I joined the Hawkesbury Institute for the Environment as a research fellow in the Soil Biology and Genomics theme in May 2016 and am working with Prof. Elise Pendall on biosphere-atmosphere exchange of carbon dioxide, water and methane. I am broadly interested in understanding the underlying processes that determine ecosystem properties and functioning, but also in assessing how ecosystems are affected by disturbances, management practices and changes in our climate. My previous research focussed on the fluxes of greenhouse gases and water across a range of ecosystems - from highly manipulated urban grasslands in Denver, Colorado to complex natural temperate forests in Victoria, south-eastern Australia.
Areas of research/teaching expertise
I gained my first research experience at the Water and Resources Division at the United States Geological Survey (USGS) and obtained my Master's degree at the University of Bonn, Germany. I moved to Australia for my PhD research at the University of Melbourne under the supervision of Prof. Stefan Arndt, Dr. Lauren Bennett and A/Prof. Patrick Lane. In the past four years my research focussed on seasonal growth dynamics of a mixed-species eucalypt forest, and I utilized an eddy covariance flux tower to examine ecosystem carbon sequestration dynamics and monitored stem and canopy growth dynamics to assess carbon allocation to the above ground biomass pools. Meanwhile, I explored the advantages of a novel terrestrial lidar for continuous monitoring of canopy dynamics as well as the effects of heterogeneous flux characteristics on estimates of seasonal and annual carbon exchange. In 2014 I obtained the Specialist Certificate in Teaching for Graduate Researchers at the University of Melbourne, Australia.
