At Clarkson, I have enjoyed the opportunity to teach a wide variety of courses from operating systems to networks to security. Wherever possible, I mix lecture with hands-on lab experiences, especially using open source software tools. Open source tools form a toolkit that students can take with them to any job or to the forming of new businesses. I want to give students tools and strategies for questioning what we think we know about the best way to build the computing systems that are changing nearly every aspect of modern life. I ask students to go beyond the course material to solve open-ended problems. I ask them to practice strategies for life-long learning by engaging with primary sources of information. I set current systems in the context of how and why they developed as they did and encourage students to question whether the underlying assumptions are still valid today. I ask them to consider whether the systems we are building and using respect the rights of individuals and contribute to healthy sustainable communities. One of my most popular ACM Distinguished Speaker Lectures (“Becoming a Researcher: Tools and Strategies for Taming the Angst and Changing the World”) is based on experience I have had teaching students at all levels to tackle open-ended problems. Beyond my regular teaching contributions, I have taught several study abroad programs including a service learning course to the Dominican Republic (2017 and 2015), a global business program course to Brazil (2014) and a course on the origins of mathematics jointly with SUNY Potsdam faculty to Mexico (2013).
