Research & Publications

Recent News

My research interest is in the area of garbage collection. My work is not exactly the same as those guys who drive a big garbage truck down your alley once or twice a week. On the contrary, it is related to object-oriented programming especially in the Java programming language and .NET computing framework. I am a member of The Laboratory for Empirically-based Software Quality Research and Development (ESQuaReD). More information about my research activities can be found below:

Hobbies

Since I work in a rapidly changing world of computers, I like other things around me to be a lot more static (almost like frozen in time). For example, I love automobiles from the late 60's and early 70's. This is especially true for my all time favorite marque, Alfa Romeo. Living in the US provides a great incentive for owning an Alfa. First, the car is not well loved by most, so the price is very reasonable. Parts are not terribly difficult to find. They are also easy to work on.

In addition, I love to cook. I like to take photographs using the old Contax SLRs from the 70s and listen to my favorite songs on my old but trusty 1972 Linn LP12 turntable.
