President of CBR Global Advisors Celina Realuyo who is also an assistant professor on counter terrorism, talks to the TEDXSF audience at the California Academy of Sciences yesterday afternoon. She encourages people to set up plan of attacks for potential risk scenarios in our lives, whether it's in management or in our personal lives.

Her orientation comes from serving as a former U.S. diplomat, a foreign policy maker under the Bush and Clinton Administration, and a professor of counterterrorism and national security.
