Associate Professor, Astronomy & Astrophysics, Australian National University
My research interests include: wide-field sky surveys, object classification and photometric redshift estimation; growth of supermassive black holes, early universe and variability; optical counterparts to gravitational-wave events; galaxy evolution through cosmic epochs and via environmental influence; dust in the Milky Way and star-forming galaxies.
