Raúl Perez-Estrada
Post Doctoral Scientist

Jared Tangeman
Jared recently received in Ph.D 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. Jared looks forward to pursuing his career at Johns Hopkins University this upcoming year.

Graduate student researchers



Carlos Mario Charris Dominguez

Stacy Bendezu
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!​
