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.

As a research associate in the Jung lab, I conduct field efficacy testing of fungal control agents, conduct in vitro fungicide sensitivity assays for Sclerotinia homoeocarpa, advise golf course superintendents on management of fungicide resistant S. homoeocarpa populations, write scientific and extension articles, keep the lab stocked and oversee maintenance of plant collections and field plots

As a Master's student in the Turf Pathology and Breeding Lab, I conduct research on the effect of early spring and late fall applications in the development DMI fungicide resistance in Sclerotinia homoeocarpa. I am also the superintendent of the Whitehall Field Club in Whitehall, New York and work as a consultant for golf courses in New York.

Sarah

 

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.

 

 

 

Changho Ok
Postdoctoral Researcher

I studied fungicide resistance and field efficacy of dollar spot (Sclerotinia homoeocarpa) populations both in vitro and in field experiments on several golf course fairways throughout Massachusetts and Connecticut.

 

 

 

Leah Zivalic
Research Associate

I worked on identifying the molecular mechanism's responsible for fungicide resistance in Sclerotinia homoeocarpa.

 

 

 

Jeonghwa Lee
Postdoctoral Researcher

I researched functional genomic approaches for fungicide resistance.
In particular, I investigated the determinant factors controlling fungicide resistance in the fungal pathogen Sclerotinia homoeocarpa found on golf courses
