We are focused on how cells adapt to changes in their environment. Several systems are under investigation including innate immunity in plants, pluripotency in stem cells, self-renewal in cancer cells (embryonal carcinoma and chronic lymphocytic leukemia), and environmental stress in microalgae. To facilitate these studies, we are developing and applying technology for peptide mass spectrometry to enable direct observations of protein dynamics and protein networks on a genome-wide scale. Much of our technology development is done in collaboration with Prof. Vineet Bafna and Prof. Pavel Pevzner in the department of Computer Science and Engineering at UCSD with whom we co-mentor students under the auspices of the IGERT Plant Systems Biology Training Grant and the Interdisciplinary Bioinformatics Program. Additional training opportunities are provided by the Center for Algorithmic and Systems Biology, by the San Diego Consortium for Systems Biology, and by the San Diego Center for Molecular Agriculture.
