Staff Scientists
Barbel Kohm
Dr. Kohm is a German-American plant virologist.  Her research
has focused on the detection of the common potato viruses and
their interaction with natural and engineered resistance genes,
e.g. the development of alternative serological diagnostic tests
for PVX, PVY and leaf roll virus;  mapping the interactions
between various PVX strains and the potato's resistance (R)
genes;  and the field characterization of engineered PVY
resistance genes.  Current research interests
concentrate on
PCR-based methods of pathogen detection.

James Spychalla
Dr. Spychalla is a third generation Wisconsin potato grower.  His research has
focused on the biochemistry and molecular genetics of hexose and fatty acid
metabolism in the postharvest potato,
e.g. natural and engineered gene resistance
to both low-temperature sweetening, and physiological aging.  Current research
concentrate on improving common scab resistance.
