Karupppasamy Subburaj is an Associate Professor in the Department of Mechanical and Production Engineering (MPE) at Aarhus University, where he has worked since 2023. His research asks how patient variability in anatomy, bone quality, and loading should change the design, manufacture, and validation of medical devices and interventions.

He has completed his PhD at IIT Bombay with Tata Memorial Hospital, developing 3D geometric reasoning methods for tumor-knee reconstruction and surgical planning. As a postdoctoral scholar at the University of California, San Francisco (2010–2014), he used quantitative MRI to study how knee and hip cartilage and meniscus respond to loading. At the Singapore University of Technology and Design (2014–2022), he was a founding faculty member in Engineering Product Development, led the Healthcare Engineering and Design track, and held an adjunct appointment at Changi General Hospital's Center for Innovation. He has supervised seven PhD candidates and more than 30 master's students.

He also holds a Master of Technology Entrepreneurship and Innovation (Sobey School of Business, Saint Mary's University, Canada) and an Executive MBA in Strategic Leadership.

He publishes as Karupppasamy Subburaj (K. Subburaj). ORCID 0000-0003-0723-2405.
