In general, what am I interested in?

I work on mathematical ecological problems.  Some of them are theoretical or analytical. Others involve the analysis of empirical data, in collaboration with (highly valued) collaborators. I tend to choose theoretical problems with empirical implications, and empirical problems that raise interesting theoretical issues.  I do not limit myself to particular taxa or habitats. It's more fun that way. Because I have been working with them for a long time, many of my projects involve matrix population models. These are a particularly nice way to investigate the dynamics of structured populations (by age, by stage, or by other characteristics).  But matrix models are not the only framework in which one can study structured populations, so I have no argument with the use of partial differential equations, renewal equations, delay differential equations, or integrodifference equations. I make frequent visits to the Max Planck Institute for Demographic Research in Rostock, Germany, where I interact with human demographers interested in biodemography.

Descriptions of some of my current projects appear below.

You can find references to publications on most of these projects on my CV elsewhere on this web page.
