Joaquin Navajas Acedo

Predoctoral Researcher

Hometown: Madrid, Spain


Research Interests: Joaquin is attempting to understand how, why and where cell polarity is established on the zebrafish lateral line; and how that would help us understand development and disease.



Tatjana Piotrowski, PhD

Principal Investigator

Hometown: Herrenberg, Germany


Research Interests: Dr. Piotrowski says she always liked natural science. Although that could account for her interest in fish, like many embryologists, she is simply awed by watching an embryo develop. “One of the things I love about our work is the beauty of these embryos,” she says. “It is a privilege to sit at the  microscope and see a single cell turn into an embryo—it is an incredibly aesthetic experience.”

Mark Lush, PhD

Research Specialist

Hometown: Louisville, Kentucky


Research Interests: Mark has had a long-standing interest in developmental neurobiology. Mark says, "Zebrafish have proven to be an incredibly powerful model system allowing for the in vivo study of the development of the nervous system.  My research includes two main goals; the discovery of new genes required for sensory hair cell development and regeneration and the elucidation of the cellular signaling pathways used by Schwann cells to control lateral line stem cell proliferation."
