Achievements include contributed to the fundamental science as they apply to forensics in analytical development, population genetics, statistical interpretation of evidence, and in quality assurance. Directly involved in developing quality assurance (Quaid-i-Azam) standards for the forensic DNA field. Testified in over 200 criminal cases in the areas of molecular biology, population genetics, statistics, quality assurance, and forensic biology, such as the Scott Peterson Case.
Advisor to New York state in the effort to identify victims from the World Trade Center attack. Leader in the forensic applications on bioterrorism and is developing a new field known as microbial forensics. One of the architects of the CODIS National DNA database, which maintains DNA profiles from convicted felons, from evidence in unsolved cases, and from missing persons.
Development of analytical assays for typing a myriad of protein genetic marker systems. Design of electrophoretic instrumentation. Development of molecular biology analytical systems to include RFLP typing of VNTR loci and polymerase chain reaction-based SNP essays, VNTR and STR essays, and direct sequencing methods for mitochondrial DNA.
Design of image analysis algorithms.
