Research interests
My research interests focus on the interface between observational extragalactic stellar astronomy and star formation. I am a pioneer in the study of extragalactic pre-main-sequence (PMS) stellar populations, being one of the first to investigate the sub-solar PMS stellar content of star-forming regions in the Magellanic Clouds with the Hubble Space Telescope. A major part of my research focuses also on the investigation of structure in astronomy. I have pioneered the study of the formation and evolution of stellar structures through the application of stellar clustering analysis across a wide range of time- and length-scales. My expertise includes computational and statistical methods, which I employ with the implementation of machine learning algorithms, designed for classification, regression, and clustering, and the application of deep learning techniques by designing and training neural networks. I currently lead a group of one Ph.D., two MSc, and one BSc students, working on machine learning applications for astronomy.
