My research focuses on how law relates to the natural world, particularly in the field of environmental law. Terms and concepts originating in the natural sciences permeate the law. This is especially true in “new” legal fields like environmental and medical law, but is also true in many “classic” fields such as tort law, in which, for example, scientific expertise is often needed to determine risk or fault. Differing interpretations of these terms and concepts in different disciplines affect decision making and make it difficult to know whether the law is being complied with. When scientific concepts are made part of the law, reference to the natural sciences is often necessary in order to properly understand or apply the law. If judges or other decision makers misunderstand or misuse natural science, the laws’ ability to achieve legislative goals may be hindered. I try to find ways to improve the interaction between those working with law and natural science in order for the legal system to be better able to protect the environment.
