Research interest
Small microRNAs play big roles
"I am focusing on microRNAs research, where I am applying the systems biology approach to uncover its function in cellular signalling pathway."
My research focuses on building and analyzing mathematical models that describe problems in finding the links between cancer and aging. Areas of particular interest include signalling pathway related to cancer caused by the deregulation of p53 and the regulatory dynamics of miRNAs. The mathematical tools that I use include nonlinear dynamics, sensitivity and bifurcation analysis, optimization methods and multiscale-hybrid modeling.
