Panagiotis G. Ipeirotis (also known as Panos Ipeirotis; born May 3, 1976, in Serres, Greece) is a Greek-American computer scientist and the Merchants' Council Professor of Technology and Business at the New York University Stern School of Business.[5][6] His research focuses on data mining, crowdsourcing, human computation, and the economics of online information systems.[7]

Ipeirotis received the Lagrange Prize in Complex Systems (2015)[3] and the ACM SIGKDD Test of Time Award (2020).[4] His research on Amazon Mechanical Turk and crowdsourcing quality management has been discussed in publications including The New York Times, The Economist, and Bloomberg Businessweek.[8][9][10]

In addition to his academic career, Ipeirotis co-founded the AI consulting firm Detectica in 2015, which was acquired by Compass, Inc. in 2019.[11] He has also held research positions at Google (2013–2014), where he conducted research on crowdsourcing methods to improve the Google Knowledge Graph,[12][13] and at Meta's Reality Labs division (2024–2025), where he worked on machine learning deployment for wearable devices.[5][14] Ipeirotis also authors the blog "A Computer Scientist in a Business School," which has been cited in media coverage.[15][16]

Early life

Ipeirotis was born on May 3, 1976, in Serres, Greece.[2] In 1994, he won a Gold Medal at the 8th National Greek Competition in Chemistry.[17] Later that year, he represented Greece at the 26th International Chemistry Olympiad in Oslo, Norway.[18]

Education

Ipeirotis earned his Diploma in Computer Engineering and Informatics (CEID) from the University of Patras in 1999.[5] He pursued graduate studies at Columbia University under the supervision of Luis Gravano, receiving his M.Sc. in 2001, M.Phil. in 2003, and Ph.D. in Computer Science in 2004.[5]

Academic career

Ipeirotis began his academic career as a graduate research assistant at Columbia University (1999–2004). In 2004, he joined the Department of Information, Operations, and Management Sciences at the New York University Stern School of Business as an Assistant Professor. He was promoted to Associate Professor in 2010 and Full Professor in 2016. He holds a courtesy appointment at the Courant Institute of Mathematical Sciences[19] and is an associated faculty member at the NYU Center for Data Science.[20]

Ipeirotis has served as Program Co-Chair for the 13th ACM Conference on Electronic Commerce in 2012,[21] as General Co-Chair of the AAAI Conference on Human Computation and Crowdsourcing (HCOMP) in 2015,[22] and as Technical Program Co-Chair for The Web Conference 2018 (WWW 2018).[23] He has served on the editorial boards of Management Science and IEEE Transactions on Knowledge and Data Engineering, and was a founding co-Editor-in-Chief of the journal Collective Intelligence launched in 2022 as a collaboration between SAGE Publications, the Association for Computing Machinery, and Nesta.[24][25]

His research has been discussed in publications such as The New York Times,[8][26] The Economist,[9] Bloomberg Businessweek,[10] The Wall Street Journal,[27] Financial Times,[28] MIT Technology Review,[29] and TIME.[30][31][32] In 2013, Bloomberg Businessweek profiled him as the "data dude" of business analytics.[33] He has also been profiled in Greek media, including a 2014 interview with Kathimerini discussing Greek higher education and his career.[34]

Academic lineage and doctoral students

Ipeirotis completed his PhD at Columbia University under the supervision of Luis Gravano, himself a student of Hector Garcia-Molina at Stanford. According to the Mathematics Genealogy Project, Ipeirotis has advised seven doctoral students at NYU and Columbia.[35]

His former students include Beibei Li, now a professor at Carnegie Mellon University's Heinz College and recipient of the 2019 INFORMS ISS Sandra A. Slaughter Early Career Award,[36] and Marios Kokkodis, recipient of the 2020 INFORMS ISS Gordon B. Davis Young Scholar Award.[37] Former postdoctoral researcher Djellel Difallah is now Assistant Professor and Program Head at New York University Abu Dhabi and previously served as a Research Scientist at the Wikimedia Foundation.[38]

