Research Interests: I am a Ph.D. student here at UW-Madison. As of May 2007 I am a member of the Paradyn Project. I am currently working on adapting Dyninst to make it more robust on malware binaries that take defensive measures. Prior to joining Paradyn, my emphasis in database research and data mining. I looked into developing a database "Optimizer Medic" that is activated whenever a query estimate is significantly off the actual runtime of the query. This would result in the gathering of new statistics or in the updating of stale histograms and other datastructures. It seems to me that the best classifiers are often the least comprehensible. A classifier could be made easier to interpret by developing hybrid learning strategies that would divide the feature space into regions and apply simple classification models wherever possible, while not sacrificing the overall quality of the classifier and avoiding incomprehensible ensemble classifiers except on the most difficult regions of the feature space. The complexity of such a classifier is daunting, making it work at scale would be very important. About Me and my Family: I am very happily married and the father of two children, Monica Alicia and Jessica Alejandra. The requisite family webpage full of images and videos of my daughters is here. My wife Diana is from Colombia and my parents are also living in Colombia as missionaries for our Church. I have near-native Spanish speaking ability and am semi-fluent in Italian. |
