symbioses among soil organisms fascinate me. I study arbuscular mycorrhizas,
which are fungal symbioses with most terrestrial plants. Mycorrhizas in natural
and agricultural systems are my primary research focus. A better understanding
of the factors controlling the balance of trade between plants and mycorrhizal
fungi could lead to their management so that fertilizer inputs can be reduced.
Also, since mycorrhizal fungi are enormous (yet invisible), understanding how
to manage them may help generate an important belowground carbon sink in our
increasingly carbon dioxide enriched world.
