Emerson College is mourning the death of a professor who was a member of the school’s community for more than 18 years.

Emerson president Lee Pelton announced the death of Robert Todd, a professor and associate chair of Emerson’s Department of Visual & Media Arts, in a statement Saturday.

A cause of death was not given.

Todd was reported missing to police Aug. 16, according to a Boston police spokesman, Officer James Kenneally.

Todd was last seen Thursday evening heading into Franklin Park, a family member said in a Facebook post Friday night.

Pelton said the school’s community expressed its “deepest condolences’’ to Todd’s wife, family, friends, colleagues, students, staff, and others who mourn Todd’s loss.

“Robert brought extraordinary talents, incredible vision and outstanding dedication to his art, and to his teaching. He inspired filmmakers of all ages at Emerson, giving generously of his time and energy to his fellow artists over the years,’’ Pelton said in a statement to the Emerson community.

Described as a “lyrical filmmaker’’ as well as a sound and visual artist on his Emerson biography page, Todd produced a series of films that were exhibited at venues and festivals around the world.

Todd also taught film production at other schools, including Boston College and the School of the Museum of Fine Arts, Boston, according to Emerson. He also had worked as an editor, sound designer, and as a producer on broadcast and theatrically released media programs.

He was also the recipient of numerous grants and awards, according to his Emerson biography.

The college’s counseling staff will be available to meet with members of the campus community during normal working hours Monday through Friday, 8:45 a.m.-5 p.m., at 216 Tremont St., 2nd floor, Pelton said.

For after-hours crisis service, call 617-824-8595, Pelton said.

Harrison Blum, Emerson’s director of spiritual life, will hold open office hours Monday from 1 to 4 p.m. in the Center for Spiritual Life, L1 Piano Row, Pelton said.

Todd’s family will welcome his friends at a celebration of his life, Pelton said. Information about that service will be released as soon as it is available, he said.