Research

Ipeirotis's work explores the intersection of computer science and economics, an approach he and collaborators have termed "EconoMining." His research has been published in venues such as Management Science, Information Systems Research, and IEEE Transactions on Knowledge and Data Engineering.[5]

Crowdsourcing and human computation

Ipeirotis has published research on Amazon Mechanical Turk (MTurk). His 2010 paper "Running Experiments on Amazon Mechanical Turk,"[39] co-authored with Gabriele Paolacci and Jesse Chandler, provided methodological guidance for using crowdsourcing platforms in behavioral research.

In 2010, his studies revealing that approximately 40% of tasks posted by new requesters on MTurk involved spam or low-quality content received media coverage.[30][29][32][31] His 2010 demographic analysis of the MTurk workforce provided early data on worker motivations, geographic distribution, and income levels, and has been cited by researchers studying crowdsourcing platforms.[40][41] In 2018 and 2019, media outlets continued to cite Ipeirotis's research on MTurk data quality as concerns about automated responses on the platform grew.[42][26] This line of work led to the development of quality management techniques for crowdsourcing, including the "Get Another Label" framework for improving data quality using multiple noisy labelers, which received the SIGKDD Test of Time Award in 2020.[4]

His research on crowdsourcing best practices also influenced journalism; ProPublica published a "Guide to Mechanical Turk" for investigative reporters that drew on Ipeirotis's research and blog posts, citing his work on data quality through multiple worker verification.[43]

To support this research, Ipeirotis developed "MTurk Tracker," a set of tracking tools for the MTurk platform. The first tool tracked workforce demographics using capture-recapture techniques to estimate the size and composition of the workforce in near real-time. The second tool periodically downloaded all tasks posted on the platform, enabling analysis of the crowdsourcing marketplace's size and activity; Amazon eventually blocked this tracker. The Pew Research Center's 2016 report "Research in the Crowdsourcing Age" drew on data from the task tracker, explicitly crediting "the online tool mturk-tracker, which is run by Dr. Panagiotis G. Ipeirotis."[44][45]

During a 2013–2014 sabbatical at Google, Ipeirotis co-developed "Quizz," a gamified crowdsourcing system for improving the Google Knowledge Graph. The system presented data collection as trivia quizzes targeted by domain expertise, using calibration questions with known answers to assess user reliability in real-time.[12][46]

Data quality and record linkage

Ipeirotis has published research on duplicate record detection and data quality. His 2007 survey "Duplicate Record Detection: A Survey" in IEEE Transactions on Knowledge and Data Engineering, co-authored with Ahmed Elmagarmid and Vassilios Verykios, has been cited in the database research community.[47]

Online reputation and user-generated content

His collaborative work with Anindya Ghose on the economic value of textual content in product reviews quantified the pricing power derived from user-generated content.[48] A related 2011 study demonstrated that the quality of spelling and grammar in product reviews significantly affects perceived helpfulness and product sales.[49] This finding was discussed in Forbes, Harvard Business Review, Slate, and Freakonomics.[50][51][52][53]

Applied research and industry

Early industry work (2009–2014)

Beginning in 2009, Ipeirotis served as an early advisor to Integral Ad Science (originally AdSafe Media), contributing to the development of machine learning systems for detecting inappropriate web content and advertising fraud.[54] In 2011, working with AdSafe engineers, he uncovered a click fraud scheme that used hidden iframes to generate fraudulent ad impressions, which he termed "traffic laundering."[55] The investigation, which estimated the scheme generated hundreds of thousands of dollars monthly, was reported by The Wall Street Journal and MIT Technology Review and led to an FBI referral.[27][55]

