Nachiappan Nagappan works in the Empirical Software Engineering and Measurement Research Group (ESM) at Microsoft Research. His research interests are in the field of software measurement focusing on software metrics, software reliability, failure analysis/prediction and empirical software engineering processes. Prior to his current position he earned his PhD from North Carolina State University in 2005.
My work primarily focuses on large-scale commercial Microsoft systems. Currently my research interest focuses on the application of software measurement and statistical modeling to software systems. My work is primarily targeted at making early estimates of software quality to predict post-release failures. I also work on measuring test effectiveness, defect analysis and performing empirical case studies at Microsoft. Of late I have also begun working on social network analysis of developer contributions. If you have any questions please feel free to send me email.
