  • Postdoctoral Research Associate , University of Southern California and Center for Dark Energy Biosphere Investigations (since 2012)

My current effort focuses towards the use of calorimetry in combination with continuous culture methods (i.e. chemostats) to accurately measure the heat generated from microbial metabolic activity. My specific aim is to use nanocalorimetry for the characterization of  microbial energy metabolism in low-­‐ energy environments.

My main responsibility is the development of culture-­‐based approaches for the
discovery and monitoring of microbial reactions.


  • Postdoctoral Research Associate , NASA Astrobiology Institute and University of Hawaii (2009-2012)

I studied temperature and pressure as important environmental physical factors regulating the diversity and specific energy metabolism of microbial populations involved in the biogeochemical processes in deep subseafloor environmens. The main focus of my research was on he ecophysiological constrains resulting from temperatures at the upper and lower limits for growth.

My specific responsibilities were the fabrication of a pressure/temperature gradient system and the implementation of sensitive laboratory tracer and molecular techniques.
