Our expanding knowledge of cancer genomes has led to the development of more-effective therapeutic strategies. Tumor profiling has shown clinical benefits to improve precision medicine. Circulating tumor DNA shed from the tumor into the body fluids open up tremendous opportunities for safe, more-effective noninvasive cancer management across different cancer types.

The focus of the Tsui lab is to study the molecular profiles of cancer using circulating tumor DNA and other nucleic acids in plasma and body fluids for noninvasive management of treatment responses and guiding personalized medicine. We are particularly focusing on types of assays that have the potential for immediate clinical implementation in the next 1-2 years.

Open Positions

Computational Biologist

We are looking for a computational biologist to join our team to (i) study the clinical utility of cell-free DNA and RNA in cancer types including prostate cancer, ovarian cancer, lung cancer, pediatric cancers and lymphoma patients, (ii) study the incorporation of mutation detection by targeted sequencing and fragment size analysis in whole genome sequencing of cell-free DNA for the noninvasive detection of minimal residual disease in cancer patients.
