Fundamental science and real-world applications of ambient Tip-enhanced Stimulated Raman studies in time and frequency domain.

My research combines scanning tunneling microscopy with optical spectroscopic techniques to query, in real-time, individual molecules with atomic spatial resolution.

I am developing Stimulated Raman scattering (SRS) based methods to improve the Raman yield of a functionalized scanning probe microscope tip.  Also interested in surface enhanced Raman scattering (SERS) based methods to probe and visualize individual molecules.

Will fabricate silver tips for tip-enhanced Raman spectroscopy experiments and image their properties through scanning electron microscopy.

My research interests involves studying charge trasnport at single molecule level using Scanning probe microscopy techniques (mainly Scanning Tunneling Microscopy (STM) at room temperature, in situ and under electrochemical potential control).  Currently I am investigating the applications of STM-Tip enhanced Raman Spectroscopy in DNA sequencing.

Studying photo-induced force microscopy, with ultrafast optical microscopy.
