Intereses de investigación

a) Flujos de carbono a través de tramas tróficas pelágicas.

b) Flujos de elementos y partículas a zonas profundas del océano.

c) Acoplamiento entre zonas pelágica y bentónica.

d) Ecología de microorganismos.

e) Análisis/modelación ecotrófica  a nivel de ecosistemas de la Patagonia.

El laboratorio de Oceanografía Biológica ha llevado a cabo investigación científica en la última década en sistemas de fiordos y canales de la Patagonia Chilena. El énfasis ha sido estudiar los flujos de carbono a través de tramas tróficas clásica y microbiana. Hemos realizado modelos conceptuales y de flujos tróficos para diversos sistemas Patagónicos. El laboratorio ha relizado extensos estudios sobre la taxonomía y ecología de diversos grupos del plancton como bacterioplancton, fitoplancton (diatomeas, cocolitofóridos), microzooplancton (tintínidos, dinoflagelados tecados y desnudos) y mesozooplancton (copépodos, krill)
