Research Interests

My research focuses on the role of Hox genes in nervous system development. The functions of Hox genes as drivers of regional diversification along the head-to-tail body axis are well-studied. In contrast, the later functions of these broadly expressed genes, especially in the maturing nervous system are poorly understood. In the lab, we are currently addressing two major questions:
1. What functions do Hox genes exert in differentiating neurons, and
2. How do Hox proteins achieve functional specificity in individual cells of the nervous system? To this end we are using the embryonic and larval nervous system of the fruitfly Drosophila melanogaster, as well as cell culture, as model systems.

Key techniques: Immunohistochemistry, protein biochemistry, molecular biology, genetics, cell culture

Research system/organismDrosophila melanogaster
