Research and Work

• Facebook Software Engineering Intern, Summer 2012 - We worked on an automated system to detect and respond to ill-gotten page Likes (related to Facebook Security's post on the subject).
• Data Mining with Professor Christos Faloutsos - Studying epidemic models for multiple viruses.
• Computational Geometry with Professor Pankaj Agarwal and Thomas Mølhave - Working on optimizing approximate natural neighbor interpolation both for speed and complexity.
• CS Systems Research with Professor Xiaowei Yang - We worked to leverage the TPM to verify online actions. (paper pending)
• Duke High Energy Physics Lab - Neutrino Group - I optimized ROOT for large data transfers with the networked servers at our lab facility in Japan, Super Kamiokande. I also worked with Geant4 and ROOT to create a system for monte carlo testing, reviewing, and analyzing possible new water cerenkov detectors for future neutrino experiments.
