Raghu S. Sangwan holds a Ph.D. in computer and information sciences from Temple University. He joined Penn State in 2003 after more than seven years in industry, where he worked mostly with large software-intensive systems in the domains of healthcare, automation, transportation, and mining. His overarching interest is in the analysis, design, and development of software intensive systems, their architecture, and automatic and semi-automatic approaches to assessment of their design and code complexity.

His work explores ways to effectively track, manage, and mitigate complexity, assessing the impact changes have on the overall quality of systems and their development flow. His work in agile and lean development approaches focuses on balancing providing early value with reducing rework and restructuring.

He actively consults for Siemens Corporate Research in Princeton and holds a visiting scientist appointment at the Software Engineering Institute at Carnegie Mellon University in Pittsburgh. He is a senior member of the IEEE and ACM.
