Research Focus:
My focus is developing state of the art statistical methodology that are used to understand the dynamics of environmental phenomena and health variables, in particular. The statistical models and inferential methods I develop are general in their applications and mostly Bayesian in their philosophy and technicality. Some examples of their specific uses are joint modeling of dependent spatially and temporally dynamic atmoshperic/environmental/molecular variables, modeling continuous physical phenomena depending on time-dependent evolutions of other related variables, predicting the directions of spatially dynamic phenomena (such as wind direction and movement of migratory birds). Current research revolves around risk modeling for breast cancer and mammographical images.
Teaching:
I am experienced in teaching foundation of statistical theory, particularly mathematical statistics, statistical inference and theory of Bayesian analysis
