CURRENT RESEARCH

 

My current research focuses on development of ecologically sound and economically viable biological control of Cercospora beticola, the causal agent of Cercospora leaf spot of sugar beet. The program concentrates on: 1) Search, screening and identification of potential agents for control of Cercospora beticola. 2) Influence of interaction between Cercospora beticola and its natural antagonists on biological control efficacy. 3.) Role of Cercospora toxins, namely cercosporin and beticolin in defense against natural enemies. 4) Development of a rapid protocol for detection of Cercospora beticola in plant tissues and application of the technique to screen for secondary hosts of C. beticola in the field.

RESEARCH EXPERIENCE

 

Prior to joining USDA as a Research Plant Pathologist in 2000, I worked as a postdoctoral fellow after my PhD in Ulrich Melcher’s Lab at the Department of Biochemistry and Molecular Biology, Oklahoma State University (OSU), OK from 1989‑1994. I then joined Vitaly Citovsky’s Lab at the Department of Biochemistry and Cell Biology, State University of New York (SUNY), Stony Brook, NY as Research Scientist.  At both OSU and SUNY, Stony Brook, my research focused on molecular biology and characterization of the plant virus Turnip vein-clearing virus (TVCV); I was also a key player in the prior discovery of TVCV at OSU. The research included determination of the complete nucleotide sequence of the TVCV genome and application of the genomic information to study virus host interaction. The sequence information led to the creation of a third tobamoviral sub-group. The sequence also provided basic information to various laboratories for subsequent and ongoing research on host-viral pathogen interactions with TVCV infection of Arabidopsis as a model systems. We also used the model system for studies such as cell-to-cell movement of plant viral infection and intercellular communications. After the work at OSU and SUNY, Stony Brook, I spent brief periods as a Minority Research Fellow at the Department of Biology, SUNY at Albany with Dmitry A. Belostotsky and a Research Associate in the Department of Plant Sciences, University of Arizona with Judy Brown.
