Research Interests

Today geneticists use more high-throughput technologies in their research. Phenotypic data and genotypic data are even generated on daily basis. The accumulated big data not only provides vigorous opportunities, but also creates challenges for analyses. We have been using statistical genomics-based approaches to face these challenges. Ongoing research include 1) use of general linear model and random model to reduce both false positives and false negatives in gene discovery; 2) genomic approach to predict performance under varied environments; and 3) specific programming to integrate non-CPU (Central Processing Unit) for high performance computation. Our major goal is to develop innovative, cutting-edge statistical methods and computing tools to advance genomic research toward the sustainability of food production and healthcare management.
