Biography
The research in Dr. Freimer’s laboratory aims to identify the genetic basis of complex traits, particularly neurobehavioral phenotypes such as bipolar disorder, Tourette Syndrome, and temperament. Together with numerous collaborators the lab has centered its studies around three foci:
1) using genomewide genetic approaches to map neurobehavioral traits
2) developing innovative approaches to phenotype neurobehavioral traits
3) emphasizing the importance of population genetics for gene mapping, particularly the use of population isolates.
