I am a research engineer with IIHR—Hydroscience & Engineering and the Iowa Flood Center, as well as the William D. Ashton Professor of Civil Engineering. I earned a degree from the U.S. Military Academy at West Point and further developed practical engineering skills during my service in the military.
Here at the University of Iowa, I lead a team that uses laser radar, or LiDAR, to measure atmospheric emissions near large livestock confinement facilities. LiDAR tracks the particulates, which act as tracers for the other components such as ammonia. It’s like watching smoke — you can see where it’s coming out and where it’s going.
My team uses LiDAR to record vertical slices in the atmosphere about three seconds apart. With that data, we can make movies of what’s happening, mapping the particulates’ movements in three dimensions.
