I am a Principal Researcher and co-manager of the Research in Software Engineering (RiSE) group in Microsoft Research, Redmond Washington, a group of over 30 researchers and developers working on programming languages and software engineering.

Previously, I was an Associate Professor of Computer Science at the University of Colorado from 1990-1998. I have a BS from Rensselaer Polytechnic Institute (1982) and an MS (1984) and PhD (1989) from the University of California at Berkeley.

My research interests include programming language design and implementation and performance measurement and analysis.

I have served as an Associate Editor of the ACM journalsTransactions on Programming Languages and Systems and Transactions on Architecture and Code Optimization and I am currently a member of the ACM SIGPLAN Executive Committee. I have also served as the Program Chair (1999) and General Chair (2010) of PLDI and am currently serving as a member of the Computing Community Consortium (CCC) Council.  For further information about my research and professional activities, please see my vita.


Logan: Logfile Analysis

Established: October 12, 2015

Understanding Techniques and Tools for More Effective Telemetry and Log Data Analysis. Increasingly, business processes require data-driven real-time feedback based on large quantities of log data and customer telemetry from multiple sources. The Logan Project takes a broad approach to understanding the specific needs of consumers of telemetry and log data, focusing on giving them better support for extracting the data they need, cleaning it, and creating queries against it. To understand the needs of…

Project Premonition

Established: March 2, 2015

Interested in evaluating Project Premonition technologies and data? Sign up here Project Premonition aims to detect pathogens before they cause outbreaks Emerging infectious diseases such as Zika, Ebola, Chikungunya and MERS are dangerous and unpredictable. Public health organizations need data as early as possible to predict disease spread and plan responses. Yet early data is very difficult to obtain, because it must be proactively collected from potential disease sources in the environment. Researchers estimate between…

JSMeter: Measuring JavaScript Web Applications

Established: March 2, 2010

The goal of JSMeter is to measure the runtime behavior of JavaScript programs. Our ultimate goal is to improve the quality of JavaScript engine implementations. Can you tell the JavaScript benchmark from the Real Web App?   Abstract JavaScript is widely used in web-based applications and is increasing popular with developers. So-called ”browser wars” in recent years have focused on JavaScript performance, specifically claiming comparative results based on benchmark suites such as SunSpider and V8. In this…

Detection of JavaScript-based Malware

Established: December 8, 2008

Nozzle: Runtime heap spray detector Nozzle is a runtime monitoring infrastructure that detects attempts by attackers to spray the heap. Nozzle uses lightweight emulation techniques to detect the presence of objects that contain executable code. To reduce false positives, we developed a notion of global “heap health”. The Nozzle lightweight emulator scans heap allocated object data to identify valid x86 code sequences, disassembling the code and building a control flow graph. Because the attack jump target…

OS and tools for building dependable systems. The Singularity research codebase and design evolved to become the Midori advanced-development OS project. While never reaching commercial release, at one time Midori powered all of Microsoft's natural language search service for the West Coast and Asia. "...it is impossible to predict how a singularity will affect objects in its causal future." - NCSA Cyberia Glossary What's New? The Singularity Research Development Kit (RDK) 2.0 is available for…
