I have conducted ecological research on bats on the Caribbean
Islands of Puerto Rico,
and St. John, U. S.
Virgin Islands. Much of this work is concerned with
long-term monitoring of bat populations and the effects that
Hurricanes have on them. In addition, I have worked in the Allegheny National
State Park, and other locations in the Commonwealth of
Pennsylvania. Here, my students and I have been developing
ultrasonic bat survey techniques which may be used to identify
different species of bats by their ultrasonic calls. This
includes the endangered Indiana Bat.
