FALL 2017 schedule
Each semester, I teach Genetics (Biology 3330). With varying frequencies, I also teach several introductory courses for Biology majors, including Unity of Life (Biology 1650, lecture and laboratory), Diversity of Life (Biology 1750, laboratory), Fundamentals of Biological Investigation (Biology 2420), and BioQuest (Biology 1020). This semester Dr. Elizabeth Frieders and I are teaching a new course entitled Systematics and Evolutionary Analysis.
In each class I teach, my main goals are to:
- provide students with the knowledge and skills required to think and work as biologists and, more generally, scientists
- foster intellectual curiosity and wonder
I am also committed to:
- contextualizing the diverse topics we study by relating them to evolutionary theory
- encouraging the use of computational and statistical learning methods, which have become important tools for the modern biologist
It is critical that students in the natural sciences perform meaningful research as undergraduates. This experience enriches their understanding of course content and prepares them for employment and postgraduate education. Currently I am engaged in several research areas and encourage motivated students to contact me regarding research opportunities. Because the work in our group requires basic understanding of genetical concepts, I prefer that students have taken Genetics (Biology 3330).
RESEARCH TOPICS: a few of the projects that undergraduates and I are currently pursuing.

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 custom tracks into the UCSC human genome browser. The initial view is centered on MAGI2 (chr. 7); however, all autosomal regions may be viewed.
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.
To simulate the evolution of microsatellite loci themselves under a variety of demographic and mutational conditions, use MARKSIM (Haasl and Payseur 2011), which you can download here.
