Undergraduate research

I believe it is important to provide students in the natural sciences with opportunity to perform meaningful research. This experience enriches their understanding of course content and prepares them for employment and postgraduate education. Currently I am engaged in several research areas. In most cases, I prefer that students have taken Biology 3330 (Genetics) before working with me because the work of our group requires a basic understanding of genetical concepts. However, I encourage all students interested in biological research in one of the RESEARCH TOPICS we're pursuing to contact me.


software and datasets


This software simulates the spread of Japanese hops in the riparian zones of the Driftless area. The user controls ecological and life history parameter values. Each year positional and genetic information of living plants are output. An R script is also provided to visualize results and perform population genetic analyses. The compressed files also provide a pdf with documentation.

To download source code, go to the GitHub repository and select "Download ZIP". Basic instructions are in the README file, while more detailed instructions are found in the invasion.pdf documentation file.


This software simulates 1Mb chromosomal segments with a selected SNP or microsatellite at it center (500kb). New mutation, recombination, and reproduction are all accounted for. We wrote this software to produce the simulated datasets detailed in Haasl, Johnson, and Payseur (2014). It requires the use of Hudson's ms program, which is bundled with our source code. Please e-mail for source code.

Datasets for Haasl, Johnson, and Payseur (2014)

Full autosomal scan of 85 individuals of Northwestern European ancestry (population CEU) using the ksk2(20) and ksk2(1) statistics detailed in Haasl, Johnson, and Payseur (2014). 

The following links will load the custom tracks into the UCSC human genome browser and open to all of chromosome 19 (takes a bit to load). However, any part of an autosome can be viewed by entering the desired region in the search box of the genome browser.
