Recently, Shravan Raghunathan has started as a new PhD student at COPS. Previously Shravan worked at the Indian Institute of Technology-Madras, India, on generating light beams carrying Orbital Angular momentum implemented by computer generated holography as well as on static light-scattering measurements to obtain particle size distributions using low cost techniques. He will now work on Free-form scattering optics under the supervision of Prof. Willem Vos.
