After completing Makerere University with a BA in Fine Art in 1990, Taga Nuwagaba embarked on his career and has painted since using watercolour and oil. His favourite subject has always been wildlife and the human figure. He has a passion for culture and the people he prefers for his subject are usually from rural Uganda.

His choice of the Black Madonna and child as a continuous theme in his career does not only show his concern for the African woman but it is a depiction of the real hardship she endures.He was inspired to become an artist by his grandmother Kateta who was an accomplished artist in her own right.

Taga has worked with many conservation and wildlife groups in Uganda like the Jane Goodall Institute in Ngamba Island Chimpanzee Sanctuary, Uganda Wildlife Education Centre, Ecotrust, and African Wildlife Foundation. His wildlife works of primates and moths have appeared on Uganda stamps. Uganda Tourist Board commissioned him to make a mural depicting thirty five Uganda 's favourite bird species to represent Uganda in the International bird-fairs abroad.
