Meet Eshan Chattopadhyay, Indian-Origin Cornell Professor, IIT Grad, Awarded Gödel Prize
Last Updated: From IIT-Kanpur to Gödel Prize: Eshan Chattopadhyay's work reshapes randomness and complexity theory. Eshan Chattopadhyay, an Indian-origin computer scientist and associate professor at Cornell University, has won the 2025 Gödel Prize. The Gödel Prize is one of the top honours in theoretical computer science. He shares the award with David Zuckerman of the University of Texas at Austin for a groundbreaking paper that tackles a long-standing challenge in computing: how to generate high-quality randomness from unreliable or weak sources. The research paper, titled 'Explicit Two-Source Extractors and Resilient Functions", was first presented in 2016 at the ACM Symposium on Theory of Computing, where it won the Best Paper award and was later published in the Annals of Mathematics in 2019. Chattopadhyay's work dives into randomness extraction, a crucial area in computer science and cryptography. One may think of it like this: if one had two rigged coins, this method would still find a way to give them fair, unpredictable outcomes. Though it might sound abstract to the uninitiated, its real-world impact is massive. Good randomness is the foundation of everything from secure communications and encryption to complex algorithms and data privacy. Without it, modern digital infrastructure becomes fragile. The paper's ideas have helped reshape how researchers approach pseudo-randomness, complexity theory and secure system design. Chattopadhyay, who did his BTech from IIT-Kanpur in 2011 and PhD from the University of Texas, has also held prestigious research positions at the Institute for Advanced Study in Princeton and the Simons Institute in Berkeley. Reacting to the award, he told Cornell it felt 'surreal and gratifying" to see his work recognised on such a global stage, as reported by LiveMint. The prize is jointly awarded by Special Interest Group on Algorithms and Computation Theory (ACM SIGACT) and the European Association for Theoretical Computer Science. The prize includes a $5,000 award. It recognises papers that have made lasting contributions to the field, both in theory and long-term relevance.

Who is Eshan Chattopadhyay? All about Indian-origin professor awarded prestigious Godel Prize
Eshan Chattopadhyay, an Indian-origin computer scientist and associate professor at Cornell University, has received the 2025 Gödel Prize—one of the highest recognitions in the field of theoretical computer science. He shares the award with David Zuckerman of the University of Texas at Austin for their influential research on randomness extraction—an area crucial to encryption, cybersecurity, and algorithm design. 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.

The result is still unpredictable, but not evenly so. Randomness extraction is the process of turning that weak, messy randomness into clean, strong, and fair random bits — like those from a perfect coin toss. The technique generates truly random numbers using less computing power than previous approaches, potentially boosting security for everything from credit card payments to military IS THE INDIAN-ORIGIN PROFESSOR?Chattopadhyay completed his PhD at UT Austin before joining Cornell University, where he now works on pseudorandomness, circuit complexity, and communication complexity, according to the University of addition to the current honour, Chattopadhyay received a Sloan Research Fellowship in 2023, a National Science Foundation (NSF) CAREER award in 2021 and an NSF Computer and Information Science and Engineering Research Initiation Initiative award in conducted postdoctoral work at the Institute for Advanced Study at Princeton and the Simons Institute for the Theory of Computing at the University of California, earned his PhD at the University of Texas at Austin in 2016 and his BTech at the Indian Institute of Technology (IIT) Kanpur in 2011, both in computer science, according to Cornell work was originally published in the proceedings of the Association for Computing Machinery (ACM) symposium on Theory of Computing (STOC) in 2016, where it received the Best Paper award, and later in the Annals of Mathematics in 2019, according to Cornell applications in complexity theory and cryptography, techniques introduced in the paper opened new approaches to long-standing problems in pseudo-randomness and explicit his happiness, Chattopadhyay said, "This recognition is truly an incredible honour.

India needs its own automotive design identity, says Avik Chattopadhyay
As India scales up its ambitions in manufacturing and mobility, a senior industry voice has called for an urgent rethinking of the country's approach to automotive design. Speaking at the foundation stone-laying ceremony of the Indian School for Design of Automobiles (INDEA) in Pune, Avik Chattopadhyay , Chairperson of the XLRI Centre of Automobile Design & Management , said India needs to turn towards its cultural roots to establish its own identity in the global automotive landscape . 'The future of the institute rests on a single objective--to prepare world-class design talent that is productive from day one, whether in an automaker, a studio, or a research organisation,' Chattopadhyay said. The long-term goal, he added, is to create a design DNA that instinctively evokes Indian identity--even without a brand badge. Building a design DNA: From imitation to identity Drawing comparisons with Italy and Japan, Chattopadhyay pointed out how national design identities are often deeply rooted in cultural expression. 'There is something quintessentially Italian about a Benelli or a Maserati, just as there is something uniquely Japanese about a Honda NSX. But ask yourself--can we say the same for an Indian design? Not yet,' he said. He believes that Indian mobility design can draw inspiration from the country's rich heritage in craft, architecture, and visual culture. 'I've often wondered, why can't we use textiles like jacquard, zardozi, kantha, or ikat in car interiors?' he asked. 'These are deeply Indian, yet subtle. That's the kind of embedded identity we must aim for.' Chattopadhyay was candid in highlighting systemic gaps in design appreciation in India. 'We are blind to design as a people--look at how we construct our streets and public spaces. We don't think of design as integral,' he said. Even in domestic interiors, he observed, India often borrows from Western visual vocabularies that don't suit local sensibilities. 'Our postures, our body frames, are not meant for European furniture.' For India to take design seriously, he said, the country needs not just talent, but an entire design-aware ecosystem. 'There is no Make-in-India without Design-in-India,' he said. 'Design is what creates value. Manufacturing brings revenue, yes--but the delta, the differentiator that takes you from a $5 trillion to a $20 trillion economy, is design.' Studio-led learning with industry at the core The new design school, INDEA, will launch its first 25-student batch in 2026 as part of a 24-month master's programme. Structured as a hybrid of design and management, the curriculum will integrate studio learning with business thinking. 'A designer must understand not just form and function, but also consumer behaviour, product strategy, and market positioning. That's how you add value,' Chattopadhyay explained. The institute will operate in close collaboration with the mobility industry . Students will be taught primarily by working professionals, designers and decision-makers from global automotive brands and studios. 'They bring with them real-world experience--they've made mistakes, adapted, succeeded. That's something you can't find in textbooks,' he said. Rather than traditional classrooms, the school will function as a live studio--complete with sketching spaces, CAD workstations, clay modelling, and prototyping labs. 'Your final test, as a student, will be to build a working prototype. That's when we'll know if you're really worth it,' he noted. While the initial focus will be domestic, Chattopadhyay said the global appeal of the school, especially with a visiting faculty of seasoned international designers — will likely attract foreign applicants over time. While acknowledging that developing a national design identity is a long-term endeavour, Chattopadhyay is optimistic about India's potential. 'Others may have taken 50 years, we can do it in 25 or 30. The Chinese are doing incredible things. The Brazilians built the Embraer jet. India must believe it can do the same in automobiles,' he said.
