About me


I am a statistician and data scientist whose methodological research focuses on the development of high-dimensional multivariate spatiotemporal models, on variable and model selection, and on graphical models. My work has been published in more than 30 journals such as Journal of the American Statistical Association, Annals of Statistics, Annals of Applied Statistics, Journal of Multivariate Analysis, Journal of Computational and Graphical Statistics, Bernoulli, Bayesian Analysis, Proceedings of the National Academy of Sciences, International Journal of Epidemiology and AIDS. My applied work has a broad range with key foci related to public health, demography, computational social science, modeling of complex dynamical phenomena using big data, and pathway determination and disease risk assessment from network analysis of large scale genomics data. My most recent interests are related to human mobility and migration based on geolocated temporal data recorded by wearable sensors embedded in smartphones, and on unsolicited geotagged social media data. My research has been funded by the National Science Foundation and by the National Institutes of Health.

I serve as Editor for Bayesian Analysis, and as Associate Editor for the Annals of Applied Statistics, and Metrika. I am Director of the UW Master of Science in Data Science program, and Chair of the Graduate School's Interdisciplinary Data Science Group. In addition, I serve as Associate Director and Graduate Chair, Center for Statistics and the Social Sciences. I am involved in the Center for Studies in Demography and Ecology, the eScience Institute, and in Department of Biobehavioral Nursing and Health Informatics.

I joined the University of Washington as an Assistant Professor in September 2006. Between 2001 and 2006 I worked at Duke University as a postdoctoral fellow at the National Institute of Statistical Sciences and the Statistical and Applied Mathematical Sciences Institute, then as a Research Assistant Professor affiliated with the Department of Statistical Science and the Department of Molecular Genetics and Microbiology. As of September 2012, I was promoted to Associate Professor with tenure.

I received a BS in Mathematics and a MS in Computer Science from the University of Bucharest in 1995 and 1996, respectively. In 2002 I obtained my PhD in Statistics from the Department of Statistics, Carnegie Mellon University.
