Snap Talk by Tom Cassidy

Abstract: For a decade I have studied abstract mathematical structures called non-commutative rings. While these fascinating objects play an important role in modern mathematical theory, for most people they are intangible concepts with no bearing on everyday life. When I was offered a job at the Max Planck Institute for Demographic Research in Germany, I jumped at the opportunity to learn a new subject and work in a concrete field that has been described as "birth, death and mathematics." I will discuss the interdisciplinary nature of demography and highlight some of my research related to changes in mortality and population growth.
