Abraham's career has been notable for his contributions via non-parametric statistics to galaxy morphological classification, especially at high-redshift and early work on the Hubble Deep Field.[2] He was one of the leaders of the "Gemini Deep Deep Survey"[3] which led to several notable results on early galaxies including the evolution of elliptical galaxies and why a lot of them appear so remarkably old.[4] In 2011 Abraham won the P.G. Martin award
