Research Activities & Interests

I'm an applied entomologist and also a quantitative ecologist. I'm mainly working on the spatially extensive and/or long term data collected in the field. The data is analyzed from the view point of basic ecology, conservation and also pest managements.

Age-structured Models for Pest Insects:
Prof. Nelson (Queen's Univ., Canada, http://post.queensu.ca/~nelsonw/People.html)
Prof. Bjørnstad (PSU, USA, http://asi23.ent.psu.edu/).
