Joseph Alexis, a 25-year veteran of the Brooklyn District Attorney’s Office and the head of its red zone trial bureau, has been promoted to chief of the office’s trial bureau, according to an internal memo released Monday.

The DA’s office divides Brooklyn into five color-coded trial zones; the red zone encompasses neighborhoods on the eastern edge of Brooklyn, including East New York, Cypress Hills and Canarsie, as well as neighborhoods just east of downtown Brooklyn.

Alexis now will oversee all trial zones, as well as some specialized trial bureaus, and serve as a liaison between his office, members of the community and other law enforcement agencies.

His notable cases include that of former New York City police officer Peter Liang, who was found guilty of manslaughter for the shooting of Akai Gurley in the stairwell of an East New York housing project.

Acting Brooklyn Supreme Court Justice Danny Chun reduced Liang’s conviction to criminally negligent homicide and sentenced him to five years of probation and 800 hours of community service. Liang is appealing the conviction; the Brooklyn DA is appealing the reduction of his conviction.

Alexis also worked on the prosecution of former state Supreme Court Justice Gerald Garson, who was convicted in 2007 of taking bribes.

Alexis is also this year’s recipient of the New York City Bar Association’s Thomas E. Dewey Medal, which is awarded each year to an outstanding prosecutor from one the city’s five DA’s offices or from the Office of the Special Narcotics Prosecutor.

The award will be presented at 6 p.m. Tuesday in a ceremony at the city bar, at 42 W. 44th St. in Manhattan. A reception will follow.
