Main research Interest:
Metals are often found in trace amounts in aquatic environments where they play a key role in all major biogeochemical cycles. The availability of metals to microorganisms is a key factor controlling the microbial community composition and their functionality in a given environment, including those that play a significant role in global carbon (C) and nitrogen (N) cycling. In living cells, metals also occur in trace amounts, yet they play significant roles in the cellular metabolism, controlling growth and activity. How single cells in the environment control their metal uptake and what the effect of metal availability is on their activity are essential questions for understanding the role of metals in shaping mixed microbial communities.
The overarching aim of my Ph.D. project is to study microbial processes at the single cell level in relation to trace metal availability across a diversity of environments, from freshwater to seawater and from anoxic to oxic habitats.
