Biography

Mr. Ristenbatt holds Bachelor of Science in Biochemistry (Lebanon Valley College) and a Master of Science in Forensic Science (John Jay College of Criminal Justice/CUNY). Dr. Peter R. De Forest mentored his graduate thesis research, An Evaluation of Pyrolysis/Supercritical Fluid Chromatography for the Individualization of Polyolefins.

In 1990, Mr. Ristenbatt accepted a position at the New York City Office of Chief Medical Examiner in the Department of Forensic Biology. His duties included serological and DNA (HLA-DQ?) analysis of physical evidence recovered in homicide and sexual assault cases. In 1995, he was promoted to a supervisory position. As such, Mr. Ristenbatt was responsible for the validation, implementation, and supervision of FT-IR analysis of polydimethylsiloxane (PDMS), a lubricant used in condom manufacture. He has also received training in the analysis of gunshot residue (GSR) by scanning electron microscopy and energy dispersive X-ray analysis (SEM/EDX). Since 1991, Mr. Ristenbatt was responsible for the scientific analysis and reconstruction of crime scenes, production of reconstruction reports, and expert testimony in the five boroughs of New York City. In 2000, Dr. Robert C. Shaler formalized these operations into the Medical Examiner Scientific Assessment and Training Team (MESATT). Mr. Ristenbatt was the team supervisor of the MESATT. In 2003 the team changed its name to the Forensic Analysis and Reconstruction Unit (FARU). Mr. Ristenbatt supervised this team until his departure from city service in 2006. This scientific team examined and analyzed crime scenes with an end goal of reconstruction and it also provided training to law enforcement personnel in areas of biological evidence collection, bloodstain pattern analysis, crime scene/incident reconstruction, and forensic photography.

Mr. Ristenbatt holds certifications by the International Association of Identification (Senior Crime Scene Analyst) and the American Board of Criminalistics (Diplomate - Criminalistics) and he is a Fellow of the American Academy of Forensic Sciences. He has worked on over 300 reconstruction cases and has testified approximately 50 times (25 in the area of crime scene reconstruction). Mr. Ristenbatt, with others, has instructed over fifteen 40-hour bloodstain pattern analysis courses for personnel from agencies including the NYPD Crime Scene Unit, FBI Evidence Response Team (Newark, NJ), New Jersey State Police, New York State Police, and other jurisdictions.

Mr. Ristenbatt has also been an Adjunct Lecturer at Pace University (Westchester) and John Jay College of Criminal Justice/CUNY in an undergraduate/graduate criminalistics laboratory course and undergraduate laboratory courses of forensic chemistry and introductory forensic science. In 2006, he accepted his current position with the Forensic Science Program at the Pennsylvania State University.
