Dr. Steve Holland

Welcome to my home page!

I am a professor at Iowa State University in the Department of Aerospace Engineering. I specialize in thermographic methods for nondestructive testing of materials. I am a 2002 Ph.D. graduate of Theoretical and Applied Mechanics a 1997 B.S. graduate of Electrical Engineering, both at Cornell University. I am a native of Wayland, Massachusetts, a western suburb of Boston.

Projects

Since 2005 I have been building the thermography research program at the Center for Nondestructive Evaluation

• Vibrothermographic (Sonic IR) nondestructive testing (research group).
• Dataguzzler -- A laboratory data acquisition platform for high-performance waveform and image acquisition
• Air-coupled ultrasonic measurement
• Locating leaks in spacecraft
• AviaScene -- A virtual environment for remote exploration (Open source!)
• Aglaophone -- A system for real time analysis and manipulation of audio. (Open source!)
• VeryNice -- Automatic process renicer for UNIX/Linux (Open source!)
