INSTRUCTIONAL DEVELOPMENT
Mr. Marks developed the three-level national Homeland Security Certification Program for the American College of Forensic Examiners, as well as the Masters Program in Homeland Security for the Universitá Telematica Guiglio Marconi in Rome, Italy.

Outside the realm of counterterror and homeland security, Mr. Marks led the development of an interactive literacy training program designed to address a specific range of cognitive learning disabilities in children. The program was based on a cognitive analysis program initially developed to screen candidates for US bomber crews.
