Manuel Pita, who goes by the alias Sejkko, is a fine arts photographer and cognitive scientist based in Lisbon. ^[3]

Pita was born and raised in Venezuela to Portuguese parents who came to the country during the oil boom during 1970s. He would move back and forth between his native country and parent's home country of Madeira. When he arrived in college, he had a choice between pursuing art or science, both subjects that he showed extreme promise in. He decided to study Computer Science and then went on to complete his PhD in Artificial intelligence and Cognitive Science from the University of Edinburgh in 2007. Following his PhD, he spent a number of years doing postdoctoral work in Complex Systems, trying to understand how nature processes information. ^[2]

After finishing his studies, Pita decided to go full circle and return to art.

Under his alter-ego Sejkko, Pita launched his fine arts photography Instagram account in 2012. The account grew in popularity and was featured in magazines such as Wired, World Photography Organisation, The Telegraph, and The Guardian. Sejkko is noted for his Minimalist style that and uses soft, pastel tones that embody detail and character. In addition, Sejkko tries to bring vibrancy as well as symmetry to his work. ^[2]

Sejkko's most well-known collection was his Lonely Houses Series which captures simple houses on the tropical Portuguese countryside.

He tries to emphasize being whole in aloneness and the meaning of "home" in his project.
