Profile

Dr. Gotoh graduated from the Department of Physics, Faculty of Science, University of Tokyo and received Dr. Sci. in biophysics from that institution in 1978. He worked as a research scientist in Saitama Cancer Center Research Institute and National Institute of Advanced Industrial Science and Technology before he came to Kyoto. His present major research field is bioinformatics, particularly genome informatics. He is currently involved in development of algorithms and software for analysis of massive genomic sequence data and also interested in application of the methods to uncover important biological signals cryptically encoded in the genome sequences. His group has developed several computer programs that are publicly distributed. The most recent ones are 鉄paln and 鼎galn. The former maps and aligns a large number of transcripts onto a genome very accurately, while the latter can efficiently compare mammalian sized huge genomic sequences on a nominal computer. He is a committee member of classification and nomenclature of cytochrome P450 gene superfamily, which collectively encodes a major class of drug-metabolizing enzymes in both prokaryotes and eukaryotes. He was the president of the Japanese Society for Bioinformatics from 2008 to 2009.
