Deepak Nanjappa
Yanfei Wang
Deepak Nanjappa, Ph. D.

Deepak is a postdoctoral researcher, investigating the transformability of raphidophyte species, Heterosigma akashiwo.  He recently began work in our algicide group project as well, where he is developing defined media for growth of algicidal bacteria in large bioreactors for increased production of the algicide.

Yanfei Wang, Ph. D. student

Yanfei received her masters degree in Marine Biosciences from UD-CEOE in 2016 and is now a PhD student in the program. She is investigating the application of matrix-associated algicidal bacteria to prevent harmful algal blooms.  This could be an environmentally friendly means to prevent blooms in areas at risk for algal blooms such as shellfish harvesting areas.

Daniel (Tye) Pettay, Ph.D.

Tye is a post-doctoral researcher working with Dr. Bill Ullman and Coyne at UD-CEOE. In Coyne's lab, Tye is directing the Heterosigma diversity research, investigating the genetic diversity of Heterosigma akashiwo in the mid-Atlantic region.

Yuechen Shi, MS student

Yuechen is studying the genetics, physiology and morphology of Heterosigma akashiwo.  Her work focuses on strains isolated from blooms in the Delaware Inland Bays and will be compared to strains from other parts of the world.

Christopher Grasso, MS student

Chris is researching the effects of a bacterial algicide on microbial populations in Delaware's inland bays. As part of this investigation, Chris will evaluate the effects of the algicide on microzooplankton grazing activities in small scale mesocosm experiments.
