Arpad Vass

Arpad Alexander Vass (born August 30, 1959) is a research scientist and forensic anthropologist based at the Life Sciences Division of Oak Ridge National Laboratory (ORNL), in Oak Ridge, Tennessee. He is also adjunct associate professor of Forensic Anthropology, a program of the University of Tennessee's Law Enforcement Innovation Center located in Knoxville, Tennessee.
Vass is the son of a Hungarian immigrant. He grew up in Arlington, Virginia, where he graduated from Yorktown High School in 1977. He is married to Victoria Ann Longo and they have two sons.

In 1980, Vass obtained the Antarctic Exploration certification from Scripps Institution of Oceanography. The following year, he earned a Bachelor of Science degree in Biology from Virginia Tech. In 1984, Vass earned a Medical Technology degree from Fairfax Hospital. He earned a Masters of Science degree in Forensic Science from Virginia Commonwealth University in 1989, and he obtained his PhD from the University of Tennessee in anthropology.

Vass is developing a forensic science technique called "decomposition odor analysis", or "DOA", which he claims will help to identify the over 400 body vapors which emanate from a decaying and decomposing human body. A database of such vapors would in theory enable the Federal Bureau of Investigation's search teams and cadaver dogs (Human Remains Detection dogs) to detect the location of remains of human beings. The database is a part of the University of Tennessee Anthropological Research Facility. These dogs train in the same method as narcotic dogs can sniff out graves of buried human remains.

Vass has also put forward a proposal to search out human remains with the use of a fly with a tracking chip.

Vass is developing a forensic tool to help detect and uncover forensic cases. The Forensic Anthropology Facility, located behind the UT Medical Center in Knoxville, affords scientists with bodies which have been willed to the study of forensic science and research. The molecular signature of body decomposition odor may be detected by analytical equipment or electronic body sniffer which is being researched by Vass.
