Prof. Dr. Ulf-Dietrich Reips is a full professor in the Faculty of Sciences at the University of Konstanz, where he holds the Chair for Psychological Methods, Assessment, and iScience. Between 2009 and 2013 he was a full-time tenured IKERBASQUE research professor at University of Deusto in Bilbao, Spain, and remains affiliated with Ikerbasque. Until 2009 he was an assistant professor and lecturer ('Oberassistent') at the Psychology Department of the University of Zurich, Switzerland. He received his PhD in 1997 and his habilitation (venia legendi, title 'Privatdozent') in 2004 from the University of Tübingen, Germany. In 1992, he received an M.A. in Psychology from Sonoma State University, California. Reips spent most of his undergraduate and graduate years at the University of Tübingen, where he had attended the Leibniz Kolleg. He majored in both Psychology and General Rhetoric (as a student of Walter Jens) and had a minor in Political Science. In 2012, Ulf-Dietrich Reips received a FIRST award from University of Colorado Boulder and is since affiliated on an honorable basis with its Department of Psychology and Neuroscience. Based on his publications' impact and his affiliation with IKERBASQUE, the Consejo Superior de Investigaciones Cientificas, Spain, ranked him 7th of "Top Scientists working at Spanish Private Universities" in 2014. In Fall 2015, Reips was offered to direct the Leibniz Institute for Psychology Information in Trier, in association with a full professorship for Psychology at University of Trier.
Ulf-Dietrich Reips is working on Internet-based research methodologies (or iScience, Internet science, online research methods), in particular Internet-based psychological experimenting (a method used in experimental psychology) and Internet-based tests, the psychology of the Internet, measurement, the cognition of causality, Social Media, and Big Data. In 1994 and 1995 he founded the Web Experimental Psychology Lab, the first laboratory for conducting real experiments on the World Wide Web. In 1997, he was one of the seven founders of the German Society for Online Research (DGOF) and wrote a book chapter on the methodology of conducting experiments via the Internet  that later won him a young scientist award by the German Society for Psychology. His 2002 article in the journal "Experimental Psychology", Standards for Internet-based experimenting, defined the field and became its journal's most cited article. In 2005, Reips was elected the first non-North American president of the Society for Computers in Psychology (SCiP).
Ulf-Dietrich Reips and his Web services have received numerous awards, from institutions including the Methods Division of the German Psychological Society (young scientist award, 1997), Oxford University ("key player in the social shaping of e-science and e-social science"), University of Colorado Boulder, Ben Gurion University of the Negev, Encyclopædia Britannica, Der Spiegel, “Planet Science”, Bild der Wissenschaft, New Scientist, The British Academy, Die Zeit, IBM, the American Psychological Society, and others. In January 2017 the Society for Computers in Psychology named the 2001 paper "Reips, U.-D. (2001). The Web Experimental Psychology Lab: Five years of data collection on the Internet. Behavior Research Methods, Instruments, & Computers, 33, 201-211." one of eight "groundbreaking and influential" articles in the history of the society and the field.
In 1996 Ulf-Dietrich Reips won in the First Internet Literature competition in Germany, co-organized by the German weekly Die Zeit and IBM with his digital poem "Das Websonett", a digital media variation and sonetto di risposta on A.W. Schlegel's "Das Sonett". Literature theorist Erika Greber described the Websonett as "literarisch anspruchsvoll" (literarily sophisticated) and featured a special printable version Reips created on the last page of her compendium on poetological metaphorism and literature theory. Reips later created a technically updated version, even though all versions remain fully functional in modern web browsers.
