Anthony Sallese

Post Doctoral Scientist

Picture1.png

Tony obtained his PhD at Cincinnati Children’s Hospital while working on a rare lung disease called Pulmonary Alveolar Proteinosis. Using patient derived samples and mouse models, he characterized a disease process similar to atherosclerosis which occurs in the lungs of patients with mutations in the cytokine receptor or autoantibodies for GM-CSF. Since coming to Miami University Tony has been working on characterizing the differences in regenerative potential between the dorsal and ventral iris of the Red Spotted Newt. His group uses a number of cellular and molecular approaches both in vitro and in vivo to study the remarkable ability of these amphibians to regrow body parts.

Jared is a 5th year Ph.D. student studying ocular development & disease. Using the embryonic chicken, newt, and axolotl, he studies the epigenetic landscape governing the formation of ocular tissues, and how this landscape behaves in response to injury. Jared serves as the president of SACNAS at Miami University

Stacy Bendezu

Research International Scholar

Stacy_pic.jpg

Stacy is an international scholar from Perú, she received her BSc. in Genetics and Biotechnology from Universidad Nacional Mayor de San Marcos (Perú), and her current focus in data science is Transcriptomics.
In addition to regenerative biology, outside of the lab, she enjoys travel and taking wildlife photography. She plans on pursuing further graduate studies in regeneration and wants to meet an axolotl in person!
