My Saint Michael's:

I came to Saint Michael's College when the Computer Science department began back in 1982. I use my computer (which is not just for e-mail and searching the Web!) as a tool to solve problems that involve a significant amount of tedious calculations. Many of these problems require a mathematical model to simulate inside the computer what is happening in the real world. The computer can then be used to evaluate these "virtual worlds", and examine their ability to predict the future. The computer can also be used to help determine how realistic these models are in relation to our own physical world. In my classes, if I see that some topics are very difficult for students to learn, I try to develop some pedagogical tools to aid in their understanding, and if these are successful, I then share them with colleagues at other institutions.

Because my classes have fewer than 15 students in them, I really get to know the students fairly well each semester, and therefore, I can give them more individual help (if they need it) than if I were teaching much larger classes. The atmosphere in the classroom is also less formal, which hopefully encourages the students to feel more relaxed and comfortable asking questions or putting forth their ideas during class.

Research Interests:

Simulation and predictive modeling; minimal perfect hashing functions; computer science education, concurrent programming using semaphores; Sidon set discovery; the MIPS architecture, analysis of algorithms' and cryptography.

My Saint Michael's:

I appreciate the willingness of students at Saint Michael’s to work hard in classes that challenge their abilities, the esprit de corps with their fellow classmates, their overall appreciation for taking advantage of the significant opportunity of being enrolled in an institution of higher learning for four years, their respect for the faculty, and their investment in becoming intellectually enriched individuals.

I especially enjoy teaching the two course sequence that our Computer Science majors typically take during their junior year (Operating Systems in the fall, and Computer Architecture in the spring). This is mainly due to the fact that after establishing a firm foundation concerning the ideas behind developing software in their first four computer science courses, these two courses really allow for a very detailed study of how Operating Systems work, and what the hardware must do to execute software efficiently. I have recently begun teaching a course in cryptography and computer security, and have found this to be very interesting as well.

In the Computer Science Department, we really get to know our students, and vice versa. If a student gets excited about a specific topic in a class, that student has the opportunity to do some research with that professor under the "CS411 umbrella" in a later semester. Our Linux lab also provides our majors/minors with experience using another platform (besides the MS Windows operating system.)

Life Off Campus:

Hiking, cross country skiing, and biking are some of the ways I stay active when I’m not on campus. I also enjoy watching (and predicting) sport events; reading science fiction; and playing board games like Scrabble, Bohnanza, Rail Baron, Chess, and Backgammon.
