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. |
