Sandor Kruk - Personal Profiles
Main Research Fields
My scientific interests lie in the formation and evolution of galaxies through cosmic time and my research is focused on measuring the morphology of galaxies and the exploration of large datasets. I use crowdsourcing projects such as Galaxy Zoo to visually classify galaxies as well as quantitative measures such as bulge-bar-disc decompositions in multi-wavelength data. I am interested in the dynamical processes that lead to the formation of galaxy structure, and their subsequent role in shaping galaxies. With the upcoming ESA Euclid mission, I plan to measure these structures and study their redshift evolution.
I am also interested in mining data archives, such as the ESA science archives, using citizen science and machine learning, being the PI of the Hubble Asteroid Hunter (www.asteroidhunter.org), a citizen science project asking members of the public to identify asteroids in the Hubble archives. Check out these articles: Foreground asteroid passing the Crab Nebula, Galaxies – with a chance of asteroids, Citizen scientists find asteroids in Hubble images and Hubble's celestial peanut.
Being passionate about education and increasing the access of young people to science education, I initiated three large projects: Romanian Science Festival, the British Astronomy and Astrophysics Olympiad, and the Oxford for Romania Summer school, reaching thousands of students every year.
