About

I am a researcher at KTH Royal Institute of Technology, a Research Scientist at IBM Quantum currently on sabbatical, and a Visiting Scientist at the RIKEN Center for Quantum Computing. My core expertise is Quantum Signal and Information Processing, with research spanning quantum information and learning theory, near-term quantum algorithms for noisy hardware, Hamiltonian simulation, functional approximation and encoding, open-system dynamics, and applications across quantum physics and chemistry, biology, communication theory, sensing, and signal processing. I received my M.S. and Ph.D. from IIT Kharagpur, where I was a Prime Minister's Research Fellow.
