Hi, I am John and I am a Ph.D. student at the University of Crete (Department of Physics), under the supervision of assistant Professor Kostas Tassis. I am currently occupied in the astronomical instrumentation of the WALOP instrument for the Pasiphae Project, developed in IUCAA, under Professor A. N. Ramaprakash. In the past I have worked in optics, electronics, observational astrophysics and supernova remnants. In this website you can check my CV, as well as my past and current projects.
