Police Commissioner Ed Davis officially announced his resignation during a 10 a.m. press conference at Boston police headquarters this morning.

Davis acknowledged that he is leaving on his own terms, after lengthy contemplation.

“Its time to try other things,” Davis said during the press conference. After accomplishing more than he could have expected, Davis added, it will be hard to stop himself from getting involved, if he sees a crime taking place.

Davis said he has been offered several “interesting opportunities,” and it will take him a couple of months to reach a decision. Davis wouldn’t comment on speculation regarding the Secretary of Homeland Security position. He did, however, confirm that he’s been offered a fellowship at Harvard University, and has always wanted a connection with the institution.

Amidst criticism about police responding faster or more efficiently to certain Boston neighborhoods, Davis urged people to look at the records for themselves.

“(Boston police) focus on where violence is occurring, not any particular neighborhood,” said Davis, noting that the department’s decisions are data-driven.

“We’re doing exactly what we should be doing.”

Davis, who rose to national prominence following the Boston Marathon bombings, praised all departments involved, saying that efforts could not have been coordinated better.

When asked to address the lack of minority promotion within the department, Davis took issue with the definition of merit, while praising his own leadership over seven years as commissioner.

“I know how to do it,” said Davis. “I can build a team.”

Davis also addressed the $2.2 million in public funds that Mayor Tom Menino has dedicated to “fix the problem.” The challenge, Davis said, would be getting members of the department to acknowledge that promotion is not just about a written exam.

“It’s about much more than that,” added Davis.

Davis is in talks with Menino to assure a “smooth transition” following his departure in 30-60 days.

Davis remained adamant that his tenure, and choice to resign, be left out of the mayoral election discussion. Suffolk County District Attorney and mayoral candidate Dan Conley, however, made a brief appearance during the press conference — held the day before the preliminary election.

“I’m personally disappointed,” said Conley, regarding Davis’ resignation. “I was looking forward to working with him for many years.”

Touching on Davis’ involvement with Boston communities, and his innovative ideas about integrating science and technology with the police department, Conley said the next commissioner will have “big shoes to fill.”

Harvard University is believed to be Davis’ preferred destination. He would not comment on any other opportunities he’s been offered.

“I’m not leaving Boston,” said Davis. “I’ll be around.
