In addition to his work in the film industry, Joshi is also a professor of English at Otterbein University in Westerville, Ohio.

Abhijat Joshi was born and raised in Ahmedabad, Gujarat, in a family of professors, including his father Jayant Joshi. He completed his early education in Gujarati medium and went on to pursue higher education at Shri H.K. Arts College, Gujarat University. After completing his M.A. in English with distinction, he obtained his Master of Fine Arts degree from the Michener Center for Writers at the University of Texas at Austin. Joshi is fluent in Gujarati, as he grew up in a Gujarati-speaking environment.

Joshi's passion for writing stories and plays developed during his school days. He actively participated in annual competitions for Gujarati dramas and won multiple awards. He also had a keen interest in cricket. Before pursuing his MFA degree, he worked as a professor of English at C.U. Shah Arts College in Ahmedabad. Apart from teaching, he was involved in theatre activities and wrote numerous plays and skits in Gujarati and English.

One of Joshi's notable works is the play "A Shaft of Sunlight," which he wrote during the 1992 Gujarat riots. The play received critical acclaim, and it caught the attention of director Vidhu Vinod Chopra, leading to their collaboration on the films "Kareeb" and "Mission Kashmir." The play was later adapted as "Marmbhed" in Gujarati and performed by the UK-based Tamasha Theatre Company in collaboration with the Greenwich Repertory Company, with over 300 shows.

Joshi's writing is influenced by the teachings of Sane Guruji, a noted Marathi social reformer. His father, Jayant Joshi, a Sane Guruji scholar, introduced him to the profound concept of dharma as seen by Sane Guruji, which greatly influenced his storytelling.

In 2015, Joshi wrote the script for Vidhu Vinod Chopra's Hollywood film "Broken Horses." As of 2016, he was working on two scripts, the third installment of the "Munnabhai" series and a biopic on actor Sanjay Dutt. Joshi's contributions to the Hindi film industry have garnered critical acclaim and commercial success, and his collaboration with Rajkumar Hirani has been particularly noteworthy.
