Ewens received a B.A. (1958) and M.A. (1960) in Mathematical Statistics from the University of Melbourne, where he was a resident student at Trinity College,[2] and a Ph.D. from the Australian National University (1963) under P. A. P. Moran. He first joined the department of biology at the University of Pennsylvania in 1972, and in 2006 was named the Christopher H. Browne Distinguished Professor of Biology. Positions held include:
Prof. Ewens is a Fellow of the Royal Society and the Australian Academy of Science. He is also the recipient of the Australian Statistical Society's E.J. Pitman Medal (1996), and Oxford University's Weldon Memorial Prize. His teaching and mentoring at the University of Pennsylvania have also been recognized by awards.[citation needed]
Prof. Ewens also participates in the Genomics and Computational Biology (GCB) Ph.D. program of the University of Pennsylvania School of Medicine.
Since 2006, he has taught statistics at the University of Pennsylvania's Wharton School.
In 2022, Ewens was appointed Officer of the Order of Australia in the 2022 Queen's Birthday Honours for "distinguished service to biology and data science, to research, and to tertiary education".[3]
