Current work :
AquaDiva project A02 - Tracing Metabolic and Organic Signals through the Earth's Critical Zone (CZ). We are exploiting the versatility of metabolomics by developing profiling methods to detect, identified, and quantify the chemical diversity in the CZ. Comparing the metabolic activities in CZs under different surface conditions, microbial communities, and local geology will allow us to establish chemical markers to elucidate biogeochemical processes, identify the key players responsible for characteristic metabolic transformations, understand their benefits, and get insight into how growing human activities impact this zone.

Dr. Thomas Wichard

Wissenschaftlicher Mitarbeiter

Studies:

Diploma in Biochemistry from the University of Regensburg, Germany  (1995-2001).

PhD in Biochemistry, Max Planck Institute for Chemical Ecology in Jena, Germany (2002-2006).

PostDoc at Princeton Environmental Institute, Princeton University, USA (2006-2008).

Current work:

I am interested in understanding the factors controlling the interaction between macroalgae and bacteria in marine environments. Little is understood about how signal molecules mediate the symbiosis across the kingdom and support the morphogenesis of macroalgae. My research involves trying to identify algal and bacterial compounds, which shape the symbiosis of the green algae Ulva sp. and its bacteria. Using combined approaches of analytical chemistry and molecular biology I aim to decipher the signal molecule based cross-talk in laboratory cultures before field experiments will be conducted.

Current Work:

I'm investigating volatile organic sulfur species (S-VOCs) that are emitted by soil microbiota in the Hainich and the Amazon region. We want to understand how factors like soil moisture or temperature change S-VOC emissions in nature and which organisms are mainly responsible for which substance at the different environmental conditions applied.

Interests :

- total synthesis of natural products and generation of derivatives

Current work :

The aim of my thesis is to investigate the induced defence of microalgae by elicitors. Therefore, the total synthesis of Copepodamides is to be established, in order to verify the proposed structure. Producing derivatives of the natural product will also shed light on the structure-activity-relationship (SAR) of these first known inducers of defence in microalgae.

Interests:

Environmental and ecological chemistry, particular interest in how micro-organisms interact thanks to chemical signals and application of these knowledge to technological problems.

Current work:

Diatoms are the most important primary producers in the oceans. They are known to have an asexual reproduction cycle that turns to a sexual one when they reach a treshold size. Recently, the first pheromone involved in the sexual reproduction of a diatom (Seminavis robusta) has been discovered. In my work, I will try to understand how bacteria associated to S. robusta can interact with this pheromones and affect the reproduction cycle of this diatom.
