In 2014, Prof. Matthew Dickerson completed his 25th year as a member of the computer science department at Middlebury College. He earned a BA from Dartmouth College in 1985 and PhD in Computer Science from Cornell University, and was the first faculty member with a Ph.D. in computer science hired by the college. During his 25 years at the college he has received more than ten federal funded research grants including grants through the National Academy of Sciences, NATO, and various NSF programs. His primary research area  has been algorithms and data structures for geometric, geographic, and spatial computing—an area known as computational geometry in which he is internationally known for his work on Voronoi diagrams. He has also done research and published several papers on computer science education, and is in the final year of an NSF grant exploring the use of agent-based modeling in the introductory computer science curriculum. Currently, Professor Dickerson is working on a research project on spatially explicit agent-based modeling of killer whales in southeast Alaska in collaboration with biologists and computer scientists at the NOAA and the University of Alaska.

Prof. Dickerson also did graduate work in Old English Language and Literature and has  published several books including a recent medieval historical novel titled The Rood and the Torc, set in mid 7th century Europe. He is an internationally known scholar on the works of J.R.R.Tolkien with four published books about Tolkien as well as book chapters on Tolkien in five other volumes. 

Computer Science Research

Matthew Dickerson's primary areas of research in computer science are:

  • Algorithms and Data Structures for Computational Geometry
  • Individual-based Modeling and Multi-agent Simulation in Ecology
  • Computer Science Education
  • Geographic Information Systems

Perhaps a broader category describing Dickerson's research interest in spatial computation, which includes geometric and geographic computation, as well as many types of modeling that explicit represent space or "environment". Since coming to Middlebury College, he has published more than 40 papers and videos, and received 9 federal funded grants for his research in computational geometry. His work on Voronoi Diagrams and the Minimum Weight Triangulation is internationally known. He has also served as national president of CCSC (Consortium of Computing Sciences in Colleges) as well as a regional board member of the Northeast CCSC (CCSCNE). He has published several articles and videos on computer science education.

Writing and Literature

Matthew Dickerson has also continued his research and writing about literature, with a special interest in environmental literature and nature writing, and in mythopoeic literature (especially that of J.R.R.Tolkien and C.S.Lewis). He is also an internationally known Tolkien scholar. He has published several books about literature, including: Ents, Elves and Eriador: the Environmental Vision of J.R.R.Tolkien (with Jonathan Evans, University Press of Kentucky, 2006) and Narnia and the Fields of Arbol: the Environmental Vision of C.S.Lewis (with David O'Hara, University Press of Kentucky, 2009) which bring together his interests in environmental and mythopoeic literature. His other titles include:

  • From Homer to Harry Potter: a Handbook of Myth and Fantasy (Brazos Press, 2006)
  • Following Gandalf: Epic Battles and Moral Victory in the Lord of the Rings (Brazos Press, 2004)
  • Hammers and Nails: the Life and Music of Mark Heard (Cornerstone Press, 2004)
  • The Finnsburg Encounter (Crossway Books, 1991)

CSCI 0190 - Computer Models & Simulation      

Computer Models and Multi-Agent Simulation
In this course we will explore agent-based computer models and simulations as a means of studying phenomena from both biological and social sciences. Agent-based simulation will then be used as a basis for introducing individual-based modeling and complex adaptive systems. A significant amount of time will be spent teaching the NetLogo programming language as a software tool for developing simulations. We will also introduce some of the important topics in the discipline of computer science, including algorithmic reasoning and data abstraction. No prior experience in programming is assumed. This course counts as an environmental studies lab science cognate. 3 hrs. lect./lab

FYSE 1363 - Humans, Computers, & Souls      

Humans, Computers, and Souls
In this seminar we will contrast two philosophies of human nature, known as physicalism and integrative dualism. The physicalist view, represented by noted figures such as philosopher Daniel Dennett and biologist Richard Dawkins, understands humans as complex biochemical computers whose minds are reducible to physical brains. A competing view, referred to by philosopher Charles Taliafero as “integrative dualism”, sees humans as both spiritual and physical beings. We will touch on philosophy of computation, philosophy of mind, philosophy of science, and philosophy of soul, with readings from Dennett, Dawkins, Taliafero, and also Raymond Kurzweil, C.S.Lewis, and others. 3 hrs. sem.

INTD 1059 - Tolkien's Middle-Earth      

Exploring Tolkien's Middle-Earth
In a long letter to his publisher describing his Middle-earth writings, J.R.R.Tolkien once wrote, “I had a mind to make a body of more or less connected legend, ranging from the large and cosmogonic, to the level of romantic fair-story—the larger founded on the lesser in contact with the earth, the lesser drawing splendour from the vast backclothes.” In this course we will explore how Tolkien achieved this, looking at the ideas and relationships running between his romantic fairy-story (The Hobbit), his heroic romance (The Lord of the Rings), and his cosmogonic myth (The Silmarillion).
