Areas of Expertise
Professor Tillers is a reviser of John Henry Wigmore's multi-volume treatise on the law of evidence and has published a variety of articles on evidence, inference, and investigation. He is an editor of the Oxford journal Law, Probability and Risk. He is former chairman and secretary of the Evidence Section of the Association of American Law Schools. He was a fellow of Law & Humanities at Harvard University and an Alexander von Humboldt & Senior Max Rheinstein Fellow at the University of Munich. Professor Tillers was a visiting professor at Harvard Law School in the spring semester of 2002, and legal adviser for the Latvian mission to the United Nations during the 48th Session of the General Assembly. He maintains a website with discussion of a wide range of general issues of evidence.
Professor Tillers' scholarship focuses on evidential inference and fact investigation in legal settings. He maintains that multiple methods of marshaling and analyzing evidence are important in trials, in pretrial investigation and informal fact discovery, and in other domains. He believes that inference networks offer a useful window into investigative discovery and proof at trial. But he believes that subjective, synthetic, and gestalt-like perspectives on evidence, inference, and proof are also essential.
Professor Tillers was born in Riga, Latvia, in 1943. He arrived in the United States in 1950.
