advantage of their benefits while minimizing the shortcomings of each.
