Lab Members


Karine Abazajian (Class of 2022 at Tulane)

Kara is an ecology and evolutionary biology major from Houston, Texas. Her interests include, but are not limited to insect biology and marine and freshwater biology. She has participated in community-based projects on salamander ecology.

In the Hedrick lab, she is examining the relationship between magnitudes of fluctuating asymmetry and urbanization in Virginia opossums. She is doing this by quantifying asymmetry in opossum skulls and mandibles with two-dimensional geometric morphometrics.

Marc Merriman, Jr. (Class of 2022 at Xavier)

Marc is Biology Major with a double minor in Chemistry and Business Administration at Xavier University of Louisiana. Throughout his academic career, Marc has participated in various internships where he has shadowed an array of specialties, including orthopedic medicine. He is interested in researching the relationship between human anatomy/ physiology and ethnic differences. As Marc pursues a career in medicine, he hopes to apply the knowledge and intellectual capital gained from this research to aid in advancing orthopedic and/or cardiac medicine.

In the Hedrick lab, he is working with carnivoran mammal CT scan data to determine the relationship between ankle morphology and locomotor mode. 


Alexandra Magee (Class of 2024 at Xavier)

Alexandra is a freshman at Xavier University in Louisiana. She is a  biochemistry major from Tylertown, Mississippi. Currently, her interests include osteology, microbiology, and thermochemistry. She has participated in internships and advanced science projects involving maxillo-facial anatomy and surgery.


In the Hedrick lab, she is assessing the relationship between limb symmetry and locomotor ability in green anoles. Specifically, she is using CT data of green anole forelimbs and hindlimbs for individuals that have known ecological data from previous experiments (e.g., maximum sprinting speed, clinging ability) to determine whether anoles with more symmetric limbs are able to locomote more effectively than anoles with more asymmetric limbs.


Jazmine Aguilar (Class of 2023 at LSU)

Jazmine graduated in the Spring of 2020 from the University of Illinois at Urbana Champaign with a BS in Animal Science and a minor in Psychology. She is currently a first year grad student in the Biomedical Sciences MS program. Her goal after graduating is to continue to vet school and pursue a career in veterinary medicine. Specifically, she aims to help transcend the current standards of veterinary care for underserved communities by providing exemplary animal care.


In the Hedrick lab, Jazmine is using CT scan data to collect cross sectional parameters for humeri and femora of a variety of small mammal species (e.g., bats, rodents, shrews, moles). These data will be used in collaboration with Dr. David Boerma (Cornell) to examine the relationship between bat roosting ecology and bony parameters with the goal of understanding how landing on hard cave walls versus compliant trees impacts the evolution of bat limb internal geometry. 

Lab Alumni

Farid Abou-Issa (Class of 2025 at LSU)

Farid is a first year medical student pursing an MD at LSU Health Science Center in New Orleans. There, he hopes to learn as much as possible about radiology, internal medicine, ambulatory medicine, and especially physiology. He acquired a Bachelor's in Biology from the University of Louisiana at Lafayette where he learned about everything from humans to terrestrial plants and algae. His interests outside of medicine include computer science, gaming, and anything else involving a computer. 

In the Hedrick lab, he is working with CT scan data of a variety of mammal groups to assess how different mammal groups (rodents, shrews, moles, and hedgehogs) have converged in limb shape across different locomotor ecologies.
