Research Description:

We use the fission yeast Schizosaccharomyces pombe as a model system. Working with fission yeast has many advantages, including the ease of genetics and cell biology, availability of powerful functional genomics tools, and extensive homology between its genes and human genes.

We are carrying out research on the following topics:

1. Studying the mechanisms of DNA double strand break repair.

2. Dissecting the molecular machineries of autophagy and related trafficking pathways.

3. Systematic screening of genetic interactions.
