Research Interests

We are trying to elucidate the role of ubiquitination in neuronal development. Using a biochemical approach, we have developed a novel proteomic strategy that allows isolation of ubiquitinated material from the brain of a living organism. So far, we are using Drosophila for this purpose. We have also applied the same approach to isolate SUMO conjugates in a tissue specific manner.
