Areas of interest

Insect population ecology. The principal problem in this area is to predict population changes in space and time. Mathematical modeling is the main tool in population ecology (see my paper). Currently I am mostly interested in modeling of spatio-temporal population dynamics and in spatial analysis population distribution using geostatistics. I am working with the problem of gypsy moth spread in North America. The results of my work are being implemented in the Slow The Spread project.

• Optimizing the use of barrier zones to slow the spread of gypsy moth. See Decision Support System for the Gypsy Moth.
• Delineation of population boundaries from sample data and measuring population spread rate.
• Mating success of gypsy moth females in sparse populations.
• Gypsy Moth Life System Model (a complex model of local population dynamics).
• Population stability measures.
• Life-system approach in population studies.
• Optimization of biological control.
• Fall webworm (Hyphantria cunea) population dynamics.
• Pine sawflies (Diprion pini, Neodiprion sertifer) population dynamics.

Theoretical biology. Notions and methods in theoretical biology are still in the process of development. The main problem is "what is life?". My idea is that living systems can be defined as systems that use internal and external information for self-maintenance and self-reproduction.

• Biosemiotics (semiotics=theory of signs).
• Theory of Self-Reproducing Systems.
• Other papers on biosemiotics
• Iulius Shreider on systems theory
• Concept of Time in Biology (review of Meyen's theory).
• Beklemishev on Theoretical Biology and Ecology
• Wings on hind legs! (wonderful reptilia found by my father)
