Educational Background
Ph.D., Agronomy, 2006,
Division of Plant Science, University of Missouri – Columbia,
Columbia, MO, USA.
B.S., Molecular Biology,
1999, Institute of Cell and Molecular Biology (ICMB), University of
Edinburgh, Edinburgh, Scotland.
Research Interests
My research interests are
focused on plant molecular biology and genetic manipulation of plants
to provide human and animal livestock with better sources of nutrients
and also explore and enhance plant genome using molecular techniques
and approaches.

Featured
on Cover - “Soybean proteins are under-represented
in sulfur containing amino acids. Improving the sulfur
amino acid content requires a detailed understanding of the sulfur
biosynthetic pathway. Manipulating the expression levels of O-acetylserine
(thiol) lyase, a key enzyme that catalyzes the formation of cysteine,
can lead to an increase in sulfur amino acid content of soybean seed
proteins”, Crop Sci 43: 1819-1827. Cover design by D.
Chronis.
