Short CV
I am currently a tenured senior researcher and Group Leader in the Theory Division at the Max Planck Institute of Quantum Optics. My current research focusses on the theoretical quantum information and quantum science, with an emphasis on the role of decoherence in many-body quantum systems. I am an engineer by training and I research topics in physics - my work often lies at the inter-disciplinary boundary of physics and technology.
I was previously an assistant professor (Tenure track) of Electrical and Computer Engineering (ECE) at the University of Washington (Seattle). I obtained my PhD and MS in Electrical Engineering from Stanford University, and my undergraduate also in Electrical Engineering from the Indian Institute of Technology (Delhi).
