Aydin was born in Atlanta, Georgia. He attended the Lovett School in Atlanta, Georgia, earned a Bachelor of Arts from Trinity College and a Master of Arts in public policy from Georgetown University.,^[3][4]

After college, Aydin served as District Aide to Representative John B. Larson (D-CT) and as Special Assistant to Connecticut Lieutenant Governor Kevin Sullivan.

In 2007, Aydin began working for Georgia congressman John Lewis. In the summer of 2008, while on Rep. Lewis' reelection campaign, Aydin learned that Lewis had been inspired as a young man by a classic 1950s comic book, Martin Luther King and the Montgomery Story. They discussed the impact that comic books can have on young readers and soon Aydin had the idea that Lewis should write a comic book about his time in the civil rights movement. Aydin eventually convinced Lewis, who accepted on the condition that Aydin write the comics with him.

Aydin wrote his graduate thesis on the history and impact of Martin Luther King and the Montgomery Story. Until 2012, no history of Martin Luther King and the Montgomery Story had been written, and most versions of how the comic was created listed Al Capp as the actual creator. As part of his graduate degree at Georgetown University, Aydin wrote the first long-form history of The Montgomery Story as his graduate thesis. With the help of Carlow University Professor Dr. Sylvia Rhor and comic book icon Eddie Campbell, Aydin established most of what we know about the comic's creation and use. In August 2013, Aydin published a shortened version of his thesis as the feature article in Creative Loafing's award-winning "Future of Nonviolence" issue, which was guest-edited by Lewis and Aydin.^[5][6]

Aydin has appeared as a guest on The Rachel Maddow Show, Morning Joe, National Public Radio, CBS This Morning, CNN, and the BBC.

Aydin served as Digital Director & Policy Advisor to Representative Lewis in his Washington, D.C. office until Lewis's passing in 2020.

In August 2013, Top Shelf Productions published the first book in the March trilogy, a black and white graphic novel about the Civil Rights Movement, told through the perspective of Lewis, written by Lewis and Aydin, and illustrated and lettered by Nate Powell.^[7] The book had its genesis in Lewis' 2008 reelection campaign, when Lewis told Aydin about The Montgomery Story and its influence on the civil rights movement.^[8] Aydin, who had been reading comics since his grandmother bought him a copy of Uncanny X-Men #317 off a Piggly Wiggly spinner rack when he was eight years old,^[9] found a digital copy of the book on the Internet and spent years tracking down an original print copy on eBay. The Montgomery Story directly influenced on the creation of March.^[10]

President Bill Clinton has said of Congressman Lewis that, through March, "he brings a whole new generation with him across the Edmund Pettus Bridge, from a past of clenched fists into a future of outstretched hands." Apple CEO Tim Cook has said that March is "a very unique way to present what is probably the most important story of my entire lifetime. My hope is that everyone reads this, and I would love to see the day that it is required reading in every school."^[11]
