Current Research Interests

Nik just successfully completed his doctoral dissertation in Entomology (Dec. 2011). Dissertstion topic: Biology of tachinid parasitoids (Diptera) and their role in biological control of leafrollers (Tortricidae), in Washington tree fruit.

Nik's interests include:

  • Biological control of insects and weeds
  • Population ecology and life table analysis
  • Chemical ecology of tortricid moths
  • Reproductive physiology in insects
  • Plant community dynamics
  • Geostatistical analysis
