My laboratory efforts are mainly devoted to measuring and understanding the fascinating phenomena that arise when nano-devices are coupled to a variety of materials, or to other nano-devices. Utilizing cleanroom fabrication techniques, nano-circuits separated by only a few tens of nanometers are fabricated and characterized at cryogenic temperatures using techniques such as resonant tunneling and Coulomb drag.
I am especially interested in experimentally characterizing the strong electron-electron interactions arising in the one-dimensional Luttinger liquid regime, and in studying Majorana zero modes present in hybrid superconductor-semiconductor low-dimensional devices.
