I am an experimental condensed matter physicist. My primary research interest is looking into the fundamental aspects of how carrier dynamics evolve in two dimensional electronic systems, primarily graphene, a single sheet of carbon atoms. The apparent ease with which average carrier concentration can be tuned in these systems is accompanied with its own set of complications; for example being sensitive to practically any voltage source in its immediate environment. The result is charge disorder which can have important consequences in carrier transport.

In order to gain maximum insight, I design experiments combining standard transport measurements with scanning probe techniques like STM, AFM, EFM and KPFM. The experimental conditions can range from ambient room temperature to extreme cases such as intense magnetic fields up to 14 T or under ultra high vacuum and at temperatures down to few hundred milli Kelvin.

Having fabricated most of the devices that I measured as well as the scanning probes for combined AFM/STM, I am well acquainted with standard nano-fabrication techniques.

I thoroughly enjoy programming and data analysis and love to teach and guide others.
