My research interests are in the areas of molecular evolution and the way that gene frequencies change over the course of time in populations of organisms. On-going work involves characterizing the way that a gene's context influences the mutations it accumulates as well as determining the role of highly repeated elements that constitute as much as 15% of the DNA within mammalian nuclei. Other studies involve use and development of computer-based expert systems to evaluate DNA evidence in criminal investigations.
We have also developed a technique that allows us to quickly and precisely measure the amount of genetic diversity a population harbors at a molecular level. Since high levels of genetic diversity better allow groups of organisms to respond to stresses they encounter in their environments it is also an excellent measure of the population's vigor and productivity. Environmental insults such as pollution can significantly diminish a naturally occurring population's genetic diversity however and we are currently using out methodology to more closely examine the true impact of such events.
