In 2006, Dr. Braunschweiger and Dr Mike Fallon at the Atlanta VA extended their 3 year collaboration by adapting the VA’s basic animal welfare training program to the CITI presentation paradigm. In 2010, more than 30,000 people completed approximately 65,000 lab animal care and use courses on the CITI platform. The CITI Lab Animal Care and Use development team is headed by Dr. Michael Mann, formally the Chair of the IACUC at the University of Nebraska Medical Center. The CITI Program, directed by Dr. Braunschweiger and hosted by University of Miami IT, now provides a multi-language, customizable, web based, research ethics education experience to learners at more than 1530 organizations around the world. Dr. Braunschweiger has served as a study section reviewer for the NIH and is currently funded by the Department of the Navy, the Department of Energy the ORI/DHHS and by the NIH/Fogarty International Center for various research ethics education projects in the US and in Latin America.
