Bob Metcalfe

Bob Metcalfe just entered his 6th career: COMPUTATIONAL ENGINEER. He's been appointed Research Affiliate in the Computer Science and Artificial Intelligence Lab (CSAIL) at MIT, his alma mater. For 11 years Bob served as Professor of Innovation at the Cockrell School of Engineering, Professor of Entrepreneurship at the McCombs School of Business, and Murchison Fellow of Free Enterprise at The University of Texas at Austin. Bob retired from UTAustin as Emeritus Professor of Electrical and Computer Engineering. "My work here, on the Texas/Austin/UTAustin startup ecosystem, is done." Bob was an Internet pioneer beginning in 1970 at MIT, Harvard, Xerox Palo Alto Research Center (Parc), Stanford, and 3Com. He invented Ethernet at Parc on May 22, 1973. Today Ethernet is the Internet ' s standard plumbing, each year adding billions of ports, if we let Bob count Wireless Ethernet (Wi-Fi). Bob remains a champion of Ethernet and connectivity in general, according to Metcalfe's Law (V~N^2). The Internet turned 50 in 2019, just in time for COVID-19. The most important new fact about the human condition is that, and it ' s mostly good news, we are now suddenly connected. Among many other honors, Bob has won the Bell, Hopper, Japan C&C, Marconi, McCluskey, Shannon, and Stibitz Prizes. He has been inducted into the Internet, Consumer Electronics, and Computer History Museum Halls of Fame. He is Emeritus Life Trustee of MIT. Bob received the Institute of Electrical and Electronics Engineers (IEEE) Medal of Honor in 1996 and the National Medal of Technology in 2005 for leadership in the invention, standardization, and commercialization of Ethernet. Bob founded Internet startup 3Com Corporation in Silicon Valley on June 4, 1979. 3Com went public on March 21, 1984. Bob &quot retired” from 3Com in 1990. In 1999, 3Com revenue was $5.7B, and its market capitalization peaked momentarily at an inflation-adjusted $52 billion, of which Bob didn’t even get half. 3Com was acquired by HP Enterprise in 2010. During the 1990s, Bob was CEO/Publisher/Pundit at IDG/InfoWorld Magazine. His Internet column, FROM THE ETHER, was read weekly by a million? information technologists among IDG ' s 90 countries. In his column he was famously wrong in predicting the Internet would suffer a gigalapse in 1996. Read all about this prediction in Bob ' s book, INTERNET COLLAPSES, still available on Amazon.com. During the 2000s, Bob was a limited, venture, general, and now emeritus Polaris Partner in Boston.

Barbara Poblete

Dr. Barbara Poblete is an Associate Professor at the Computer Science Departmentof the University of Chile and an Amazon Visiting Academic at Alexa Shopping Research. She is Co-PI at IMFD and CENIA in Chile, the first large government funded research centers dedicated exclusively to Data and to AI, respectively. Formerly, she was at Yahoo! Labs. Her main research areas are Social Network Analysis, Web Data Mining and Information Retrieval. She co-authored a series of innovative works on the topic of online misinformation, including the article " Information Credibility on Twitter " (2011) awarded the 2021 IW3C2 Seoul Test of Time Award. This widely cited work, was pioneer in studying so-called &quot fake-news &quot and has been featured in SciAM, WSJ, Slate, The Huffington Post, BBC News and NPR, among others. Her research has also focused on the problem of multilingual and language agnostic approaches, specifically for online hate-speech and crisis informatics. In this regard, she has led initiatives such as Twicall.cl, a social-based real-time earthquake detection system, used by the National Seismology Center and other emergency response agencies in Chile. She has co-authored over 80 peer-reviewed articles, including top-tier venues such as TWC, SIGIR, EMNLP and ISWC. Other distinctions include the Google Latin American Research Award and being nominated among Chile ' s " 100 Leaders under 35 " . Currently, she is among the top most cited women computer scientists in Latin America. She is Program Committee co-Chair for SIGIR 2023, and recent activities comprise Track co-Chair for TWC, Doctoral Consortium and DEI co-chair for SIGIR, Program Committee Chair for SPIRE, AMW, LA-WEB, and Editorial Board member for Foundations & Trends in IR, Associate Editor for TWeb. She is also co-founder of ChileWiC, local ACM-W chapter for women in Computer Science.

David Rand

David Rand is the Erwin H. Schell Professor and Professor of Management Science and Brain and Cognitive Sciences at MIT. David’s research combines survey experiments and social media field experiments to understand human decision-making online. His work focuses on illuminating why people believe and share misinformation and ·&qu o tfake news”; understanding political psychology and polarization; and promoting human cooperation. He has published over 170 articles in peer-reviewed journals such Nature, Science, PNAS, the American Economic Review, Psychological Science, Management Science, New England Journal of Medicine, and the American Journal of Political Science, and his work has received widespread media attention. David regularly advises technology companies such as Google, Facebook, and Twitter in their efforts to combat misinformation, and has provided testimony about misinformation to the US and UK governments. He has also written for popular press outlets including the New York Times, Wired, and New Scientist. He was named to Wired magazine’s Smart List 2012 of " 50 people who will change the world,” chosen as a 2012 Pop!Tech Science Fellow, awarded the 2015 Arthur Greer Memorial Prize for Outstanding Scholarly Research, chosen as fact-checking researcher of the year in 2017 by the Poyner Institute’s International Fact-Checking Network, awarded the 2020 FABBS Early Career Impact Award from the Society for Judgment and Decision Making, and selected as a 2021 Best 40-Under-40 Business School Professor by Poets & Quants. Papers he has coauthored have been awarded Best Paper of the Year in Experimental Economics, Social Cognition, and Political Methodology.

Payal Arora

Payal Arora was born in India but was shipped off to San Francisco in her teens after causing much trouble with her Marxist artistic experiments in Kerala. Instead of starting her own Hare Krishna club in California, she waitressed and did street art, a perfect combination to remind her that poverty wasn’t that sexy after all. She sold her soul soon after and became an art dealer, selling expensive art with the right mix of cheap wine and cheese, but thankfully this was interrupted by her love affair with New York where she stumbled into research. In came her passion for global culture, technology and communication which she pursued by accumulating some good old ivy league degrees from Harvard and Columbia University so she could say stuff like ‘I went to school in Boston.’ Since then, she has been studying digital usage among the global poor and consulting for numerous private and public sector institutions like GE, KPMG, UNESCO, and Dutch Brewers. To prove she isn’t just traveling all the time and eating great food, she has to publish articles and books including her latest ‘The Next Billion Users” book with Harvard Press. She is currently a Professor at Erasmus University Rotterdam and calls Amsterdam her home.

Zachary Elkins

Professor Elkins’ research focuses on issues of democracy, institutional reform, research methods, and national identity, with an emphasis on cases in Latin America. He is currently completing a book manuscript, Steal this Constitution: The Drift and Mastery of Constitutional Design, which examines the design and diffusion of democratic institutions. Much of his research is on the origins and consequences of national constitutions. With Tom Ginsburg (University of Chicago), Professor Elkins co-directs both the Comparative Constitutions Project , a NSF-funded initiative to understand the causes and consequences of constitutional choices, and the website Constitute , which provides resources and analysis for constitutional drafters in new democracies. Elkins earned his B.A. from Yale University, an M.A. from the University of Texas at Austin, and his Ph.D. from the University of California, Berkeley.
