Assistant Professor of Forensic Sciences

Dr. Dale K. Purcell

Dr. Dale K. Purcell, Assistant Professor of Forensic Sciences, earned his B.S. in Chemistry from Western Oregon University in 1998. He earned his M.S. in Forensic Science from John Jay College of Criminal Justice, CUNY, in 2003, his M.A. in Criminal Justice from John Jay College of Criminal Justice in 2011, and his Ph.D. in Criminal Justice with a Forensic Science Specialization from The Graduate Center, CUNY, in 2013. Dr. Purcell was employed for six years at an ASCLD-ISO accredited state forensic science laboratory where he performed duties in chemical analysis of controlled substances, crime scene investigations, and primary examinations for major crimes such as homicides, assaults, and sex-crimes.

Dr. Purcell teaches a broad range of courses in microscopy, instrumental analysis, and microanalysis of Trace Evidence, as well as, the Seminar Series to Forensic Science Graduate students. Dr. Purcell as attended in excess of 35 continuing education workshops and short-courses, and has presented numerous seminars at international, national, and regional professional scientific meeting on a variety of research topics related to Microanalysis and Trace Evidence.

Dr. Purcell was a Visiting Scientist, a program sponsored by Oak Ridge Institute for Science and Education (ORISE), at the Counterterrorism and Forensic Science Research Unit (CFSRU) in the Laboratory Division of the Federal Bureau of Investigation, Quantico, Virginia, where he performed research to develop procedures to assess province of sands using cathodoluminescence light microscopy and scanning electron microscopy with energy dispersive x-ray microanalysis. He continues to consult and perform related research on sand province in Hawaii to assist local law enforcement agencies.
