Lab Members


Andrew Orkney (Postdoctoral Research Scholar)

Andrew is an early career researcher with wide-ranging interests across the biological sciences, reflected in a publication record that spans satellite monitoring of Arctic plankton blooms to the inference of ecological attributes in Dinosaurs from fossil bone histology. His main field of interest is ecomorphological adaptation, evolvability and anatomical organisation of the vertebrate skeleton. 

His responsibilities, working in the Hedrick Lab, include the production of 3-D skeletal models from CT-scan data and downstream geometric morphometric analyses, taking advantage of sophisticated mathematical methods. This work will increase understanding of the intersection between aerial and dietary ecology and limb skeleton morphology across bats, in the context of large inter-specific variation in body mass. This will help illuminate the evolutionary solutions employed by bats to transcend mechanical constraints and rule the night!

William Hooker (Class of 2024 at Cornell University)

Will is an Earth and Atmospheric Sciences (EAS) major with a concentration in Geological Science and a minor in Biology. His interests include vertebrate paleontology, fossil collecting, and paleoart. To share his enthusiasm about Earth science, Will founded the Pangea Club at Cornell. Will's experience ranges from exhibition design at the American Museum of Natural History to running high-temperature geochemical experiments in the EAS Department. 


In the Hedrick Lab, Will is examining cranial data using three-dimensional geometric morphometrics to assess the degree of asymmetry in the mammal-like reptile Diictodon (Synapsida, Therapsida) and explore how taphonomic processes alter interpretation of the fossil record.

Tram Huynh (Class of 2024 at Cornell University)

Tram is a Junior studying Biology and is interested in exploring evolution through statistical analysis by identifying patterns and visualizations of data. At Cornell, she is an active mentor in YOURS and CCRI, and is an avid ping pong and tennis player. Her goals are to attend optometry school post-undergrad as well as try all the foods in the Ithaca area.

Tram is working in the Hedrick Lab to examine how bat forelimb bone asymmetry is associated with different landing styles. She is working with microCT data of bat skeletons and landmarking software.

Lauren Essner (Class of 2023 at Ithaca High School)

Lauren is a senior in high school and is a part of Cornell’s New Visions Program where high schoolers are able to work in labs or participate in veterinary rotations during the school day. She is looking forward to studying Animal Science as a major with Animal Genetics as a minor to use in a career devoted to animal conservation and rehabilitation either as a veterinarian or via research. Currently, her two dogs, Athena and Harley Quin, her flock of chickens, and her guinea pig Mowgli take up her extra time. 


Lauren’s work in the Hedrick lab is enveloped by a study on the astragalus bone’s locomotor relationships to a species' phylogenetics and environment using CT scans. 


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 second year grad student in the Biomedical Sciences MS program at LSU. 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.


Jazmine is working with the Hedrick Lab and the Schachner Lab (LSU) to assess the anatomy of veiled chameleon lungs using high resolution micro-CT scans. This includes a complete ontogenetic series of veiled chameleons, including developmental stages.
