Julia Stoyanovich

I am a Visiting Scholar at the University of Pensylvania, where I work with Professor Susan Davidson and her group.
From 11/2009 to 10/2011 I was a Postdoctoral Researcher and a Computing Innovations Fellow with this group.

From 09/2004 to 10/2009 I was a PhD student in the Department of Computer Science at Columbia University, where I worked with Professor Ken Ross.

I received my B.S. in Computer Science and Mathematics and Statistics from UMass Amherst in 1998.

I am originally from Moscow, Russia and Belgrade, Serbia.
While in Belgrade, I attended the Belgrade Mathematical High School.

My CV is available here.

I am married to Oleg Sarkissov, a foodie, talented art director and photographer.

research
 
My research is motivated by the data management needs of life sciences applications and of social information processing, two areas where the abundance and the richness of data, and the need to rapidly transfer data into information and into knowledge, pose exciting opportunities and interesting challenges. My dissertation "Search and Ranking in Semantically Rich Applicationsā" considers how semantic and social context may be used to allow for novel kinds of interaction between the user and the information in a variety of digital environments, ranging from social content sites, to digital libraries, to the World Wide Web. In a recent line of work I have been exploring how ranking in large structured datasets can be used to enable a richer data exploration experience. I have also been actively involved in managing data provenance in scientific and social applications, and in the related privacy and security considerations.
 
news
 
The proposal "Identifying Ranked Agreement Among Raters", by Susan Davidson and me, was funded by Google, through the Research Awards program.
Topics explorer functionality, developed by Paramveer Dhillon, Brian Lyons, Susan Davidson and myself, was released by myExperiment.org on September 7, 2011. Topics explorer uses tags and tag co-occurrence to organize the myExperiment workflow repository into categories, and is based on the latent Dirichlet allocation (LDA) topic model.
