Aaron Halfaker (/ˈhæfeɪkər/; born December 27, 1983) is a principal applied scientist at Microsoft Research.^[1]^[7]^[2] He previously served as a research scientist at the Wikimedia Foundation until 2020.^[8]^[9]^[10]

Education

Halfaker earned a Bachelor of Science degree in computer science from the College of St. Scholastica in 2006, where he started off as a physical therapy major but switched to computer science after taking a programming class with Diana Johnson.^[11] He subsequently earned a PhD in computer science from the GroupLens Research lab at the University of Minnesota in 2013.^[3]

Career and research

Halfaker is known for his research on Wikipedia^[12]^[13] and the decrease in the number of active editors of the site.^[14]^[15]^[16] He has said in autumn 2013 that Wikipedia began a "decline phase" around 2007 and has continued to decline since then.^[17]^[18] Halfaker has also studied software agents (bots) on Wikipedia,^[19] and the way they affect new contributors to the site.^[8] While a graduate student he developed a tool for Wikipedia editing called Snuggle with Stuart Geiger. Snuggle tackles vandalism on Wikipedia and highlights constructive contributions by new editors.^[20]^[21] He has also built an artificial intelligence (AI) service called Objective Revision Evaluation Service (ORES) in 2015, used to identify vandalism on Wikipedia and distinguish it from good faith edits.^[22]^[23]
