I am an assistant professor at the School of Electrical Engineering & Computer Science of the Oregon State University. I did my PhD in the Department of Computer Science at the University of Illinois at Urbana-Champaign. I lead the Structured Data Science Lab. We create systems with principled foundations that enable users to explore and analyze large data sets easily and effectively and help them unlock the value of data. We tackle problems in the areas of data management, data analytics, and Big Data.


  • Check our recent paper on representation independent data analytics. Because the results of current data mining and machine learning algorithms depend how their input databases are represented, developers have to spend great deal of time and resources to transform the databases to their desired representations for these algorithms. The paper argues for representation independent methods for data analytics.
  • Congratulations to Amirhossein for being named a Siebel Scholar !
  • Thanks to NSF for supporting our research through award "III-Generalizable Similarity and Proximity Metrics For Data Exploration". The grant will fund our work on representation independent graph analytics.
  • We will present three papers in SIGMOD/PODS 2014: Yodsawalai presents a paper on graph analytics in GRADES workshop, Jose presents our work on scalable relational learning in BUDA workshop, and Arash presents a paper on automatic conceptual design in SIGMOD. Come by and join us!
  • Congratulations to Jose for winning a SIGMOD travel grant!
  • Congratulations to Jose for winning a Rickert Scholarship!
