Areas of Interest
As the accumulation of knowledge about the agents of life has been increasing exponentially, there are clear signs about us that biologists are becoming aware that we are in great need of efforts to understand living systems more fully. Those on the cutting edge of science are realizing that it may be time to reconsider Schrödinger's question, What is life? Both reductionism and globalism (i.e., the whole is more than the sum of the parts) are being considered as leading to deeper understandings. In the 21st century integrative biology will become truly integrative as it combines the information about agents gathered by the reductionists in the last half of the 20th century with the global tendencies of complexity research to formulate laws that explain emergent properties characteristic of complex living systems.
Our research team is working to define the role of genetic variation in determining variation in health in the human population at large. Information from population-based samples is being used to address the questions that follow from the reality discussed above. In particular we are asking which variations in which genes, in which environments, influence susceptibility to human disease? Data from the genome level, through intermediate biochemical and physiological levels to the clinically defined endpoint level are available for researching this question.
