Narsireddy Anugu earned his Ph.D. by involving in the successful development of VLTI/GRAVITY in 2017 working in Portugal. GRAVITY has produced several interesting science results including the black hole at the center of our Galactic Center. After his Ph.D., he joined as a postdoctoral fellow at the University of Exeter, UK, and University of Michigan. Being part of this group, Anugu played an important role in the sensitivity upgrade of MIRC and involved in the development of MYSTIC and CHARA adaptive optics instruments. These efforts aimed at observing discs around faint young stellar objects with near-infrared interferometry.
