Research Interest

Using the zebrafish model, I am interested in understanding the mechanisms underlying rare disorders. More specifically, I aim to investigate the metabolic changes occurring in cardiovascular diseases both before onset and during disease. The zebrafish is a remarkably effective model to investigate such disorders and early development.

In previous projects, I focused on developing zebrafish models for rare metabolic disorders such as neurotransmitter deficiencies and urea cycle disorders, as well as characterizing the mechanisms underlying CHARGE syndrome caused by mutations in the CHD7 gene.
