IBM researcher Phokion Kolaitis was recently elected Fellow of the American Association for the Advancements of Science (AAAS) - an esteemed honor in which the organization's council elects those whose "efforts on behalf of the advancement of science or its applications are scientifically or socially distinguished." Dr. Kolaitis, recognized for his "distinguished contributions to logic in computer science and to the principles of database systems", always had a knack for math and logic. I spent some time with him to talk about this accomplishment, fueled mostly by, as he puts, "The drive for knowledge. I always had this curiosity and passion for advancing the frontier of knowledge."
And passion was a common theme in the discussion of Phokion's academic and career achievements. By high school, the Greece native had already decided he wanted to pursue mathematics. Once he entered University of Athens as an undergraduate, he felt science was what interested him, but that mathematics was the underlying basis for all things scientific. As he excelled in the university, he found himself focusing on the foundations of mathematics and, in particular, on mathematical logic. After completing his Ph.D. in Mathematics from UCLA, his interests evolved to applications of logic to computer science with particular emphasis on the connections between logic and databases. He became a professor of computer science at UC Santa Cruz and later on spent four years at Almaden as a research staff member and senior manager of the department of computer science principles and methodologies, also known as the "theory group."
"One of the reasons I wanted to come to IBM from academia was because I wanted to work on the foundations of information integration," explained Phokion, "in an area called schema mappings and data exchange." This area of study focuses on trying to develop methods and tools for restructuring data organized under one format into data organized into another. "It's a very old but recurrent problem in databases. With other colleagues at Almaden, we developed a framework for studying this problem that, in turn, facilitated the development of tools to ease the challenges." This work was recognized by IBM Research as an outstanding accomplishment, while at the same time some of the papers published on this topic have received hundreds of citations.
Outside of his career, Phokion has an uncommon hobby: collecting fountain pens. His collection features about 250 pens, mostly vintage pens from the United States, Germany, and the UK, but also modern pens from France, Italy, and Japan. His favorite and most precious pen is his father's - a Parker '51 with a rare broad nib.
Phokion keeps a close relationship with his children, both of whom are pursuing medical careers - his daughter Irini is currently a first-year pediatric resident at the Children's Memorial Hospital in Chicago after earning her MD at Georgetown University and his son Nicholas is a third year medical student at UC San Diego. Phokion is a fan of classical music and enjoys Greek poetry, citing his favorite poet as George Seferis, the winner of the Nobel 1963 Nobel Prize for Literature. Seferis captivated Phokion - as he says "Seferis' speech at the Nobel Banquet encapsulates my own feelings about the Greek language, poetry and the human condition."
Phokion will be presented the AAAS Fellow award during a recognition dinner in Washington, D.C. on February 19, 2011.

Great minds gather at Berkeley's Watson viewing event
The following post was written by guest contributor Steve Demello, CITRIS' Healthcare Director at UC Berkeley.
Some 300 enthusiastic students, faculty and researchers came together at Sutardja Dai Hall, the headquarters of the Center for Information Technology Research in the Interest of Society (CITRIS) at the University of California Berkeley, to watch and discuss the final episode of the Jeopardy! Challenge featuring IBM’s Watson platform. The event, distributed throughout the building and on the Internet with streaming video, included presentations and commentary about the event itself, Watson, and the future it portends for Natural Language Processing (NLP).
The event began with a welcome from Professor Paul Wright, Director of CITRIS, who underscored the importance of the Challenge and applauded IBM for its achievement. Jean Paul Jacob, CITRIS Senior Advisor and a career IBM executive, entertained the audience with a “pregame” presentation on the structure of the Jeopardy! game, the evolution and structure of Watson, and a summary of the first two days of competition.
Dr. Jacob was joined onstage by two distinguished commentators – Professor Shankar Sastry, Dean of the UC Berkeley College of Engineering, and Dr. Horst Simon, Deputy Director of the Lawrence Berkeley National Laboratory – on a set mimicking the game show itself, including Berkeley’s own version of Watson, dubbed “Chaplin”. Drs. Sastry and Simon commented before, at breaks during, and after the broadcast about the game, the technology, and future implications. They were joined in discussion by an engaged audience that included Professor David Patterson of the UC Berkeley Computer Science department and Michael Stewart, a former Jeopardy! champion.
The event concluded with reflections from Drs. Sastry and Simon, and discussion with the audience. Both commentators agreed that Watson represents a significant step forward in leveraging NLP, and that the capabilities demonstrated on Jeopardy! will be applied to a variety of areas, such as customer service. Both praised the “human ingenuity” at the heart of the technology, and Dr. Simon urged the group to consider this as an evolutionary step in a process that began in the 1940’s and 1950’s with early breakthroughs in computation. The commentators and audience both expressed their hope that IBM will share as much as possible with the broader research community, so that it can learn from what has been accomplished and to drive this exciting area of research forward.
Perhaps Professor Sastry best summed up the evening when he said that, as a technologist, “this was more exciting than the Super Bowl … with better ads.”

Man vs Machine? Almaden friends and family gather for Watson's championship showdown
Watson wins!!!
Watson had the whole world engaged during its 3-day match against Jeopardy's best two contestants, Brad Rutter and Ken Jennings. The Almaden lab was host to over 200 IBMers and their friends and families on the night of the finale, and witnessed Watson battle its way to the winning spot, earning $1 million dollars for charity!
Here are some clips of the buzz before the game:
