Alex Craig

Assistant Professor

Director, BLST

Prof. Alex Craig has been an active researcher the field of boundary-layer stability and transition and hydrodynamic stability for 11 years with experience in both incompressible and compressible flows. His research has primarily focused on the experimental study of high-speed and hypersonic boundary layers. Prof. Craig recently conducted a study on the nonlinear interaction between waves in a hypersonic boundary layer in a quiet wind tunnel, which provided evidence of a possible triad interaction. He also performed the first-ever detailed mapping of a crossflow-dominated hypersonic boundary layer, revealing a substantial similarity between hypersonic and subsonic crossflow vortices. Additionally, he has conducted experiments using dielectric barrier discharge (DBD) plasma actuators as a flow control device for implementing transition delay on low-speed swept wings in wind tunnel and flight tests. Recently, his team has completed the reactivation and shakedown of a Mach 4 quiet Ludwieg tube. A Mach 5 Ludwieg tube has also been constructed by his team and was recently declared fully operational.

Prof. Craig is an active member of the American Institute for Aeronautics and Astronautics (AIAA) and a member of the AIAA Fluid Dynamics Technical Committee. He is also a member of the National Defense Industrial Association (NDIA). He has given a number of invited lectures around the U.S.
