We plan to study populations, and theories relevant to them. Population exhibits phenomena that are difficult to deduce from the characteristics of an isolated member. The prevalence of a disease is only indirectly connected to the course of diseases in an individual. To develop concept helpful for understanding populations, we plan to study concrete problems in demography, epidemiology, ecology, and population genetics.

The human population doubled between 1955-1995, while awareness of environmental problems and economic inequalities increased. Though global average fertility rate have declined, since 1970, rapid population growth continues in many of the economically less developed countries. A question that arises naturally, is How many people can the earth support ? Numerical value of this question, over the last half century, have ranged from one billion to more than one thousand billion; a wide difference is due to human carrying capacity and vastly different assumptions.

In Latin America Chagas disease affected millions of people which is an insect born and infectious disease. African Sleeping Sickness is another new world of problems. So far no cure is known for these diseases but it can be avoided by keeping the insect vectors out of human dwellings and by keeping domestic dogs and cats, which are reservoirs of infections, out of bedrooms. ACBR proposes to develop a mathematical model of the risk of transmission to humans based on the data collected.
