Conducting research in the field of bioinformatics, Dr. Wang explores the visual representation of DNA, specifically the method known as Chaos Game epresentation. This method is useful in researching very long sequences of DNA, including entire genomes.

Research Interests

I am currently conducting research in the field of bioinformatics. This is essentially a cross between biology and computer science. My particular interest evolved as a result of my trying to interpret very long DNA sequences. The information is so long that it is hard to interpret without some sort of visual representation, which is what I am exploring. Currently, there are several ways to visually represent DNA, but I am investigating a method known as CGR (chaos game representation). This method displays the primary DNA sequence organization for a sequence of any length, including entire genomes.

The goal of my research is to compare similarities and differences between species using bioinformatics. This is useful for classifying species in a phylogenetic tree. I am trying to find genomic signatures that can relate two species based on similar DNA. In other words, finding a genomic signature is finding something specific to a species, distinguishing it from all other species. The CGR method visually shows these genomic signatures. When comparing two species that share similar DNA, one can see the similarities in patterns making a definite link between the two.I am applying my newly developed techniques in bioinformatics to the phylogenetic analysis of the Potato Virus Y population (PVY). On Prince Edward Island, potatoes are one of the main agricultural crops grown, and the PVY virus has many strains, some of which are highly destructive and pathogenic to potatoes, and some of which are harmless. I am working with the Canadian Food Inspection Agency to better understand the evolutionary pathway of this virus. I am trying to identify the relationships among PVY virus strains. The genetic relationships among Canadian PVY strains and strain types are poorly understood and there is a need to identify the origin, spread, and the evolutionary pathway of PVY in Canada.
