Shyamprasad Natarajan Raja

Shyam is a researcher at the Department of Micro and Nanosystems at KTH. He is developing solid-state nanogap and nanopore platforms for single molecule sensing applications.

Short CV

Shyam obtained his bachelor’s degree in mechanical engineering at IIT Madras in India, and his master's and doctoral degrees from ETH Zurich in Switzerland. He experimentally studied phonon transport in low-dimensional materials such as semiconducting nanowires and graphene during his doctoral studies at ETH Zurich. His research interests include nanomaterials, nanofabrication, energy conversion and transport phenomena across scales and sensing technologies.
