1) DNA Analyses of Forensic Materials

　DNA polymorphisms have been applied to personal identification and sex crimes. DNA technologies are often useful in analyzing decomposed samples. We study various SNPs (single nucleoside polymorphisms) and mitochondrial DNA typing.

2) Personal Identifiers using DNA Information

As a personal identifier, DNA information provides one of the most reliable markers. We have synthesized DNA containing base sequences that allow for personal identification yet protecting privacy. To use SNP systems as DNA-ID, we analyze the probability that two or more randomly selected people have the same type using population data of SNP systems.

３) Studies on Sudden Infant Death Syndrome (SIDS)

Rebreathing is an attractive hypothesis to explain the relationship between SIDS and a prone sleeping position. We are assessing some bedding on the assumption of the effects of rebreathing using a model; and the relationship between bedding and the potential for CO2 trapping has been analyzed using a mathematical formula.

４) Spectrophotometric analysis of the colors of bruises in living persons

Visual color impressions are subjective and as such cannot be completely relied on. The purpose of this study is to numerically analyze skin bruises on the living using spectrophotometric methods.

５） Practical Forensic Activities

We perform 270-280 autopsy cases every year.
