I consider teaching and mentorship vital to my role as a professor. Students provide fresh perspectives and challenge me to think differently about the world and my work. You can read more about my teaching philosophy here.

CMSC434 - Introduction to Human-Computer Interaction

Course Description
This is the only course in the undergrad computer science catalog with the word human in its title. This is not insignificant. In this course we will reposition ourselves to think about computer science not just in terms of algorithmic performance and technical sophistication but in terms of how technology can be perceived, used, and adopted by people. By placing humans at the center of our design focus rather than technology, our concerns shift in interesting and, hopefully, illuminating ways. For example, there are many ways to design and build a user-facing application, how do we know which path is the right one? What methods and guidelines can we apply to maximize our chances that our design is the most useful, usable, and enjoyable? In this class, you will learn to ideate, critique, prototype, evaluate, design and refine interactions, interfaces and applications for people.

CMSC838 - Tangible Interactive Computing

Course Description
In this course, we will explore the materiality of interactive computing. In the words of Hiroshii Ishii, we will seek to "seamlessly couple the dual worlds of bits and atoms." This is a particularly interesting time to survey and explore the space between atoms and bits because of three, interrelated technology trends:
  • The recent emergence (or reemergence) of the DIY/Makers movement, which has led to widespread opportunities to interface and work with hardware that has rather low barriers of entry (e.g., the Arduino) and provide new opportunities for tangible interaction;
  • The pervasiveness of powerful mobile computers in the form of smartphones and tablets that are constantly on and nearly constantly with us and imbued with a rich array of sensors such as accelerometers, gyroscopes, and location-sensing that allow for new types of off-the-desktop interaction;
  • The "hardware renaissance" in Silicon Valley (and other places) that is fostering a renewed culture of hardware-oriented products and ideas such as the FitBit,, the Lytro, the Pebble Smartwatch, Nest, Microsoft's Kinect, the Nike Fuelband, and low cost flying drones such as the AR.Drone.

Prospective Students
I am looking for undergraduate and graduate students passionate about investigating the role of technology in solving high-value social problems. If this interests you, please contact me so that we can setup a time to chat about mutual interests and potential research projects.
