	Jon Hulvey Postdoctoral Researcher 107 French Hall 230 Stockbridge Road University of Massachusetts Amherst, MA 01003 Phone:(413) 577-3303 jhulvey@umass.edu My research in the Turf Pathology and Breeding Lab concerns the genetics and biology of Sclerotinia homoeocarpa, with a focus on molecular mechanisms of resistance to fungicides using functional genomics tools. I am also working to develop new genetics-based diagnostic tools for turfgrass pathogens.

	Sara Weil PhD Student I am a Plant Biology student doing a rotation in the Jung Lab. I am working with Loreto, developing PCR-based markers (conserved intron spanning primers; CISPs) for cool season turf grass species and other Pooideae species based on EST sequence comparison between Agrostis and Brachypodium.

	Emily Olesin Undergraduate Student For my Commonwealth College honors thesis project I am examining genetic differences between free-living and attached forms of the common marine brown alga Pylaiella littoralis(L.) Kjellman. While the Jung lab is foremost a turf pathology laboratory, it has the people and the equipment to foster other molecular projects like mine. Working in the Jung lab has been an eye-opening research experience that has helped prepare me for a career in molecular studies.
