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 crucial factor that controls both the microbial community composition and their functionality within a given environment. This includes environments where microorganisms play significant roles in global carbon (C) and nitrogen (N) cycling.
Even in living cells, metals occur in trace amounts, but they have significant impacts on cellular metabolism, growth, and activity. Understanding how single cells in the environment regulate their metal uptake and how metal availability affects their activity are essential questions in comprehending how metals shape mixed microbial communities.
The primary goal of my Ph.D. project is to investigate microbial processes at the single-cell level, particularly in relation to trace metal availability, across a diverse range of environments. These environments span from freshwater to seawater and from anoxic to oxic habitats.
