As a biochemist and ecophysiologist by training, I have acquired expertise in the effects of various environmental factors (particularly light and water) on plant growth and nutrition. Previous work on the remobilization of carbon and nitrogen molecules led me to study fertilizer inputs in relation to substrate properties and application methods.
