Practice Areas
Board-Level Consulting
- Advised on a comprehensive cybersecurity risk assessment for a global enterprise, identifying vulnerabilities in their IT infrastructure, assessing potential threats, and recommending strategies to mitigate risks.

This included immediate incident response to contain the breach, conducting a thorough investigation to determine the cause and extent of the breach, liaising with legal and PR teams, and law enforcement agencies to manage external communications, and advising on long-term strategies to prevent future incidents.
Investigations
- United States v. Khattalah (Benghazi): Investigation into a terrorist attack in Benghazi, Libya, that resulted in the deaths of four U.S. citizens, including one U.S. Ambassador on Sep. 11, 2012, which included close collaboration with all agencies in the US Intelligence Community, as well as North African and Southern European security services to gather evidence, conduct witness interview/depositions, and develop working relationships. The investigation resulted in the location, capture/arrest, and prosecution of the militia leader responsible for the attack. Ultimately the case received the U.S. Attorney General’s Award for Distinguished Service and nominated for Director’s Award for Counterterrorism investigations.
- United States v. Cheibani (Mali/Niger): Investigation into the murder of Defense Attaché William Bultmeier in Niger in 2000. Two diplomats were attacked by an unknown assailant, resulting in Mr. Bultmeier’s death. The FBI NY received the case in 2011 and through diligent investigation, travelled overseas, identified witnesses, collected forensic evidence, and collaborated with intelligence services to arrest Cheibani in Mali.
