About the Expert

Applied DNA Resources specializes in the review of forensic DNA testing performed in connection with criminal, military, and paternity cases nationwide. Founded by Dr. Theodore Kessis, Ph.D. in 1998, our goal at ADR is to provide legal professionals with the expert knowledge and tools required to evaluate the use, accuracy, and reliability of the DNA analysis performed in their cases. At ADR we're experienced in the use and interpretation of all current and past types of DNA testing employed in forensic case work. With over 20 years of experience evaluating DNA testing in criminal, military, and civil matters, we strive to determine if the highest standards and practices have been employed in the casework presented to us.

Expert's Profile

Dr. Theodore Kessis, Ph.D. - Applied DNA Resources

Applied DNA Resources (ADR) was established in 1998 by Dr. Theodore D. Kessis to meet the needs of attorneys faced with the rapid implementation of DNA technologies in criminal and civil matters. Dr. Kessis, currently serves as principal of Applied DNA Resources and is a former faculty member and graduate of the Johns Hopkins University.

A molecular biologist by training, he has provided case consultation in more than 1000 cases nationwide since 1994. He has also provided court qualified expert witness opinions at the State, Federal and Military levels in more than 70 cases involving Forensic DNA Analysis.

Dr. Kessis and ADR specializes in the review of Forensic DNA testing providing all of the resources required for the litigation of cases involving DNA testing, including case file review, trial preparation, test witnessing and court qualified DNA expert witness testimony.
