Ph.D. Thesis

I completed my Ph.D. in February 2012 at the Australian National University's Mount Stromlo Observatory, under the supervision of Profs. Michael Bessell and Warrick Lawson (UNSW). My thesis was entitled 'Revealing the Chamaeleon: Young, low-mass stars surrounding η and ε Chamaeleontis'.
