Project description

I study protein translation profiles of human normal and cancer cells and how they are affected by using different drugs. I use transcriptome-scale ribosome footprint data to investigate the eIF4A-dependent mechanism of translational control that contributes to oncogenesis and underlies the anticancer effects of drugs. I am also developing analysis tools to identify the genes featuring either one of the two changes in different physiologic or pathologic conditions:
1) translational efficiency and
2) distribution profile of ribosome occupancy on mRNA.
By combining observation of translation profile changes with cancer genome data, I am aiming to estimate the drug effects on the tumor for patients with different germline and somatic variants.

Motivation for participating in the network

In recent years, tremendous progress has been made in biomedical research. This is spurred by not only the advent of new biological technologies, but also through the application of interdisciplinary methods to biomedical problem contexts. In particular, machine learning and statistical methods have enabled the analysis and interpretation of large datasets generated from sequencing experiments. The future of personalized medicine relies on the intersection of high-quality data with state of the art analytical methods. I believe the advantage of participating in ITN will provide me the opportunity to work at the frontier of personalized medicine together with all involved labs in its network.
