Academic interests

I have been interested in gene regulation, particularly posttranscriptional. Whether a specific mRNA is translated, repressed, or degraded, depends on its interactions with RNA-binding proteins and regulatory RNAs. My laboratory studies how these interactions determine mRNA fate and how posttranscriptional mechanisms control fundamental biological processes. Our main experimental models are the nematode Caenorhabditis elegans (a genetically tractable model) and mammalian cells, which we study using genetics, genomics, biochemistry, and cell biology.

In future research, we will continue investigating novel mechanisms of mRNA regulation. Additionally, we will study molecular mechanisms facilitating cold survival, with exciting biomedical implications.
