Former DHS privacy head moves to law firm

Mary Ellen Callahan headed up the first statutorily required privacy office while at Homeland Security Department and now takes that experience to the private sector.

Mary Ellen Callahan, former chief privacy officer at the Homeland Security Department, joined the Jenner & Block law firm as a partner, the firm announced Sept. 4.

She will lead the firm's newly formed Privacy and Information Governance Practice. Jenner & Block is based in Chicago, but Callahan will work in DC.
