Research
Interests
I am primarily interested in stream fish ecology; in particular, the causes
and consequences of movement on growth on survival of Atlantic salmon.
I am using PIT tag technology, mark-recapture theory (Program MARK), and
relational databases to address ecological questions that have relevance
for basic ecology as well as in a fisheries restoration context. [ppt
