Research Interests: I come from a soil ecology background and am new to the cottonwood ecology research group. My role is to look for ways to incorporate structural equation modeling (SEM) into the groups past, present and future research. The way I think about data analysis and about how to do science in general has changed alot in the last few years as I have added SEM to my toolbox. SEM is a fascinating causal inference method that has it's roots in Sewall Wright's path analysis, and was later merged with Pearson's factor analysis and Fisher's maximum likelihood theory, and is constantly evolving today. After a long history in the social sciences, SEM is just starting to find its way back to it's biological roots. I think it has great potential in community genetics for two main reasons: 1) it allows strong causal inferences to be drawn from observation, non-experimental data, and 2) it allows the analysis of Markovian chains of events in either experiments or observational data. NO standard "off-the-shelf" statistical technique shares these properties. Another advantage is that it allows a flexible combination of linear, polynomial, or logistic relationships.
