Mayor Michelle Wu has renamed her office of economic development “Office of Economic Opportunity & Inclusion” and is appointing BECMA chief Segun Idowu to the high-profile position atop it.

Idowu, the current president and CEO of the Black Economic Council of Massachusetts, will take the reins in January as Wu’s economics chief.

Midori Morikawa, who was then-Acting Mayor Kim Janey’s chief of economic development, will remain with the city and take on a yet-to-be-named role doing neighborhood development.

“Segun Idowu has expanded our vision for what is possible when we champion inclusive business and economic development and use our city’s resources to build wealth and opportunity in every community,” Wu said in a statement announcing that Idowu would be her “Chief of Economic Opportunity & Inclusion.”

Enough people talked about Idowu himself running for mayor this cycle that he changed his name on Twitter to a declaration that he wasn’t going to run. Idowu’s BECMA’s mission is “to advance the economic wellbeing of Black businesses, organizations that support the Black community, and Black residents of the Commonwealth.”

“I am excited at the prospect of working with my colleagues in an administration keenly focused on making Boston an equitable world-class city for all,” Idowu said.

The economic development chief post is a highly influential one in the city government, running a large department in a busy business city. John Barros recently held the post for essentially all of former Mayor Martin Walsh’s seven-year tenure; Walsh appointed him to the plum position after Barros, a 2013 mayoral candidate and former head of a the Dudley Street Neighborhood Initiative, endorsed Walsh in the general election. Barros then ran for mayor again this year.
