Research interests in the Janzen Lab involve the study of ecology and evolution, including mechanistic work at the molecular/genomic and organismal levels, field studies that document the importance of phenotypic variation, and a comparative view of the long-term consequences of this variation. To do so, we often integrate molecular and quantitative genetic/genomic techniques with experimental laboratory and field studies, largely focusing on the impact of environmental and genetic/genomic factors in mediating the expression of physiological, behavioral, and life-history traits. Using these conceptual approaches in concert with comparative and computational approaches enables us to assess important biological issues, including 

 

  1. the biological significance of diverse sex-determining mechanisms, 
  2. the impacts of environmental and genetic/genomic factors on variation in early life-history traits, and 
  3. the current and historical genetic/genomic and demographic structure of populations, with an emphasis on elucidating adaptive processes and solving conservation concerns.
