Who is Eshan Chattopadhyay? All about Indian-origin professor awarded prestigious Godel Prize
The award was given for his breakthrough research paper titled 'Explicit Two-Source Extractors and Resilient Functions', which addresses a key challenge in computer science: how to generate high-quality randomness from unreliable sources, critical for secure computing and cryptographic systems.
Published initially at the ACM Symposium on Theory of Computing (STOC) in 2016, where it also won the Best Paper award, and later in the Annals of Mathematics in 2019, the paper introduced new techniques that have since shaped major advances in pseudo-randomness and complexity theory.
Chattopadhyay completed his BTech in computer science from IIT Kanpur in 2011, followed by a PhD at the University of Texas in 2016. He later held postdoctoral positions at the Institute for Advanced Study in Princeton and the Simons Institute for the Theory of Computing at UC Berkeley, two of the most prominent institutions in the field.
Named after legendary logician Kurt Gödel, the Gödel Prize is jointly awarded by the ACM SIGACT and the European Association for Theoretical Computer Science. It honours papers that have made lasting contributions to the field of theoretical computer science.
The research deals with randomness extraction- a fundamental concept in computer science and cryptography. It focuses on creating reliable randomness from two flawed or weak random sources, a challenge that has implications for everything from encryption systems to algorithm design.
In simple terms, imagine flipping two unfair coins and still being able to extract fair, unpredictable results. That's the essence of what Chattopadhyay and Zuckerman achieved, turning weak inputs into strong, usable randomness.
He told Cornell University that the recognition is an incredible honour. He shared that it feels 'surreal and gratifying' that the paper was placed in that category.

Ax-4: Students go orbital with Shux in live chat
1 2 Lucknow: From floating dinners to ceiling-less sleep, students at City Montessori School, Lucknow — alma mater of astronaut Shubhanshu Shukla — were treated to a rare window into life aboard the International Space Station (ISS) during a live interaction on Thursday. Speaking from orbit as part of Isro's Vidyarthi Samvad programme, Shukla — the first Indian aboard the ISS — shared anecdotes from his Axiom-4 mission journey. "The launch was powerful and unforgettable," he said, before delving into everyday life in microgravity. "There's no up or down here. We sleep secured inside sleeping bags. Otherwise, we might drift into another module! Meals, too, are tailored for space, with astronauts pre-selecting dishes they enjoy. We test different foods before launch — whatever we like, gets packed," Shukla said. Curious minds also asked about health in orbit. "We carry a medical kit and are trained to handle small issues," Shukla assured. Addressing the physical toll of space, he said: "In weightlessness, muscles weaken fast. So, we work out daily — cycling while floating and using resistance machines." Shukla's description of Earth from above drew audible gasps from the audience. "It's beautiful," he said. Also present was Gaganyaan astronaut-designate Group Captain Angad Pratap, who urged students to chase careers in science and space. "India's space future is bright. You could be the next to launch," he said, inspiring wide-eyed applause. In a separate 10-minute communication, a group of 70 students got lucky on Friday as they tuned into a HAM radio session with Shukla, who spoke to them from the ISS. At the Isro's UR Rao Satellite Centre (URSC) in Bengaluru, Shukla spoke to them about life on the ISS, the travel there, and how excited he was about his scientific experiments. He also told them that he was excited about his research work, especially those involving stem cells. The URSC communication was facilitated through the global Amateur Radio on the International Space Station (ARISS) initiative. Though 20 questions were shortlisted for Shukla, only a handful could be asked owing to time constraints. Isro did not broadcast the interaction live, but several amateur (HAM) radio operators worldwide managed to capture parts of the downlink, albeit with patchy audio. In one audible section, Shukla described the docking: "...The entire process of how the capsule approaches the station and then positions itself right in line with the docking port, and thereafter goes ahead and docks into the port... It was a very, very exciting moment for me." While details of all 70 students were not made available publicly, Mysuru-based Excel Public School said six of their licenced student HAM operators — Bhuvan PM (call sign: VU2NQH), Namasyu A (VU3IHV), Tanish Tejaswi MS (VU2ITM), Pranav CN (VU3IIC), Vishruth R (VU3IIB), and Sanat Raj G (VU3IHU) — established radio contact using ARISS ground station infrastructure. "This is a once-in-a-lifetime opportunity to apply what we've learnt in real time," said a statement from the students, who were in Bengaluru for the interaction. The school's HAM club (VU2TQA), active since 2023, does satellite tracking, antenna building and ISS signal decoding. Recognised as an Isro Space Tutor, Excel regularly conducts astronomy outreach. "It's a proud moment for our students and for India," said Mathew KG, the principal.
