Bio
My work lies at the intersection of data mining, machine learning, and information retrieval, including work on relevance and CTR prediction for online advertising, information filtering (such as email spam and blog comment spam filtering), text analysis, digital libraries, and online advertising systems. I have also done work in computational biology and the digital humanities, and have a particular interest in scalable methods. I have been employed in Google's Pittsburgh-based office since 2008, working on problems in online advertising and user experience. My daily work involves a mix of research, engineering, technical team leadership, and management.
