STRmix™ is expert forensic software, developed by ESR and Forensic Science South Australia (FSSA), that can resolve previously unresolvable mixed DNA profiles.

It has also been used successfully in numerous U.S. court cases, including at least 37 successful admissibility hearings. Internationally, STRmix™ has been used to interpret DNA evidence in more than 100,000 cases since 2012.
