Tonia Schwartz, PhD
Associate Professor
Principal Investigator
Dr. Tonia Schwartz started her research career as an undergraduate at Iowa State University working with Drs. Bonnie Bowen and Carol Vleck using genetic markers to study populations of jays and to determine the sex of penguins. While doing a Masters of Science at University of South Florida with Dr. Steven Karl, she obtained a foundation in Population and Conservation Genetics while deciphering the population structure of gopher tortoises. Before starting her PhD she spent four years in Australia conducting research on diverse topics including fisheries management, speciation and hybridization, molecular evolution of metabolic proteins, and sexual selection. As a genetics PhD student at Iowa State University she was an NSF-IGERT fellow in Computational Molecular Biology, a NSF-GK12 fellow, and was advised by Drs. Anne Bronikowski and Jo Anne Powell-Coffman for her dissertation identifying how molecular stress response networks can diverge between natural populations of garter snakes that are at either end of the pace-of-life continuum. She was awarded a James S. McDonnell post-doctoral fellow in complexity science, which she took to University of Alabama at Birmingham to work in the Office of Energetics with Drs. David Allison and Julia Gohlke. During this time she studied transgenerational affects of stress on metabolism, reproduction, and longevity, and the evolution of molecular networks. In 2015 she was hired as an Assistant Professor at Auburn, and thus the Schwartz lab of Functional and Ecological Genomics was established.
Dr. Danielle Rivera
Postdoctoral Fellow
Dr. Danielle Rivera comes to the Schwartz Lab fresh off a Postdoc with Drs. Rayna Bell (California Academy of Sciences), Nathan Hostetter and Jaime Collazo (USGS/North Carolina State University) focused on sequencing Caribbean skink genomes and aiding US Fish & Wildlife in their Species Status Assessments of skink species (genus Spondylurus) within the Caribbean US. She got her PhD at the University of Texas at Arlington with Dr. Matt Fujita studying phylogenomics of Neotropical herps, and her Masters at the City College of New York with Dr. Ana Carnaval studying Brazilian skinks. She is joining the Schwartz lab on the SMAL Project, working on the evolution of molecular networks among lizards and snakes in the Channel Islands.
Fun Fact: Danielle loves organizing, spending time with her bearded Dragon (Stefan), and casually birding.
Dasia Simpson
PhD Candidate
Native to Atlanta, Georgia. Dasia's career passion is to communicate science to young audiences. Her current project focuses on the stress response of both vertebrate and invertebrate organisms. Specifically, she studies the stress repsonse at the transcriptomic level in Sceloporus undulatus, the eastern fence lizard, when exposed to heat and fire ant envenomation. She is also intrigued by Daphnia pulicaria, a microscopic water crustacean, and the selective pressures that enable populations to survive in toxic algae.
Fun (Weird) fact: I love seafood but I think fishes, really all organisms bigger than a daphnid, that live in water are creepy.
Taylor McKibben

Additionally, I am working on a collaborative project with Dr. Jeff Goessling from Eckerd College to study gopher tortoises and the effects of head starting on molecular stress resistance and life history traits in gopher tortoises.
Fun Fact: I collect guitar picks.
Sagar (Ocean) Bhowmik
PHD STUDENT
I am a PhD Student from the mystical landscapes of Bangladesh. I'm on an exhilarating quest to decode the enigmas of biological sciences. Currently, I'm immersed in two captivating projects: the "Damage Fitness Project" and the intriguing "Dwarf Reptile Project." Specifically, I'm currently focused on assessing DNA damage and intricately crafting aptamers for precise protein quantification. Moreover, I find joy in the world of molecular dynamics and simulations, where I play with atoms and molecules to decode life's intricate dance.
Fun Facts: Beyond the lab's walls, I capture fleeting moments through the lens of my camera, finding art in science and life. And when time permits, I'm an explorer at heart, venturing into uncharted territories.
Join me in this odyssey of curiosity as we journey together to decipher the universe's most cryptic puzzles.

Stephen Tansie
PHD STUDENT
I join the lab from Ghana. I am using whole genome sequencing data, I am currently conducting a metagenomic analysis to identify and classify the microbes in the blood of Pituophis catenifer captured from island and mainland populations. I also intend to explore the evolution of microbial (bacterial) virulence between these two populations.
Alexis Lindsey
MS STUDENT
I’m a first year masters student from Huntsville, Alabama and I’m passionate about southeastern herpetofauna. My current project focuses on exploring the molecular mechanisms behind dwarfism exhibited in a number of reptile species on the Channel Islands. I also work with the Memphis Zoo’s Louisiana Pinesnake captive breeding program.
Fun Fact: my favorite animal is a mud snake!
Ali Amer
PHD STUDENT
Originally from Pakistan, I graduated with a BS in Biochemistry in 2023 from Ohio Wesleyan University. Broadly, my interests include understanding the interactions between physiological and molecular systems and how they modulate animal behavior. Currently, I am working on the Damage-Fitness project investigating the molecular measures of cellular damage, protection and repair.
Fun Fact: In his spare time, Ali enjoys going out on hikes and recently climbing.
Brynleigh Payne
PHD STUDENT
Brynleigh is from Alabaster, Alabama. She graduated from Auburn in Genetics while conducting molecular sexing within the Aging Anoles project. She is using Nanopore sequencing to quantify sex chromosome telomeres in anoles and now in zebra finches to understand sex-specific effects of stress on DNA damage.
Fun Fact: Brynleigh studied abroad in Costa Rica for a course focused on biodiversity, conservation, and sustainability.

This animal room contains space and racks for an 400 individual lizard cages. This room is equipped with work counter space and a sink.
OUTDOOR EXCLOSURES
Our outdoor facility is referred to as “The Aviary” (historical reasons) and is an outdoor facility for set up of semi-natural environments. It is at a locked and secure location about 1 mile from the Department of Biological Sciences (DBS) on Auburn University’s Main Campus. The Aviary is a Department of Biological Sciences facility used by many organismal biologists in the department. This facility has been completely renovated (financially supported by DBS and the College of Sciences and Mathematics) with adjustable cages over a 32 x 82 ft area that can be arranged into replicate enclosures for short term and long term experiments.
