Research Interests
Carl is active in the Mahoning River Consortium as an advocate for river restoration and is active in remediation and restoration research. He collaborates with faculty and students across STEM at YSU and with industry partners conducting research on bioremediation of 1) contaminated river sediment and 2) water impacted by mine waste. Bioremediation is being considered by the United States Army Corps of Engineers for restoration of the Mahoning River. His collaboration with BioRemedial Technologies Inc. (BRT), and Winner Global LLC is focused on optimizing activity of indigenous sulfate reducing bacteria to treat acid mine drainage. Carl is working towards technology scale up and full-scale bioremediation.
