Brief Biography

Dr. Clar received a bachelor degree in chemistry from the University of Richmond in 2006.  After serving with AmeriCorps, he attended the University of Florida, earning his MS in 2010, studying arsenic mobilization during Aquifer Storage and Recovery Operations. Excited by the growth of nanoscience and nanotechnology, he remained at UF earning his PhD in 2014 studying the environmental implications of carbon nanotube separation and processing. During his graduate study Dr. Clar worked as an NSF GK-12 fellow developing environmental education modules for use in middle school classrooms.  After leaving UF, he worked as an ORISE Postdoctoral Participant at the EPA in the Land Remediation and Pollution Control Division (Cincinnati OH) studying the release of nanoparticles from outdoor surface coatings. Dr. Clar is now an Assistant Professor of Chemistry at Elon University where his research is focused on both the environmental implications and beneficial uses of nanotechnology.
