UI statistics researchers receive federal grants

IOWA CITY, Iowa -- Three University of Iowa researchers in the department of statistics and actuarial science in the College of Liberal Arts recently received federal research funding.

Dale Zimmerman, associate professor and director of graduate studies, and Kate Cowles, assistant professor, are co-principal investigators for a three-year, $200,000 project called, "Combining Environmental Data Using Bayesian Hierarchical Space-Time Models." Funded by the Environmental Protection Agency and the National Science Foundation (NSF), the project considers statistical methods for combining environmental data from multiple sources. The objective of the work is to allow environmental policy-makers to make more well-informed decisions than would be possible using data from only a single source.

Osnat Stramer, assistant professor, has received an 18-month, $75,000 NSF grant for a project titled "Dynamical MCMC methods with applications to continuous time differential equation models." The objectives of the research, which involves computer modeling, are two-fold: to make contributions to statistical inference for stochastic continuous-time models that describe many real world physical systems; and to develop highly efficient computer algorithms for use in simulations.
