A gift to Columbia Law School from alumnus Ira Greenstein '85 honored Professor Librescu's heroism during the Virginia Tech shooting and established a professorship in his name—the "Liviu Librescu Professor of Law." This professorship is awarded at the discretion of the Dean, who seeks to appoint to the Librescu Professorship a member of the faculty with an expertise in national security or social justice. Matthew Waxman currently holds the Librescu Professorship. He is an expert in national security law and international law, including issues such as executive power, international human rights and constitutional rights, military force and armed conflict, terrorism, cybersecurity, and maritime disputes.
