Dr. Mark Perlin

Mark W. Perlin, Ph.D., M.D., Ph.D.

Dr. Mark Perlin is chief scientist and executive at Cybergenetics, a Pittsburgh-based bio-information company. Dr. Perlin holds a Ph.D. in Mathematics, a Ph.D. in Computer Science, and an M.D. medical degree. He has worked on a thousand criminal cases, and the World Trade Center disaster.

For over 20 years, because of PCR copying variation, informative DNA data from millions of evidence items have been uninterpreted, misinterpreted, or inaccurately reported. Dr. Perlin solved this problem twenty years ago by mathematically modeling DNA mixtures to account for the variation.

He wrote the TrueAllele® software to translate DNA evidence into probabilistic genotypes. The statistical model has been published and extensively validated, even for complex DNA mixtures long believed to be unsolvable. His probabilistic genotyping automation has been widely adopted, used in crime laboratories, and has now become the scientific standard. Through his innovation, criminals are brought to justice and innocent people are freed.
