May 19, 2009 (New York, NY) - With a focus on corporate criminal defense and SEC and other regulatory matters, as well as congressional investigations, Ms. Mandelker will augment the firm's expanding Corporate Defense & Investigations Practice Group, which is chaired by former federal prosecutor Robert Cleary, who, since joining the firm in 2002, has been involved in many of the country's most high-profile corporate investigations, SEC-related matters and white collar cases. 

"Sigal's depth and breadth of experience is impressive by any measure," said Mr. Cleary. "As we continue to see an increase in regulatory actions against a wide range of companies and individuals, she is joining our team at an ideal time. Her ability to navigate this rapidly evolving environment will further strengthen our growing, talented team of lawyers." 

Most recently, Ms. Mandelker served as Deputy Assistant Attorney General in the Criminal Division of the Department of Justice, where she oversaw four major sections, including Computer Crime and Intellectual Property, co-chaired a US-China law enforcement working group focused on developing multi-national intellectual property investigations and prosecutions and testified before Congress numerous times on matters of criminal law. Before that, she was Counselor to the Secretary of the Department of Homeland Security, advising on operational, legislative and regulatory matters concerning law enforcement, immigration, intelligence, national security and information sharing. 

Earlier in her career, Ms. Mandelker was a counsel to the US Deputy Attorney General and an Assistant United States Attorney in the Southern District of New York, where she prosecuted numerous cases involving healthcare fraud, money laundering, alien smuggling and document fraud, among many others. A graduate of the University of Michigan, she earned her law degree from the University of Pennsylvania Law School.

Proskauer Rose in recent years has added several distinguished lawyers to its Corporate Defense & Investigations Practice Group, including: Dietrich Snell, the former New York Deputy Attorney General; Mark Harris, a former Supreme Court clerk and Assistant United States Attorney for the Southern District of New York who was part of the Proskauer team that successfully argued the recent precedent setting Supreme Court case 14 Penn Plaza LLC, et al. v. Steven Pyett, et al; and William Komaroff, another former Assistant United States Attorney in the Southern District of New York.
