Description of Research Expertise

Research Interests: RNA systems biology, particular as related to non-coding RNAs and cancer biology.

Keywords: RNA, systems biology, cancer, non-coding RNAs

Research Details:
The Raj lab studies the biology of single cells. The primary motivation for studying biological processes on a cell-by-cell basis is the fact that even genetically identical cells can behave very differently. This variability can have consequences in a variety of biological contexts. We aim to understand these differences at the molecular level. We develop and utilize a mix of experimental tools including individual RNA molecules via fluorescence microscopy, high throughput sequencing and molecular biology to make quantitative measurements of cellular behavior.

Rotation Projects: Please contact Arjun for more details.
