Dhanushka Amaradasa is a Researcher at the Department of Physics University of Ruhuna ,Sri Lanka.He earned his B.Sc. degree in 2014,and initiated a research on astronomy instrumentation in 2015 . He completed his Master of Philosophy degree in Astronomy Instrumentation in 2021,thesis titled “Establishment of a wide field telescopic system for observing Near-Earth Objects (NEO) entering Sri Lankan sky” where he designed and developed an autonomous all-sky camera network and a wide-field telescope system for detecting fast optical transients. Fabrication of aspheric telescope optics, designing of High-Vacuum optical coating system, and embedded system for all-sky monitoring were some of the main outcomes of his research work. The all-sky camera network he made served as the first meteor detection network in Sri Lanka and generated several patanable products.His research field includes observational astronomy, planetary sciences,digital signal processing, optics and photonics , vacuum engineering, additive manufacturing, computer-aided design and simulation,microcontrollers and embedded systems.He was a finalist of the 2018 Three Minute Thesis Competition organized by the Sri Lanka Young Scientist forum and a active astronomy communicator.Currently, he is serving as the National Outreach Coordinator for Sri Lanka, at the International Astronomical Union (IAU) in Office for Astronomy Outreach (OAO).
