Research Interests
Research in my lab focuses on two main areas. One project involves understanding how cell growth is regulated. The other project is aimed at investigating cell adhesion during development. Both projects involve using molecular biology, classical genetics, mutagenesis screens and cell biology methods.

Other publications in this area

We use Drosophila melanogaster (the fruit fly) as an experimental model for these studies.
Why Drosophila?
It's developmentally well-characterized.
It's an excellent genetic system.
Drosophila is easy to manipulate.
Many established techniques are available.
