As a microscopist and cell biologist I am interested in the use of microscopical techniques to visualize and characterize small biological structures. My main focus is the study of morphological features in symbiotic relations between plants and microbes. In addition I am interested in using quantitative microscopy, digital image processes and image analysis techniques to quantify morphological features. The application of microscope techniques resulted in collaborations with students and faculty involving various topics, including Morphological Study of the Trap Mechanism in the Carnivorous Plant Utricularia; Ultrastructural Analysis of the Coelomic Oocyte of Xenopus laevis; and the Three Dimensional Characterization and Visualization of Biofilms.
