Alan Robert Dennis, Baron of Cowie (born 1960) is a Canadian-American scientist specializing in Information Systems and nobleman in the Baronage of Scotland.^[1] He is a professor and holds the John T. Chambers Chair of Internet Systems at the Kelley School of Business, Indiana University.^[2]

Dennis earned his Bachelor of Computer Science from Acadia University in 1982, his MBA from Queen's University in 1984, and his PhD in Business Administration from the University of Arizona in 1991.^[3] He began his academic career as a professor at The University of Georgia and moved to Indiana University in 2000,^[4] where he continues to work as a leader in Information Systems research.

Dennis has authored over 150 research papers,^[5] chaired 16 dissertations, and co-authored four books. His research explores team collaboration, the spread of fake news on social media, cybersecurity, and artificial intelligence.^[6]

Dennis's research focuses on team collaboration, media synchronicity, the spread of fake news, and artificial intelligence.

Dennis is well-known as one of the early pioneers of research to support teams and groups, working under Prof. Jay Nunamaker at the University of Arizona from 1987-1991. He has published dozens of articles and conference papers on this topic and continues this research stream into the present day. Key papers include

One of his major contributions to Information Systems research was his work on media, including the debunking of Media Richness theory and the development of Media Synchronicity Theory:

Dennis was an early contributor to research on Fake News on social media, and continues this research today:

Dennis has a major research stream on conversational agents controlled by Artificial Intelligence (AI). This work focuses on text-based chatbots and more realistic digital humans:

Dennis has authored several influential books:

Business Data Communications and Networking (14th Edition)
Systems Analysis and Design (8th Edition)
Systems Analysis and Design: An Object-Oriented Approach with UML (6th Edition)
Networking in the Internet Age

Dennis was born and raised in Prince Edward Island, Canada. In 1978, he moved to Wolfville, Nova Scotia, to attend Acadia University, where he earned his Bachelor of Computer Science in 1982.^[7] He then moved to Queen’s University and received a Master of Business Administration in 1984.^[8]

From 1984 to 1987, he taught as a Lecturer at the Queen’s School of Business. Dennis moved to Tucson, Arizona, to pursue his PhD in Business Administration (specializing in Management Information Systems), which he earned in 1991 from the University of Arizona.^[9]

In 1991, Dennis joined the Terry College of Business at the University of Georgia as an Assistant Professor, later becoming Associate Professor in 1995 and Professor in 1999. In 2000, he moved to Indiana University’s Kelley School of Business, becoming the first John T. Chambers Chair of Internet Systems.^[10]

Dennis married Eileen Robichaud in 1982; they divorced in 2004.^[11] He married Kelley McNamara in 2010; they divorced in 2015.^[12] He received the title Baron of Cowie in 2020^[13] following the death of his father, G. Douglas Dennis.^[14][15] In 2022, he married DeVon Rightley-Tucker, Baroness of Cowie.^[16]

Dennis has one son, Alexander (Alec) Dennis, Younger of Cowie (born 1993),^[17] who is an Assistant Professor of Information Systems at Iowa State University.^[18]

Dennis has received numerous awards for research, teaching, and service.^[19] The most notable include:

• AIS Fellow (2012): Recognized by the Association for Information Systems (AIS) for significant global contributions to Information Systems.^[20]
• LEO Award (2021): Recognized for lifetime exceptional achievement in Information Systems, named for the world's first business computer (Lyons Electronic Office).^[21]
• Dennis was ranked among the top 1% of the most influential researchers globally across all scientific disciplines in 2021.^[22][23]
