His parents separated when he was thirteen and he returned with his father to Connecticut to attend West Haven High School, where he played football and performed in the choir.

This series of paintings and drawings visualize Hammie's effort to reshape himself and propose the possibility of a new ideal, one positioned more as a work in progress than an achievable end.

[7] On January 11, 2010 Hammie displayed selections from Imperfect Colossi and Equivalent Exchange in a solo exhibition at Stewart Center Gallery at Purdue University.

[9] Hammie returned to his studio from his Kohler residency in September 2011 and began production on paintings that question inherited visual expectations of historically marginalized people, and work to reorient how meaning is made around those bodies.

Paintings such as Aureole from 2013 feature a commanding woman rotating a reclined man's body to his side, baring his nakedness and inspecting his state of consciousness.

[14] On March 22, Hammie's Bust of an American Man [early 21st century] was displayed in the John Michael Kohler Arts Center's 40th anniversary retrospective, which featured 40 years of collected works by arts/industry residents.

[16] One of Hammie's portraits was featured in the exhibition, What's Inside Her Never Dies... A Black Woman's Legacy at Yeleen Gallery for their Art Basel Miami showcase in January 2016.

Hammie's oeuvre is defined by his ongoing engagement with the history of painting, in particular his use of allegory to implicate power structures, question systems of racism and sexism, and examine how male artists have imagined the nude.

[18] Since debuting in 2009, Hammie has dedicated his career to traditional figurative painting, investigating the pictorial, technical, and narrative practices of Western art, producing portraits that disturb the existing canon and examine critical aspects of gender and race today.

He cites Francis Bacon, Luís Caballero, Caravaggio, Renée Cox, Marlene Dumas, Lucian Freud, Leon Golub, Jacob Lawrence, Robert Mapplethorpe, and Kerry James Marshall as some of his favorite artists.
