Research Interests: My research combines original theory with laboratory and field
experiments to study the ecology and evolution of reproductive and
life-history strategies in teleost fishes. Most of my current research
focuses on conflicts of interest (e.g. "the battle of the sexes,"
intrasexual competition for mates, parent/offspring conflict), and
their implications for the fish mating systems. My research program
integrates several levels of biological organization and includes
elements of population biology, sensory physiology, and genetics. |

Interests: My research focuses on variation in life history
and mating strategy in a group of simultaneously hermaphroditic
fishes (Serranidae: Serraninae) that use an interesting
egg-trading reciprocity behavior. My research is conducted at
Smithsonian Tropical Research Institute's Bocas Research Station
in Panama. My study species, Serranus tortugarum, is a
small site-attached zooplanktivore that feeds in groups on
protected inter-island reefs of the Caribbean that vary in
habitat characteristics and predator regimes. I have
found that gonadal allocation, body size distribution, and
mating behavior vary among populations, and I
am investigating how ecological variables, such as
density and predation risk, can explain these observations.

Interests: My research, conducted in Bruce
O'Hara's lab, focuses on the interactions between meditation,
sleep and performance in terms of Reaction Times at the
Psychomotor Vigilance Task (PVT). One question is whether
meditation can pay off sleep debt, as has been claimed by some
practitioners. Another question, is whether meditation improves
performance on tasks that are sensitive to sleep debt, such as
reaction time on a Psychomotor Vigilance Task (PVT). Our data
indicate that meditation provides at least a short term
enhancement on PVT performance in both rested and sleep-deprived
meditators, and in both novice meditators trained at the
University of Kentucky and experienced meditators in India. Data
from experienced meditators in India also suggest that
meditation may be able to replace a portion of sleep time, but
cannot totally replace sleep. |
