ASA has been providing forensic analysis services for 25 years, starting in 1986.  Service areas include assignments in locations  ranging from Fairbanks, AK to Christainsted, St Croix, USVI for over 1200 case investigations.

Principal engineer, Bill Rosenbluth is a Fellow of the American Academy of Forensic Sciences (AAFS) and is a certified Diplomate of the International Institute of Forensic Engineering Sciences (D-IIFES).  He also holds memberships in the Society of Automotive Engineers (SAE), the American Society of Testing and Materials (ASTM),  the Institute of Electrical and Electronic Engineers (IEEE), the IEEE Computer Society. 

Fred H. Chandler, Jr.  works with Bill as an Associate of ASA.   Fred operates a 14 bay repair service in Herndon, VA, and is a ASE  Master Technician (Certifications A1 - A9 + L1) who specializes in difficult-to diagnose-and-repair  vehicle problems.  He complements Bill's analysis skills with practical methodology in examining accident vehicles and in retrieving  EEPROM data from various EDRs.

Over the past 25 years, at various IEEE, AAFS, NAFE, CDR-Summit and attorney group meetings, he has presented more than 60 papers dealing with automotive engineering investigations and data analysis.  He has also co-instructed a continuing education short course on the Analysis of Vehicle Injury Mechanisms and Introduction to Air Bag Systems and has chaired technical sessions.  He has authored two books concerning methods and procedures for EDR data retrieval and analysis;   Investigation and Interpretation of Black Box Data in Automobiles, jointly published by ASTM and SAE in June 2001 and Black Box Data from Accident Vehicles, published by ASTM  in November 2009.   He is author of the article on Event Data Recorders in the Encyclopedia of Forensic Sciences, 2nd Edition, 2013,  and he authored an article in Forensic Magazine concerning Collection of Black Box Data for Crash Investigations.  Lastly,  a paper summarizing his work on low-speed rear-end impacts and occupant stress parameters (using manikins and human volunteers) was published in the Journal of Forensic Sciences. 

His technical contributions were recognized by the AAFS where he was presented with the Andrew H. Payne Jr. Special Achievement Award for Pioneering New Procedures, Outstanding Professional Performance & Outstanding Forensic Engineering Leadership in February, 1999.  Mr Rosenbluth was chairman of ASTM E30.05, WK 4150, ASTM Standards Development, E2493-07 Standard Guide for the Collection of Non-Volatile Memory Data in Evidentiary Vehicle Electronic Control Units.  That Standard Guide, developed by participants from Industry, Government and Private sectors, under his leadership, was approved and published by ASTM, April 2007.
