Short Bio

Yannis Papakonstantinou is a Professor of Computer Science and Engineering at the University of California, San Diego. His research is in the intersection of data management technologies and the web, where he has published over eighty research articles. He has given multiple tutorials and invited talks, has served on journal editorial boards and has chaired and participated in program committees for many international conferences and workshops. He also teaches for UCSD's upcoming Master of Advanced Studies in Data Science.

Yannis enjoys to commercialize his research and to inform his research accordingly. He was the CEO and Chief Scientist of Enosys Software, which built and commercialized an early Enterprise Information Integration platform for structured and semistructured data. The Enosys Software was OEM'd and sold under the BEA Liquid Data and BEA Aqualogic brand names, eventually acquired in 2003 by BEA Systems. His lab's recent FORWARD platform is now in use by many UCSD and commercial applications. He is involved in data analytics in the pharmaceutical industry and is in the technical advisory board of Brightscope Inc and GraphSQL Inc. He is the inventor of seven patents and has been an expert in IP litigation cases multiple times.

Yannis holds a Diploma of Electrical Engineering from the National Technical University of Athens, MS and Ph.D. in Computer Science from Stanford University (1997) and an NSF CAREER award for his work on data integration.


Current Research
  • FORWARD JSON-era data integration engine and data-driven application platform, supported by NSF 1018961, a Google award and an Informatica award
  • Also in FORWARD, efficiently displaying slow analytics and accomodating mobile displays via an asynchronous SQL/SQL++ server, supported by NSF 1219263
  • Plato: A model-based database for sensor data, enabling declarative statistical queries and performance via compression, supported by NSF 1447943
  • Inconsistency Resolution in Online Databases, supported by NSF 1117527
  • Reengineering Database Systems for Fast SSDs, supported by NSF 1219125
  • The DeLPHI data-driven application platform for Patient Empowerment and Population Health Improvement apps, supported by NSF 1237174

Teaching
  • CSE135, Online Analytics Applications (for senior undergraduate and MS students, current): The course teaches high performance data processing techniques and systems for the support of online analytics dashboards, live views, "Big Data" and "Fast Data" use cases.
  • CSE232A, Principles of Database Systems (for MS and PhD students, current): It primarily covers query processing, query optimization and transaction processing in relational database management systems. The second part covers modern database technologies and advanced topics: Query processing on semistructured data, query processing in virtual databases, incremental view maintenance, column databases, parallel databases.
  • CSE87, Computing and the Universe (priority given to freshmen enrollments, open to other students when space permits, current): Imagine a powerful computer that behaves as a human. Is it conscious? Imagine a computer simulating a universe. Could it be our universe? If so, is God a programmer?! Ranging from Plato, Descartes and classic sci-fi movies to readings on the singularity, we ponder and discuss how computing reshapes humanity's approach to big questions.
