Bio

Dr. Prinz is a Professor in the Science Department and the director of the Master of Science in Forensic Science Program at John Jay College of Criminal Justice in New York City. Her expertise is in forensic DNA analysis. After working as casework analyst and laboratory director at the Institute of Legal Medicine in Cologne Germany and the Office of Chief Medical Examiner in New York City Dr. Prinz has more than 30 years of DNA casework experience. Over the years she and has served with several organizations promoting best practices in forensic science on the state, federal and international level. Her past research focussed on assays enhancing DNA casework capabilities, like Y-chromosome specific DNA testing. Current research interests include the optimization of touch DNA recovery, typing and interpretation.

Research Summary

Many of our research projects pertain to the optimzation of DNA analysis for contact traces. Optimization can be at the recovery and testing level, or at the interpretation step. Past research involved parallel recovery and detection of DNA and protein markers in contact traces. We are also working on a method for intergrating DNA and latent print processing for paper evidence. The main project is on determining the population variability of individual shedding propensity, or how much DNA people leave behind when touching a substrate.
