Greatest Achievement(s): Throughout 2016, toXcel’s Life Sciences division continued to advance its services by applying its scientific and regulatory expertise to support our clients’ introduction of innovative pharmaceuticals, veterinary products, antimicrobial delivery systems and sustainable reduced-risk plant protection products into North American and European markets.  The Life Sciences division currently has in-house capabilities to provide technical and regulatory expertise covering a broad range of environmental and human health issues.  In addition, toXcel continues to expand its forensic services through its analytical exposure and risk assessment skills in determining potential effects of human exposure to hazardous chemicals.   In March of 2017, our US and UK toxicology staff held an exhibit that highlighted their professional capabilities at the three-day ToxExpo event during the Society of Toxicology’s 56th Annual Meeting, which attracted nearly 7,000 delegates from all over the world. 

Over the past two years, toXcel has successfully assisted its clients in meeting the EPA’s public health and safety criteria for protection against mosquito vectors carrying the Zika virus.  We also continue to help our clients in obtaining market approval for hospital disinfectants effective against MRSA, Pseudomonas, HIV, and Hepatitis C, and other pathogens.

In April 2016, the toXcel Engineering and Behavioral Sciences division was awarded a small business IDIQ contract to support the National Highway Traffic Safety Administration (NHTSA) with behavioral safety research. This contract has a potential ceiling value of $7.25 million over five years. To date, toXcel has won two task orders from this IDIQ, valued at approximately $300 thousand. These task orders involve assessing the prevalence of drowsy driving and analyzing data related to child car seat safety.

toXcel was awarded several other contracts in the past year including a project for NHTSA to assess the effectiveness of seat belts on school buses; support for the National Operations Center of Excellence; several public health projects for the Norfolk and Hampton Roads areas; several projects for the Federal Highway Administration Office of Safety; and crash data analysis support for the Virginia Department of Transportation.

In late 2016 toXcel redesigned the company web site,, with a new, modern look and feel.  The new web site was designed to be user-friendly and provide easy to find information about all of toXcel’s capabilities. toXcel’s social media presence has been updated as well to be consistent with the design and wording of the web site.

In August 2016 toXcel organized a demonstration on how Connected Vehicle technologies will benefit emergency responders. This event was attended by over 100 responders and transportation professionals and featured two demonstrations: the Volvo Connected Truck and its automatic engine breaking system and Southwest Research Institute’s Emergency Vehicle Alert application.

In December 2016, Dr. Bryan Katz, vice president of Engineering and Behavioral Sciences, participated in the National Highway Transportation Safety Administration’s (NHTSA) summit, School Transportation Safety: Thinking Outside the Bus.  Dr. Katz presented updates on two projects toXcel is leading for NHTSA:  (1) Camera Enforcement of School Bus Stop Arm Violations and (2) Overview of Shoulder Belts in School Buses.
