About the PNAS Member Editor
Name Wachter, Kenneth W.
Location University of California, Berkeley
Primary Field Social and Political Sciences
Secondary Field Applied Mathematical Sciences
 Election Citation
One of the leading mathematical and statistical demographers of his generation, Wachter has made fundamental contributions to the modeling of population processes, especially microsimulation in historical and contemporary demography and the dynamics of unstable and nonlinear population processes. His work has led to parallel efforts in Britain and elsewhere.
 Research Interests
As a mathematical demographer and statistician, I study systematic constraints and random influences that shape the structure of human populations. I helped develop methods of computer simulation to understand the rarity of coresident family members in pre-industrial English households. With these methods, I am now forecasting the kin and family support available to new generations of elderly in the next century. Working in "nonlinear" demography, I have identified mechanisms that give rise to specific kinds of cycles in fertility and population growth. I am currently interested in patterns of mortality at extreme ages shared between humans and other species, trying to reconcile them with statistical models for long-term processes of demographic change.
