Philosophy

We recognize that the pursuit of scientific knowledge is not an equitable endeavor. Systematic biases often influence who can pursue academic research. To that end, it is the goal of this laboratory to do our part to make that pursuit equitable. We will do so by making the laboratory an inclusive and diverse workplace by following the below tenets:

Sexism, racism, classism, or other forms of discrimination have no place in the laboratory.
Every member of the lab has a voice, and their voice should be heard.
Inclusivity and diversity will make our team stronger.
Everyone in the laboratory is entitled to appropriate training, resources, and mentorship.

We will make every effort to ensure that our work is robust, reproducible, and accessible.

Research Projects

The roles of ADAR interacting proteins

ADAR edits most of the transcriptome, though editing of only a handful of RNAs is required to supress dsRNA sensing. This project focuses on regulation of A-to-I editing by ADAR interacting proteins.

Targeting ADAR to treat triple-negative breast cancer

Triple-negative breast cancer (TNBC) is the deadliest form of breast cancer. Unlike hormone receptor positive and HER2 positive breast cancer, there are no broadly applicable targeted therapies for TNBC. ADAR is a potential therapeutic target for TNBC. This project focuses on understanding ADAR-dependency in breast cancer and identifying small molecule inhibitors of ADAR.

RNA binding proteins in cancer

This project focuses on understanding the role of RNA binding proteins in cancer, with the goal of identifying vulnerabilities that can be targeted to treat cancer.

Impact of RNA editing or mutations on post-transcriptional regulation in cancer

The fate of a messenger RNA is influenced by multiple cis and trans acting factors. This project focuses on understanding how base editing or mutations influence post-transcriptional regulation of mRNAs.
