DESCRIPTION:Environmental Engineering Graduate Seminar\n\nGreg LeFevre\, De
 partment of Civil & Environmental Engineering | University of Iowa\n\nAbstr
 act: Plants are all around us and have been a strong synergy between ecolog
 y and environmental engineering for decades. Plants can interact with pollu
 tants both by helping to clean up environmental contaminants or may serve a
 s an exposure route to humans for contaminants that are present in the food
  supply. In this seminar\, I will present our research that probes mechanis
 tic understanding of plant uptake and transformation processes for emerging
  organic contaminants in green stormwater infrastructure as a remediation a
 pproach and recycled water for crop irrigation as a potential human exposur
 e route. Our group employs lab and field-based studies to understand what t
 ypes of emerging contaminants are likely to be taken up by plants\, passive
  vs. active uptake mechanisms\, the first discovery of plant excretion\, pr
 oduct to parent reversion of conjugated phytometabolites in the rhizosphere
 \, and in vitro digestion simulations to assess contaminant bioaccessibilit
 y within plant tissues. We use high-resolution mass spectrometry for metabo
 lomics and products/pathways discovery to determine what contaminants trans
 form within plants and following digestion\, and how plants respond to cont
 aminant exposure. We also employ computational chemistry modeling approache
 s to enhance apriori predictive power. Understanding how plants take up and
  transform contaminants will enable better contaminated site clean up as we
 ll as ensuring clean food and water supplies.\n\nBio: Greg is a proud Michi
 gan Tech Husky Alum (class of 2007) and loves connecting engineering princi
 ples to nature-based solutions to improve environmental quality. He is an a
 ssociate professor of environmental engineering and science in the Departme
 nt of Civil & Environmental Engineering and IIHR—Hydroscience & Engineering
  at the University of Iowa where he started in 2016. He did his BS at Michi
 gan Tech\, MS and PhD at the University of Minnesota\, and Postdoc at Stanf
 ord University all in environmental engineering. The LeFevreLab focuses on 
 elucidating biotransformation products and pathways of emerging organic con
 taminants with the goal of informing improved design of ‘engineered-natural
 ’ treatment systems for non-point pollutants\, like urban stormwater and ag
 ricultural drainage\, and transform wastes into resources. Greg has receive
 d multiple sources of recognition for his work\, including the National Sci
 ence Foundation CAREER Award\, the University of Iowa Early Career Scholar 
 of the Year award\, the American Chemical Society Editor’s Choice award and
  ACS Best Paper award\, ES&T James Morgan award (honorary mention)\, the Ro
 yal Society of Chemistry Environmental Sciences ‘Best Paper’\, National Aca
 demy of Engineering Frontiers of Engineering fellow\, the AEESP Best Disser
 tation (both as a PhD student and faculty advisor)\, amongst others.
