Research InterestsDr. Welty's research interests include formulation of statistical models for outcomes correlated over time and space and the associated challenges in estimating these models. Her recent work on the National Morbidity Mortality and Air Pollution Study (NMMAPS) has focused on formulating generalized linear models to adequately capture the short term health effects of air pollution and weather while controlling for other time-varying factors. In particular, she has been investigating Bayesian methods for distributed lag models. She has also worked on formulating covariance models for random fields and estimating likelihoods for very large data sets, using algae levels in Lake Michigan collected as part of the EEGLE project. |
