Bibliography Tool

Want help maintaining your research bibliography? I created a few R scripts to sort and maintain a collection of research articles. They provide some useful features such as checking if your bibtex file is current, creating a pdf listing of all your references, and creating a .csv table that you can search with grep or view in a spreadsheet that lets you sort easily by year, journal, author, or title. Let me know what you think or if you'd like a new feature added. (id: dsheinz, server: loyola.edu) Currently, it only works if all your articles are in one directory, but searching trumps sorting (at least according to gmail. :)

Teaching

I am currently an assistant professor at Loyola University of Maryland where my chief duty is decreasing the mean age of the statistics faculty. The median, of course, has not changed as much. This semester, I am teaching the following courses: Past courses have included Stat Theory 2, Linear Models, Experimental Design, and a variety of courses designed to introduce statistics to students having backgrounds in natural sciences, humanities, or business.

I use visual aids in a lot of my classes to help students understand important concepts. Here are some examples that I created using R.


Research

My current research involves computational statistics and Bayesian non-parameteric processes. As part of my dissertation research, I developed theory of a graphical version of the famous Dirichlet Process. Graphical in this sense refers to a set of independence relationships among observed variables. I apply this theory to make inference about Bayesian mixture models under conditional independence constraints. By comparing the marginal likelihood of a set of data under various graphical models, I determine the relationship between variables from a mixture of distributions. I have written code for these two applications, which is available here. In addition to working with the graphical Dirichlet Process, I am interested in expanding the theory to other extensions and applications, including the Hierarchical Dirichlet Process of Teh, et al., and Pitman-Yor Processes. Graphical versions of the Beta Process are also particularly exciting.

It may be a cliché, but I am generally eager to learn about almost any topic. I have worked at various times as a teaching assistant in a chemistry lab, a research assistant in a cognitive psychology lab, and as a proof-reader and solutions-writer for a topology textbook. I hope to become more involved in interdisciplinary research in the near future, especially regarding cognition and linguistics.
