Krishnan Thyagarajan

Senior Manager/ Associate Director, Hardware Research and Technology Lab, Future Concepts Division

Krishnan leads the cross-disciplinary Sensors, Devices and Systems (SDS) group that covers various aspects of sensing technologies ranging from sensing to making sense in the domains of energy, infrastructure protection, healthcare, and manufacturing. The SDS area is a diverse group of scientists and engineers, with their work funded both by federal agencies (DARPA, NIH, ARPA-E, DOE, DTRA) and commercial partners, and aims to deliver on novel science and technology directly impacting society. The horizon that the group is seeking to expand towards includes smart sensors, energy and material supply resilience, patient-centered diagnostics, hardware security (classical and quantum), and scalable optoelectronic manufacturing technologies.

Krishnan was a Swiss National Science Foundation Fellow at the Thomas J. Watson Lab of Applied Physics and the Kavli Nanoscience Institute at Caltech, Pasadena. There, funded by AFOSR, ONR, DOE, SNSF, Samsung, and Sony, he worked on metamaterials, metasurfaces, quantum nanophotonics, and set a record for the world’s first attojoule plasmonic optical modulator. Krishnan obtained his Ph.D. and M.S. in Applied Physics and Photonics from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland and a B.S. with honors in Physics from the University of Delhi, India. He has authored more than 40 publications, and 25 patents and is the co-founder of a PARC spin-off company for electromagnetic supercooling (EverCase Inc.).
