I am currently a Researcher at Microsoft Research working on Empirical Software Engineering as part of the Research in Software Engineering RiSE group. I received my bachelor’s degree in CS from Brigham Young University and my Ph.D. in Computer Science from UC Davis, studying empirical software engineering under my advisor Prem Devanbu.  I’m currently working on ways to use data to guide decisions of stakeholders in large software projects.

I currently work with Thomas Zimmermann and Nachi Nagappan in the Empirical Software Engineering (ESE) group at Microsoft Research.


Software Process

Established: February 7, 2012

Our studies on software process include organizational impact on quality, agile software development, global software development, effort estimation, development branches, and build analysis.

Software Reliability

Established: February 7, 2012

This project investigates how factors such as complexity metrics, churn, organizational structure, dependencies, and social networks relate to software defects and failures. This information is used to build prediction models that can help to prioritize tests.
