Visiting Scientists:

Sangkyu Park is in the Department of Life Sciences at Ajou University, Suwon, South Korea and did his sabatic leave in 2013  in the Hegeman lab studying the interactions between eurasian watermilfoil (Myriophyllum spicatum) and certain cyannobacteria, (Microcystis aeruginosa).

Dongwoo Yang is a postdoc with Sangkyu Park at the Department of Life Sciences at Ajou University, Suwon, South Korea.  He was performing LC-HRMS-metabolomics analyses of plant samples collected around the Arctic in June 2015 to examine the effects of the warming climate on phytochemistry.

Debby Filler is a professor in the Biology Department at Anoka-Ramsey Community College in Coon Rapids MN.  She was awarded an NSF Research Opportunities Award (ROA) supplement to our Metabolic Flux grant to characterize antimicrobial compounds in curlycup gumweed (Grindelia squarrosa) during her sabbatical leave.

Daqing Yang is based at the Hormel institute in Austen MN and is working with the Cleary lab.  He has visited our lab to run mouse serum samples or mammalian cell extracts to analyze relative pathway utilization via positional isotopic analysis.
