The mission of the Susquehanna River Initiative is tri-fold: develop teaching, research, and outreach experiences that connect faculty and students to the river.

I also work closely with the Environmental Center’s other two initiatives - the Campus Greening and Sustainability initiative and the Natural and Human Communities initiative. Since starting in 1996, we’ve experienced tremendous growth in research, student and faculty involvement, and other activities as we partner with other universities and agencies in the watershed.

Much of my professional life has been devoted to environmental restoration and habitat improvement projects in the Pacific Northwest, New England, and mid-Atlantic regions of the United States. I'm currently working on projects related to:
  • impact of historic logging on rivers
  • wetlands hydrology and restoration
  • impacts of land use and climate change on the Susquehanna River
  • bedload transport and pool/riffle formation in nearby streams
  • improving trout habitat in gravel bed streams

I spend a lot of time wading or floating the Susquehanna River and its tributaries, measuring the flow of water and sediment in the streams, the shape of the channel and surrounding flood plains, and try to relate these things to the land use, geology, climate, and hydrology of the watershed. I also develop and maintain the hydrologic monitoring network at
Montandon Marsh and enjoy leading trips to this beautiful wetland. Most recently, I’ve been helping the sand and gravel mine owners come up with ways to better reclaim their extraction site so as to minimize the impact of their operations and leave behind a more natural wetland and not an abandoned pit.

Several times a semester, I put together kayak trips on the Susquehanna to engage faculty and students on the hydrology and ecology of the river. There’s no better way to discuss the environmental issues facing this watershed than to spend time on the water. I also provide guest lectures on stream restoration and aquatic habitat improvement to watershed groups and undergraduate classes.

Every semester I try to offer some kind of environmental stewardship or Susquehanna appreciation activity for the public, including river float trips, wetland tours, mountain hikes, or star-gazing fun.

A little here ... a little there ... I'm still try to make sense of this world, one watershed at a time.
