Research Interests

My research interests are motivated by applications. My recent research emphasis has been on the tail behavior of multivariate non-Gaussian phenomena and its influence on risk measures. The former incorporates the tail behavior of margins (e.g., tail heaviness and skewness) and the limiting properties of their dependence structures (e.g., tail dependence and asymptotic independence); the latter concerns issues that are meaningful to finance and insurance. In addition to applications in insurance and finance, the study of multivariate non-Gaussian phenomena is beneficial to other research fields, such as environmetrics and network data analysis.
