Research Experiences


Keogh Lab - Phylogenomics of Australian reptiles

Australian National University | Canberra, Australia

As a postdoc with Scott Keogh, I am involved with inferring phylogenomic trees for several groups of Australian reptiles as part of the Australian Amphibian and Reptile Genome (AusARG) project.

Keogh Lab - Macroevolution of blindsnakes in Australia

Australian National University | Canberra, Australia

My PhD research consisted of two major parts. This first part involved extracting DNA from tissues deposited in museums across Australia, sequencing the DNA, and infferring a phylogeny for the Australian blindsnake genus Anilios. In the second part I used the phylogeny to test hypotheses about biogeographical history of the group, diversification dynamics, and how traits evolved in this continental radiation of ecologically conserved group.

Warner Lab - anoles

Auburn University | Auburn, AL, USA

My masters thesis research sought to find out if nesting behaviour by mother lizards can shield her eggs from non-ideal conditions. The fieldwork for this project was really fun because I got to walk around suburban Miami and look for anole eggs. We got some odd looks from passerby every now and again but every time was a great opportunity to tell a story about mother lizards and her eggs!

This project challenged me to organize a 2.5 month field work in Miami, not give in to mosquitoes, and to consider different ways to analyse data. I learned a lot about where anoles lay their eggs. Other than my thesis, I also assist in other on-going projects in the Warner Lab and act as a resident IT trouble shooter for my lab mates. Co-authors: Nathaniel Pavlik, Josh Hall, and Dan Warner

Warner Lab - turtles and anoles

University of Alabama-Birmingham | Birmingham, AL, USA

I was funded by the Gonzaga Off-Campus Research Experience grant to work with Dr. Dan Warner (who was at the University of Alabama-Birmingham at the time). For the first part of the summer, I collected nesting data on Western painted turtles (Chrysemys picta) in Round Lake State Park nearby Sandpoint, Idaho, as part of a long-term study on the geographic variation of temperature-dependent sex determination. For a month we camped in this lovely state park and went “turtling.” It was a fabulous time with camp foods every night.

The second part of the summer was at UAB. There, I conducted an experiment to test the effect of incubation conditions on survival and hatchling phenotypes of anole populations from urban and forested sites. This was the first time I learned to handle lizards and was responsible for caring for them. Prior to this experience, I was adverse to lizards, thanks to Tim Mitchell for showing me the ropes. After the summer, I analysed data and prepared manuscript that led to my first publication (Tiatragul et al. 2017).


Swanson Lab - fiddler crabs

Undergraduate Research Assistant

Gonzaga University, Department of Biology | Spokane, WA, USA

My first research experience introduced me to the beautiful and combative world of fiddler crabs. Males use their major claws to fight each other and attract females. This project took me back to my native Thailand where I collected male fiddler crabs (Uca spp.) claws from the field and brought them back to analyse their morphology digitally using imageJ.

This was also my first time working with a decent size data set (n=200+) and learning R. By my senior year, I analysed some data and spent too much time trying to get this mediocre graph shown on the right! I like to think I have come a long way with R since.
