		Andrea Bauer PhD Student Studies: Chemistry, FSU Jena (2003-2009) Interests: I am interested in analytical chemistry and microbiology, especially bacteria and their secondary metabolism. Current work: My research is focused on bacterial Quorum Sensing (communication between bacteria via signaling molecules). I investigate mechanism of this communication system, the structure of the signaling compounds and processes, which are controlled by QS. Another part of my work will be the possibility for direct controlling bacterial processes via QS. Also I want to investigate which genes are important for this regulation system.

		Carsten Paul PhD Student Studies: Since 2003: Study of Chemistry/Environmental Chemistry, Friedrich Schiller University, Jena Interests: I am interested in the interface between chemical ecology and analytics. Primarily the chemicaly mediated interactions between both marine and terrestrial organisms, for example the formation of algal blooms or tritrophic interactions. Current work: Within the annual cycle diatoms are able to form blooms. I am investigating the role of diatom derived secondary metabolites as semiochemicals in this dynamic process.

		Michaela Mauß PhD Student Studies: Biology/Ecology at the University of Vienna (2002-2008) Interests: My interest is mostly attracted by the dynamics of symbiotic or other types of interactions in the marine environment, especially if the participants belong to different domains or biological groups. Current work: Viruses are by far the most abundant entities within the marine environment and their crucial role in phytoplankton regulation is widely accepted. Nevertheless, their complex interaction with the host is only fairly understood. My work aims to detect (bio)chemical ways of interactions of the coccolithophore Emiliania huxleyi and its specific viruses via metabolomics. Further I will try to access metabolic differences in haploid and diploid life phase as well as virus resistant and non-resistant strains.

It is degraded to biliverdin by heme oxygenases and subsequently oxidized to bilirubin. Under conditions of oxidative stress further degradation of bilirubin can appear. The characteristics of the mono- and dipyrrolic end products are in the focus of my research.

		Johannes Frenkel PhD Student Studies: Biology/Microbiology (2006-2010) at the Friedrich-Schiller-University Jena Current work: Diatoms multiply via vegetative reproduction. After each cell division, the average cell size decreases due to the structure of the algal cell wall. Once they reach a critical cell size, they have to undergo a cycle of sexual reproduction to restore original cell size, otherwise the cells would die. Task of this PhD-Thesis is to find a pheromone used by the diatom Seminavis robusta which helps to attract possible mating partners. Interests: - Connection of Biology and Chemistry by investigating the metabolism of organism via metabolomic and proteomic approaches - modern methods of analytical chemistry

Master Thesis at the Chamlers University of Technology in Göteborg, Sweden 2008/2009. Interests: I am interested in the role secondary metabolites of siphoneous green algae play in wound reactions and in the analytical methods, mainly LC-MS, GC-MS and NMR, to investigate the metabolites.

		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.
