I hope to continue doing what I like best: attempting to maintain perspective on research in computer science and the industry, and from that perspective, selecting high-impact problems amenable to solutions requiring more thinking than typing. Not that I refuse to or don't code, but I view my talents more in code obviation by finding hidden cross-disciplinary connections that allow some topological or graph-theory identity to substitute a formula for a search.

I've worked on a wide variety of areas in computer science, and continue to look for systems problems where mathematical and theoretical techniques might be applied judiciously. Some previous successes have included: multiprocessor memory architectures, which led to work on competitive algorithms; window systems, which led to work on methodologies for concurrent programming, and to the studies behind low-bandwidth X; distributed computing, which afforded the opportunity to work on integer factorization; and, most recently, the Web, which has led to investigations into cryptographic protocols for exchanging very small quantities of money (the MilliCent project), and techniques and applications for discovering syntactic similarity among large collections of documents and applications for measuring the rate of evolution of web pages.
My most recent efforts have been focused on completing a long-standing but intermittent research agenda into similarity detection begun with Alta Vista, refreshed with Bing, and repurposed for network compression in the Windows Server distributed file system, the publication in 2012 of a textbook summarizing the above and advances designed to address deficiencies therein, and this year's work improving the performance by two orders of magnitude by employing techniques first found by Flajolet and Martin.
I have also been recently considering erasure coding techniques for extending the usable lifetime of emerging non-volatile memory technologies when used to replace DRAM. Additionally, I have been working on a data-mining project to detect urgency in the trail of browsing and search queries made by a user (often from a smart phone) to detect when an emergency medical situation might suggest a more streamlined and tailored search experience to quickly help a bystander learn how to perform basic CPR, say, while awaiting arrival of the emergency medical services whose summoning was assisted by the phone upon detection of the user's state of distress.
At Microsoft, I made investigations into applications of cryptography for spam reduction, into petabyte-scale reliable storage, into web evolution and the connection to web spam.
