The overall theme in my research is to understand the physiology of microorganisms living in deep-sea hydrothermal vent systems by the use of culturing, molecular biology, biochemistry and geochemistry.

Specific questions that I address are:

What is the diversity of energy metabolisms of hydrothermal vent microorganisms?

How do they link the cycling of carbon, nitrogen and sulfur in the system?

Do they have enzymes useful in biotechnology?
