Research Focus
Goal: To elucidate the mechanisms that regulate cell turnover while preserving barrier function in epithelia and identify specific alterations that go awry during pathogenesis.
How we do it: Use the powerful cellular and genetic tools available in the developing zebrafish to dissect cell turnover in a living epithelial tissue.

Oscar Ruiz, Ph.D. receives first place in the 2016 Nikon Small World Photo Competition
Ruiz brings the world face-to-face with his research on facial development and cellular morphogenesis with his winning image of a four-day-old zebrafish embryo. Ruiz uses the zebrafish to study genetic mutations that lead to facial abnormalities such as cleft lip and palate in humans in the lab of George Eisenhoffer, Ph.D. Click here to read more and see this award winning photo.
