Medicine, in the very near future, will be able to provide patients with optimized treatments, such as individualized dosage of drugs and therapies. Patient variability with respect to such treatment response arises from variation in both the patients' genomic DNA as well as from environmental interactions. Our research will be directed towards combining genetic factors obtained from genomic sequence variation analysis/detection with gene-expression profiles obtained from microarray experiments; the final goal being their application to diagnoses and genetic therapies. Modern medicine must strive to avoid side effects stemming from the application of inadequate therapies. Towards this goal, one of the most important contributions we could make is genome-wide association studies for identification of disease and/or drug response related genes/variation. Using next-generation sequencer data, we will/have exhaustively explore variation of individuals' genomes and alterations in cancer genomes to a high quality. We will also develop theoretical frameworks and algorithms, and their practical extensions, for handling the ever increasing genetic variation, clinical and gene expression data, investigating disease-causing genes, and clarifying disease etiology.
