My Research

What it used to be…

I remember back when we were worried about Y2K and I was seeking a job as a newly minted Ph.D. looking to become an assistant professor. Since my training was very frequentist in nature, with emphasis in applying statistical methodlogy to educational and social science research, that was a focus back then. Also, I used to use SAS a lot. I wrote programs for my dissertation in SAS/IML. Yuck!

SAS

MVN

In particular, my dissertation and early publications looked at the power of tests of multivariate normality. I also took some coursework in mathematics education and measurement as a grad student, and I had (and still have) a strong interest in statistics education.

What it is now…

Even back in the 20th century when I was a mere graduate assistant, I was involved in statistical consulting with people from many fields. Although the University of Northern Colorado's applied stats program emphasized educational and social science research, I also worked with people from fields including chemistry education, public health, and wildlife biology. Now that it is the 21st century I've become a mere associate professor that is Bayesian-curious (but hardly full-blown Bayesian) and uses R a lot more than SAS.

R logo Bayes

The majority of my current research is geared towards applied problems that arise in the analysis of biological, ecological, and/or environmental data. This is largely due to becoming involved with many of my colleagues in the Watershed Studies Institute, including biologists, ecologists, chemists, geoscientists, and water scientists. Current interests of mine include the quantitative measurment and analysis of biodiversity and analyzing both left- and right-censored data with GAMLSS (generalized additive models location, scale, and shape). Also, figuring out why Howard Whiteman's pesky tiger salamanders on the top of that mountain in Colorado sometimes decide to go paedomorph and sometimes metamorph.

Here I am as a field statistician at the Mexican Cut in 2011. Cut I think I was sampling with replacement from this container full of salamanders and constructing a sampling distribution of the snout-vent length of the salamanders or something.

I've been involved with the Biomathematics group at Murray State since 2004. We are a group from both the biology and math & stats departments that are interested in research at the interface of those disciplines. We received a NSF grant in 2005 for five years to involve undergraduates in biomathematics research, and subsequently received a three year extension. Check out BioMaPS2 for more information, although the program is now finished.

Thesis Committees

I have been on a few dozen thesis committees at Murray State University, at both the senior honors' and master's degree level, since 2000. Committees that I have been the major advisor for are:

  2. Joshua Lambert, 2010. Better estimates of diversity using zero-inflated distributions. Master's thesis.

Vita…

Email me if you really care. Most publications are above, I've worked at Murray State since 2000 and I was tenured and promoted to associate professor in 2006. I got my M.S. and Ph.D. in applied statistics & research methods from University of Northern Colorado in 1997 & 2000, and my B.S. in mathematics education from University of Wyoming in 1991.
