Karthik Pattaje

Experience

Karthik Pattaje has conducted condition assessments of civil infrastructure, performed the repair design of concrete structures, researched the development of and evaluated concrete materials, and performed nondestructive evaluations.

Before joining WJE, Dr. Pattaje conducted research at the University of Illinois, focusing on fresh properties and mixture design of concrete. In his graduate research, he studied the effect of vibration on the rheology of concrete for 3D printing applications.
