In response to a lack of support and spaces for Black artists in Memphis, Merriweather, working alongside Frank D. Robinson Jr., Vitus Shell, and Jerry and Terry Lynn (or Twins) created the NIA Artist Collective in 2001.[5][6] He worked as a curatorial director at the Martha and Robert Fogelman Galleries at the University of Memphis.[2][4]
In his early career he worked in painting and sculpture.[7][8] Merriweather's collage art is often made from fashion magazines and advertising.[4][9][10] He uses images that focus on racial prominence, and systems that perpetuate social privilege, and then the images are re-contextualized in the collage with the goal of dismantling stereotypes and confronting institutional racism.[4][11] He has exhibited his work at the Zachęta National Gallery of Art in Warsaw, Poland.[4] His work is in the museum collection at the Birmingham Museum of Art.[12]
