Research (Group's Homepage)
My work has charted new directions or bet on emerging directions that
I believe would become fundamental for data management. Current directions:
knowledge bases/graphs (2004-2012),
schema/ontology matching (2000-2010).
In between, from 2010-2014 I
some time in Silicon Valley, putting my work in these directions
to use, and learning a ton about doing things "in the wild".
- Data cleaning & integration:
I build end-to-end data integration systems as parts of the Python ecosystem of open-source data tools. I also leverage these systems to build cloud/crowd data integration services for lay users.
science: This direction is increasingly critical to the data
management community, yet no clear agenda exists today. I'm working
on an agenda that integrates research, system
building, education, and outreach. This agenda currently focuses
on data quality and builds on the above
work in data cleaning/integration.

- Selected recent service for the data management community:
- member, SIGMOD Advisory Board,
- member, ICDE 10-Year Most Influential Paper Award Committee,
- associate editor, VLDB-16,
- co-chair, industrial program, VLDB-15,

- I spent 3 years (2011-2014) setting up a
professional MS program and a
program in CS at UW-Madison (with help from Karu Sankaralingam,
Jeff Naughton, and Suman Banerjee). These programs have been highly
successful, enrolling hundreds of students.
- I've participated in or led several important strategic
initiatives for CS at UW-Madison. These include growth to 50
(tenure-track faculty), a re-organization of the department's
governance structure, and data science initiatives. I serve as an
associate chair since 2017. I've also worked on several strategic
initiatives for UW-Madison, including serving on the steering
committees of several data science centers and initiatives, and
serving on the 2017-2018 campus
force for growth strategies for computing at UW-Madison.
