Alison Sills
Professor, Physics & Astronomy

Dr Alison Sills studies weird stars in unusual places. The stars that interest her have had a strange encounter during their life, such as a collision with another star or an interaction with their binary companion. These events happen more often in dense stellar clusters. Dr Sills uses a variety of computational tools to model the formation and evolution of these clusters and their stellar populations. Dr Sills grew up in Toronto and attended the University of Western Ontario for her BSc before studying at Yale University for her PhD. After postdoctoral positions at The Ohio State University and the University of Leicester in the UK, she returned to Ontario to take up a faculty position at McMaster University in 2001. A full professor at McMaster since 2012, Dr Sills has also served as Associate Dean of Science and Associate Dean of Graduate Studies. She has published over 150 research papers with over 4000 citations, has supervised over 50 students & postdoctoral fellows, and has directly managed about $2M in research grants. Dr Sills is involved in the astronomical community at the national and international level, through her membership in Canadian Astronomical Society committees, the Canadian Institute for Theoretical Astrophysics council, SuperChair of the Canadian Telescope Time Allocation Committee, and a International Astronomical Union steering committee. She has reviewed grant, scholarship, and telescope time applications for granting agencies in half a dozen countries, and been involved with organization of 30 international conferences since 2000. Dr Sills also spends time on outreach activities to bring astronomy to the public, to support women in STEM, and to bring scientists to elementary schools.
