Dr. James Y. Tong (Professor Emeritus)
Chair, Forensic Chemistry Advisory Committee
Dr. James Y. Tong (Professor Emeritus) received his B.S. (1950) and M.S. (1951) from UC Berkley and his Ph.D. from the University of Wisconsin. He joined the faculty at Ohio University in 1957. In 1976, he received approval by the Ohio Board of Trustees for the B.S. in Forensic Chemistry program. At this time, he also created a new statewide organization with all of the crime directors in Ohio, and named it the Forensic Science Institute of Ohio.

Between 1976 and 1997 Dr. Tong advised all of the forensic chemistry majors at Ohio University, graduating 150 students.

He began, and still organizes, the annual Women in Science and Technology (WISE) Program and the Ohio Chemistry Contest. Dr. Tong established an endowed scholarship for forensic chemistry students, the James Y. and Harriet Tong Forensic Chemistry Scholarship. He continues to take every graduating senior to dinner to celebrate their achievements.

Dr. Hao Chen
Assistant Professor of Chemistry and Biochemistry
Mass spectrometry is a fascinating forensic analytical technology used for measuring the molecular mass of a sample, which can be applied in the qualitative and quantitative determination of matter. The current research of Dr. Hao Chen focuses on the development of new mass spectrometry instrumentation such as liquid sample desorption electrospray ionization mass spectrometry (liquid sample DESI-MS) and the hyphenated electrochemical mass spectrometry (EC/MS) that could be used for detecting analyte compounds in situ with no or little sample preparation. Therefore, it could find extensive applications for chemical detection in crime scenes, environment and security sites.

Dr. Peter de B. Harrington
Professor of Chemistry and Biochemistry Programs
Dr. Harrington teaches the forensic chemistry capstone class or lab, upper-level analytical chemistry classes and graduate-level classes in separations and chemometrics. Dr. Harrington directed the BS program from 2004-2009.

Dr. Harrington received his undergraduate degree in chemistry from Randolph-Macon College (Ashland, VA) and his PhD from the University of North Carolina-Chapel Hill in Chemometrics.  His research area is chemometrics applied to mass spectrometry and ion mobility spectrometry.

Dr. Harrington has authored or coauthored more than 100 peer-reviewed publications and has given numerous plenary lectures at international conferences. He serves on the editorial advisory board of several journals including Analytica Chimica Acta, Talanta, and International Journal of Spectroscopy.

Dr. Scott Moody
Associate Professor of Biological Sciences
Dr. Moody majored in both anthropology and biology as an undergraduate at Harvard University then earned a MS and PhD in Zoology at the University of Michigan.  This diverse education has prepared him for research and teaching in biostatistics, physical anthropology, human (medical) anatomy, entomology, systematic and field botany, historical geology, paleontology, microscopy, animal behavior, vertebrate natural history and evolutionary taxonomy. 

He teaches the forensic biology class (BIOS 3640) which incorporates lab topics from the above academic disciplines. He has supervised several undergraduate students doing independent research involving forensic biology and has identified hairs and fibers for several wildlife groups. Moody serves as an Associate Editor of the Austin Journal of Forensics and Criminology.


Dr. Nancy Tatarek
Associate Professor of Anthropology
Dr. Tatarek supports the program by teaching tech forensic anthropology class (ANTH 4470), and blood, bones and violence (ANTH 4480). Dr. Tatarek has won several teaching awards while at Ohio University.

Dr. Tatarek's PhD is from Ohio State in Biological Anthropology and her research focused on skeletal biology. She has completed numerous training courses in forensic anthropology and has been assisting Central Ohio law enforcement with casework for 12 years.  She is the Consulting Forensic Anthropologist for the Franklin County Coroner's Office. As her time allows, she holds independent lab hours each quarter for a small number of students to study osteology and skeletal analysis on an in-depth basis.

Dr. Sonja Rawn
Assistant Professor of Law Enforcement Technology
Sonja Rawn, B.S., J.D., teaches law, ethics and forensic science related classes at the Athens (Forensic Chemistry Program) and Chillicothe (Law Enforcement Technology Program) campuses of Ohio University. She has been employed with Ohio University since January 2006, first as an adjunct instructor and currently as an Assistant Professor of Law Enforcement Technology (March 2012). Sonja is a graduate of the Ohio University Forensic Chemistry Program and has a Juris Doctor from Capital University Law School. She has been employed at the Ohio Division of State Fire Marshal Forensic Laboratory for over seventeen years. During that time she has served as a Chemist, Laboratory Chief and currently as a part time Quality Manager. The balance of her years of Forensic Science employment was spent at the Franklin County Coroner’s Office (14.5 years) where she served as an Assistant and finally as an Associate Toxicologist. Sonja is a member of the American Academy of Forensic Science, The Ohio State Bar Association, The Southern Ohio Association of Fire and Arson Investigators, and the Forensic Science Institute of Ohio.

Dr. James McKean
Associate Professor of Law Enforcement Technology (Chillicothe campus)
Prof. McKean directs the LET program at the Chillicothe campus and teaches numerous LET classes on the Chillicothe and Main campuses. He earned an Associate of Applied Science degree in Law Enforcement Technology and a Bachelor of Criminal Justice degree from Ohio U-Chillicothe and an MS from Ohio State University. He holds a PhD in counseling and higher education at Ohio U.

Prof. McKean brings valuable experience to our program: he served as the Grove City Chief of Police for 13 years and lectured at the Chinese University of Hong Kong for 3 years.
