GIS and its associated technologies continue to be increasingly important in the environmental and engineering industries. I am continually amazed by the innovative use of these technologies and am always looking for ways to incorporate them into the work that we do.

Tell us about your most exciting or rewarding project at Straughan.

The stream daylighting work we did with the DC Office of Energy & Environment was a unique opportunity that allowed us to showcase, using GIS technologies and historic mapping, how DC’s development from its inception to the present has affected its hydrology and how streams that were once piped underground could be returned to the surface. GIS is not always tangible, so being able to use these technologies to tell a compelling story is something that I am particularly proud of.

What led you to this career?

I’ve always had an affinity for geography and maps. During my junior year of college, I took an Introduction to GIS course and was astounded that such a thing existed. It was then that the lightbulb went off in my head and I knew GIS needed to be part of my career.
