Although it’s often unintentional, faculty can seem intimidating. So, reaching out to a professor with questions can be quite a challenge for some students. For others, not so much.

Zachary Axel is a great example. Reaching well beyond Georgia Tech faculty, he started sending “cold call” emails in 2023 to A.M. Turing Award winners and other computing luminaries.

The emails shared Axel’s vision for a virtual platform that would enable Georgia Tech students and faculty to connect with some of the most distinguished minds in computing. 

The first to accept was Moshe Vardi, a distinguished professor of computer science at Rice University and recipient of the 2020 AAAI Allen Newell Award and several other ACM awards. Vardi’s January 2024 presentation was a hit and served as a template for what grew to become the Turing Mind Series at Georgia Tech.

Three years and nearly two dozen emails later, the series is wrapping up later this month, hosting its 22nd event and its 15th Turing Award winner.

Registration is open for the final session of the Turing Mind Series on March 30, featuring 2019 Turing Laureate Patrick Hanrahan, widely renowned for his enduring contributions to 3D computer graphics.

“There are approximately 70-75 living Turing Award winners. I am proud to say that we have hosted roughly 20% of them for the Turing Minds Series,” said Axel, a former Online Master of Science in Computer Science (OMSCS) student.

“Fifteen felt like the right number to end on. We set out to connect Georgia Tech students and researchers with Turing Laureates, and we did exactly that. Mission accomplished."

As one might guess, Turing Award winners don’t receive a lot of unsolicited emails from students. Vinton Cerf, a 2004 Turing Award winner, says people typically hesitate to engage without some form of endorsement or introduction.

“What is notable about Zachary’s initiative is that he undertook to ‘cold call,’ well, ‘cold email,’ Turing Award recipients to ask them to participate in the program,” said Cerf, who, along with fellow 2004 Turing Laureate Robert Kahn, was instrumental in the pioneering development of fundamental internet communication protocols.

“It is a measure of his confidence and optimism that he succeeded in persuading Turing awardees to engage in the speaking program. Zachary did not hesitate and, in some ways, that may be why he was so successful,” said Cerf.

Axel credits GT Computing Dean Emeritus Zvi Galil with encouraging him and offering guidance along the way.

“Zach is amazing, and he has a lot of chutzpah,” said Galil. “The Turing Minds Series is a remarkable achievement and has become the premier global speaker platform for computer science luminaries.”

Axel thinks he was successful early on for two reasons: he kept it simple, and he used his Georgia Tech email address. He emailed the first five Turing Laureates from the perspective of a student hungry for knowledge.

“I simply asked the Laureates I reached if they would give 30 minutes of their time to virtually present to me and my GT classmates,” said Axel.

He says he would thoroughly research each winner so he could reference a presentation, paper, or another specific aspect of their work in his email. “I did my homework. I made it very easy for them to say yes.”

Axel’s request emails also offered the Turing Laureates –and the Nobel Prize Laureates who were also invited– the option of sharing a presentation or participating in a Q&A. It was this decision to offer a Q&A format that led to one of the most significant moments of the Turing Mind Series for Axel.

“That's how we got legendary 1974 Turing Laureate Donald Knuth. Known for being extremely selective in accepting speaking invitations, he specifically stated that the offer to do a Q&A format was the reason he accepted,” said Axel.

“I also don't think it hurt that the email was coming from an @gatech.edu address, as the Georgia Tech name offered us significant credibility.”

Knuth, widely regarded as the “father of algorithm analysis,” and renowned for his foundational work, The Art of Computer Programming, joined the Turing Minds Series in October 2025 as its 12th guest.

“Thanks so much to you and Parsa for honoring me with an invitation to speak in the online ‘Turing Minds’ series at Georgia Tech,” Knuth said in a note written to Axel.

“It was lots of fun for me this morning to try to answer the excellent questions posed by so many of the viewers.”

Parsa Khazaeepoul is also a former OMSCS student and the co-founder of the series. Axel says that Khazaeepoul’s technical expertise led to the success of the series’ virtual platform.

“Parsa built the series website and managed all of the challenges of hosting and scaling a platform that has impacted to date 4,000+ students and faculty from Georgia Tech and throughout the world.”

The Turing Minds Series at Georgia Tech hosted its first speaker in January 2024. The final installment is scheduled for March 30 at 1 p.m.

But this isn’t the end of the series. Live video recordings of each of the soon-to-be 15 events in the series are available at https://www.turing.rsvp/.

Beyond the website, Axel says the Turing Minds Series is partnering with the ACM, the creators and distributors of the A.M. Turing Award. The goal is to integrate the series into the ACM ecosystem, where it will be accessible to the ACM’s 110,000 student and professional members in more than 170 countries.

"We had a lot of people reach out to us to thank us for what we were doing. Knowing that students left these conversations seeing what's possible in computer science, that meant everything to us," said Axel.
