I am interested in a broad range of biological inquiry. Much
of my research is aimed at understanding how different environments can influence
the physiological characteristics of the animals inhabiting them. Currently I am undertaking a
series of projects that are charged with understanding how animals
physiologically cope with the pressures of starvation. Few attempts
have been made to
document the physiological changes associated starvation and fasting in all
but a handful of species. Since all multicellular animals are heterotrophic,
starvation related mortality is a potentially ubiquitous fate for each of
them. Unfortunately, almost nothing is known about fasting physiology in
many groups of animals.
Physiological responses to fasting are well studied in humans, and
investigations into animal fasting/starvation generally compare the
physiological responses of a given animal to that of humans. While this
approach is interesting from a clinical perspective, it neglects the
enormous diversity of physiological responses animals have evolved to cope
with fasting.
Even comparative studies of fasting physiology are generally
limited to relatively closely related taxa, which may show minimal or
superficial variation, and thus offer little insight into the evolutionary
history of ecological adaptation. My research has recently demonstrated that
different types of animals employ widely varied strategies for surviving the
challenges of food limitation, and my current goal is to understand why
animals have evolved so many solutions to a single omnipresent problem.
