Research Interests

Functional Neurogenomics: We are interested in understanding how the genome constructs the brain, in both health and disease. One research direction is the development of technologies for genome-scale acquisition of expression patterns in the brain. These methods, voxelation and gene expression tomography, survey both the transcriptome and proteome and combine the mathematical concepts of biomedical imaging with the high-throughput analytic tools of genomics. Another research interest is the use of genetic mapping to identify loci influencing behavior in the mouse. We are also developing new methods to improve the power and utility of genomics in general. One approach employs the concepts of error-correcting codes to improve microarray performance and another uses hyperspectral imaging to speed hybridization assays. The ultimate goal of our research is to decode the conceptual wiring diagram of the genome which gives rise to the neuronal wiring diagram of the brain.