In 2011, Ipeirotis co-founded Tagasauris, a media annotation startup where he served as Chief Scientist until 2013.[33] The company combined crowdsourcing with semantic graph technology to tag photo archives. A notable accomplishment was the discovery of approximately two dozen "lost" photographs from the 1973 filming of "American Graffiti" in the Magnum Photos archive; the system identified the photos by using crowdworkers to tag individuals and machine learning to connect them via shared film appearances.[56][57]

He also served as Academic-in-Residence at Upwork (then oDesk) in 2012 and as a Visiting Scientist at Google from 2013 to 2014.[5]

Policy research and World Bank

In 2015, Ipeirotis collaborated with the World Bank on a report titled "The Global Opportunity in Online Outsourcing," which examined the potential of digital labor markets to provide employment pathways in developing nations.[58] Drawing on his empirical research from Mechanical Turk and oDesk, the report estimated the online outsourcing market would grow to $15–25 billion by 2020 and identified barriers preventing workers in the Global South from accessing these jobs, including lack of reliable internet infrastructure and the "reputation cold start" problem. The report has been cited in subsequent policy frameworks by the International Labour Organization and the RAND Corporation.[59]

Detectica and Compass (2015–2022)

In 2015, Ipeirotis co-founded Detectica with Foster Provost and Josh Attenberg, offering AI strategy consulting and machine learning solutions for business applications.[60] The company developed AI-driven compliance monitoring systems for financial institutions. Prior to founding Detectica, the team had designed and built the founding data science architecture for Integral Ad Science.[60]

Detectica was acquired by Compass, Inc. in November 2019.[11] At Compass, the Detectica team developed "Likely to Sell," a predictive analytics system that identifies properties likely to enter the market; the company cited the tool as a significant revenue contributor in earnings calls.[61][62]

Public engagement and pedagogy

Academic integrity debates

In July 2011, Ipeirotis published a blog post titled "Why I will never pursue cheating again," describing his experience using Turnitin software to detect that about 20 percent of the students in his roughly 100-person "Information Technology in Business and Society" course had plagiarized.[63] The post criticized the administrative burden placed on faculty who enforce academic integrity policies and went viral.[64] Ipeirotis temporarily removed the post after a complaint alleged potential violations of the Family Educational Rights and Privacy Act (FERPA) due to included student communications.[64] Business Insider reported that Ipeirotis said his student evaluations declined after the plagiarism cases, costing him part of his annual raise;[65] NYU Stern vice dean Ingo Walter responded that faculty are not penalized for enforcing academic integrity and that student evaluations from such cases are excluded from review.[63] The incident prompted discussion about academic integrity enforcement, faculty incentives, and student privacy.[63][64] The case was subsequently cited in Nature in a 2012 commentary on plagiarism detection in academia.[66]

Security vulnerability discovery

In April 2012, Ipeirotis accidentally discovered a vulnerability in Google Spreadsheets that he termed a "Denial of Money" attack. While running a crowdsourcing experiment that required image classification, he uploaded 25,000 image URLs (hosted on his Amazon S3 bucket) into a Google Spreadsheet. Google's Feedfetcher bot aggressively re-downloaded all images from his S3 bucket every time the spreadsheet was processed, generating massive outgoing bandwidth. Ipeirotis reported receiving an Amazon Web Services bill of $1,177.76—approximately ten times his normal monthly rate.[67]

The incident highlighted a novel attack vector: a malicious actor could create a Google Sheet with thousands of links to a victim's large files, causing Google's servers to repeatedly request the files, resulting in either financial damage or a denial of service. The discovery was covered in technology publications including Wired and The Economist.[68][67][69][70] Amazon subsequently forgave the charges, and Google investigated the behavior.[67]

AI-powered assessment

In December 2025, Ipeirotis developed an AI-driven oral examination system using ElevenLabs voice agents to address concerns about students using generative AI tools to submit assignments while lacking deeper understanding. The system, which cost approximately $0.42 per student to administer, used a voice AI agent to call students and ask personalized questions about their submitted work.[71][72]
