Research Interests: MResearch in our group is focused on the development of integrated models of apical cell growth and morphogenesis, using the pollen tube as a biological model, ion dynamics as an experimental paradigm and theoretical modeling as an integrative tool. Pollen is the male gametophyte of plants, and therefore all the biological mechanisms we unravel can be integrated in terms of function and evolution and adds to our understanding of Plant Reproduction. We use Arabidopsis, lily, tobacco and tomato as model species for higher plants, and the moss Physcomitrella as an evolutionary correlate of apical growth evolution. To characterize ion choreographies we use a combination of methods, including imaging, electrophysiology, and molecular genetics.

We use transgenic and molecular tools to label and manipulate specific neuronal subsets in the visual system, electrophysiological and optical recording techniques to assay circuit function and connectivity, and high-resolution imaging techniques, including three-dimensional super-resolution fluorescence microscopy, to explore the molecular and structural refinement of developing circuits. By applying high-performance computing approaches to automated image analysis, we are working to extract new biological findings from big data.
