DESCRIPTION:Professor Sukhwan Yoon\, Korea Advanced Institute of Science &
  Technology (KAIST)\nAbstract:\nSince the first reports of the genomic and
  physiological evidence of the novel nosZ clade\, now termed nosZ clade II
 \, microbial reduction of nitrous oxide (N2O) has attracted many in search
  of environmental technology for mitigation of emission of this potent gre
 enhouse gas. Beginning with the breakthrough\ndiscovery revealing that cer
 tain subgroups of clade II nosZ-possessing organisms have a distinguished 
 ability to consume submicromolar N2O for utilization as the electron accep
 tor\, we\, the past and present members of Environmental Microbiology Labo
 ratory at KAIST\, have made substantial contributions in\nadvancing the ph
 ysiological and genomic understanding of N2O reduction\, especially pertai
 ning to biological nitrogen removal (BNR) processes in the wastewater sect
 or and nitrogen management of agricultural soils. We have verified\, via t
 wo disparate avenues of approach\, that the clade II nosZ\ndominate both g
 ene and transcript pools of nosZ in activated sludge microbiomes. In a sub
 sequent study combining culture-based experiments with computational analy
 ses of metagenomes and metatranscriptomes\, we have verified that nanomola
 r N2O consumption can occur in a sustainable\nmanner in microoxic environm
 ents and also that the key players belong to the close relatives of the ge
 nera Dechloromonas and Azospira\, the organisms presumed to be high-affini
 ty N2O-reducing organisms. Additionally\, we have applied these new scient
 ific insights in developing a self-sustaining N2O\nbiofiltration system\, 
 which can be implemented as a practical addendum to any BNR systems with m
 inimal alterations to the plant designs. The presentation will provide a b
 rief summary of these scientific and technological progresses we have cont
 ributed to the field over the past decade\, as well as an introduction of 
 the overarching research direction and long-term plans and objectives of o
 ur laboratory.\n\nShort biography:\nProf. Sukhwan Yoon is an Associate Pro
 fessor in Civil and Environmental Engineering at KAIST (Korea Advanced Ins
 titute of Science and Technology. He\nacquired his B.S. degree in Civil\, 
 Urban\, and Geosystems Engineering from Seoul National University Technolo
 gy\, and M.S. and Ph.D. degrees from the University of Michigan (2008 and 
 2010\, respectively). Before joining KAIST as an assistant professor in 20
 14\, he was a postdoctoral research associate at Max Planck Institute for 
 Terrestrial Microbiology (2010-11) and at University of Tennessee (2011-14
 ). He currently leads the Environmental Microbiology Laboratory (EML). The
  research group focuses on understanding and harnessing microbial reaction
 s to seek solutions to various environmental and sustainability problems\,
  which include\, but is not limited to environmental greenhouse gas emissi
 ons. He is currently serving as an associate editor for the Frontiers in M
 icrobiology journal and is a member of Y-KAST (Young Korean Academy of Sci
 ence and Technology)\, an honorable society of ~200 young Korean scientist
 s across all disciplines of science and technology
