Rate My Professor Steve Holland

Stephen (Steve) Holland is a Professor of Aerospace Engineering at Iowa State University of Science and Technology and Engineering Associate at the Center for Nondestructive Evaluation (CNDE). He earned his PhD in Theoretical and Applied Mechanics from Cornell University in 2002 and his BS in Electrical Engineering from Cornell University in 1997. Holland joined CNDE at Iowa State in 2002 and the faculty in 2006, where he leads the Thermography Research Group. His research centers on nondestructive evaluation (NDE) techniques, including vibrothermographic and pulse thermography for detecting flaws such as cracks in metals and delaminations in composites, spacecraft leak location using structure-borne noise, spatial NDE data registration and integration with CAD models, and NDE modeling with model-based inversion. Key areas encompass thermography analysis and modeling, ultrasound, vibrothermography physics, hybrid time- and frequency-domain modeling, Kalman filters, Markov Chain Monte Carlo estimation, and adaptive probability of detection methods. He developed the open-source SpatialNDE2 package for NDE data mapping and common data formats.

Holland's notable publications include "Model-based inversion for pulse thermography" in Experimental Mechanics (2019), "An Integrated Framework for Solid Modeling and Structural Analysis of Layered Composites with Defects" in Computer Aided Design (2019), "Quantifying the Vibrothermographic Effect" in NDT&E International (2011), "Thermographic signal reconstruction for vibrothermography" in Infrared Physics & Technology (2011), "Locating air leaks in manned spacecraft using structure-borne noise" in the Journal of the Acoustical Society of America (2007), and "Measurement of crack opening stresses and crack closure stress profiles from heat generation in vibrating cracks" in Applied Physics Letters (2008). His scholarly work has garnered over 1,800 citations. Holland is a Fellow of the American Society for Nondestructive Testing (2021) and has obtained funding from NSF, NASA, AFRL, Navy, and various SBIR/STTR programs with small businesses.
