Process manuscripts on microalgal taxonomy for the European Journal of Phycology.

Current research focuses on gene regulation of unicellular-multicellular development and phenotypic plasticity

in Desmodesmus, a freshwater green alga (collaborate with colleagues; supervise PhD research projects;

sponsor student volunteers).

RESEARCH INTERESTS

My recent research has focussed on gene regulation in Desmodesmus, as a model to understand the origin of

multicellularity, predator-prey relationships between Daphnia and Desmodesmus, and taxonomy of

Desmodesmus using a polyphasic approach (molecular, culturing and SEM).

The focus of my research earlier in my career was the ecology and physiology of aquatic algae, terrestrial algae

and the use of algae as indicators of environmental change. Research topics that I have investigated include:

ecological studies of phytoplankton and periphyton (Devils Lake, Fox Lake, Kellys Slough, USA; Welsh coast,

Pembroke, Wales and Kindrogan, Scotland); terrestrial studies: soil algae (prairie, desert and forest ecosystems,

open cast mining and metal contaminated soils); and laboratory studies (heavy metal uptake, stress proteins,

phenotypic plasticity, development)

Photoorientation of Flagellate Green Algae
Our research is focused on the analysis of the eyespot apparatus, the „eye“, of flagellate green algae. Using a combination of biochemical, cell and molecular biological techniques we try to functional characterize this primordial visual system. A detailed description of the structure and function of this algal “eye” can be found in the following review (Kreimer 2009, Curr. Genet. 55, 19-43). Due to their elaborate structures and the presence of retinal-based photoreceptors in some lineages, algal eyespots are thought to play an important role in the evolution of photoreception. The eyespot apparatus of green algae utilizes specialized microbial-type rhodopsins as photoreceptors, which act as directly light-gated ion channels. After establishment of an isolation method for the eyespot apparatus in its entire complexity and its core- and phospho-proteome (Schmidt et al. 2006, Plant Cell 18: 1908-1930; Wagner et al. 2008, Plant Physiol. 146: 772-788), we are now interested in the signal transduction cascades leading to the photoresponses of these algae and the mechanisms underlying the tight interaction of the different subcellular compartments in this region of the cell. Our current focus lies on the functional characterisation of novel Ca2+-binding proteins and the analyses of protein-protein interactions and protein complexes. Another topic is focused on
the functional analyses of the blue light photoreceptor phototropin. For this we are employing different experimental approaches like e.g. RNAi, immunoprecipitation and different 2D-electrophoretic approaches in combination with mass spectrometry. Our main model organism is the green alga Chlamydomonas reinhardtii
