Philosophical Issues in Psychiatry III: The Nature and Sources of Historical Change (Paperback) (ISBN-13: 9780198725978)

The major focus of Professor Kendler's research is in the genetics of psychiatric and substance abuse disorders. Two major methodologies are used in this research. The first involves large population based twin samples. In these twins, we address the aggregate role of genetic and environmental factors. We seek to understand how these factors interact and correlate, and how, through development, the vulnerability to psychiatric illness and drug abuse is expressed. I have focused my work with twin samples from Virginia - in particular the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders - but also worked with twin samples from Norway, Sweden and Holland. My work has focused on a wide range of disorders including major depression, anxiety disorders, eating disorders, externalizing behaviors, alcoholism, and drug abuse. I have worked a lot toward understanding the genetic and environmental sources of comorbidity of psychiatric and substance use disorders.
