Cognata attended the Boston Arts Academy (2006) where he majored in theatre. In 2008, Cognata made his television debut in a national commercial for Subway and performed with the poetic entertainment group called ARTiculation. The Boston Herald writes in a 2009 article, "Give the creativity and enthusiasm of this highly talented group of young poets a chance. Their performance is good enough to make even a cynic believe in the power of art." Cognata then moved to New York City and Los Angeles to obtain television roles including Julian Robbins, brother-in-law to battalion chief Wallace Boden on NBC's Chicago Fire (2018), and recurring as Tito, Lip's intern on Showtime's Shameless (2016). He appeared in Hallmark's Romance at Reindeer Lodge (2017). In addition to his work in film and TV, Cognata represented his hometown in the Edinburgh Festival Fringe (2006), where he performed the play A More Perfect Union.
