// about A bit more about me
I build and use models to understand how water moves through real places, then I try to make
that work easier for other engineers to do.
At AECOM I lead the H&H Technical Excellence Practice, so a lot of my day is hydrologic and
hydraulic modeling, flood-risk reduction, dam-breach and floodplain studies, technical reviews,
and figuring out where AI actually helps in H&H work. Before AECOM, most of my research was on
cold-climate and depression-dominated landscapes, where snow, frozen ground, and shallow surface
storage change the rules. I built Macro-HyProS, a macro-scale hydrologic simulator for those
settings, and have written about snowmelt, frozen-ground recession, DEM resolution, and watershed
delineation. There is more on the projects and publications pages.
I taught water resources, hydrology, fluid mechanics, GIS, and senior design as a professor at the
University of St. Thomas and Bucknell, and as a teaching assistant at North Dakota State. I still
enjoy teaching, so I keep at it through a Python course, recorded lectures
on YouTube, and the open-source tools on my GitHub. Outside of work I take a lot
of photos (see the photography page), usually of water, and usually with
my dog Olive somewhere nearby.
