Dr. Thejesh N. Bandi is an associate professor at the University of Alabama (UA) and the principal investigator of the Quantime Lab at UA. With two decades of experiences in high-end oscillators, atomic clocks, satellite navigation and timescale generation, Dr.Bandi has designed, developed, and qualified precision atomic clocks for ground and space navigation missions – the recent being successful first ever Indian Rubidium clock onboard NavIC constellation which he led the design and development at the Indian Space Research Organisation (ISRO). Dr. Bandi has a PhD from the University of Neuchâtel, Switzerland, and was a postdoctoral fellow at NASA’s Jet Propulsion Lab/Caltech, and Head of the clocks division at the ISRO. Dr. Bandi is a senior IEEE member and an active member of the Institute of Navigation. He is also life member of the American Physical Society and Optica. His research interests span from basic atomic and ion spectroscopy to its novel implementation methods with the atomic and optical clocks; quantum metrological studies; time scales and synchronization schemes; and Machine Learning methods for time and frequency metrology and safe and alternate GNSS. Dr. Bandi is also active in training the next-generation skilled manpower for the sustenance and growth of the PNT field.
