Research Interests
Our research focuses on algae and
their role in managed aquatic systems. The understanding
and control of algal diversity in aquatic systems is a
central focus of most projects in the laboratory.
Culture identification and physiology of fresh- and
brackish-water algae are a continual part of the
laboratory procedures. Unialgal and axenic cultures are
isolated and maintained for taxonomic investigations.
Currently we are working on the development of a
selective algicide for the aquaculture industry. The
development of this product, Solricin 135, is the result
of a long-term experiment to identify and bioassay
allelopathic compounds from aquatic plants. Our lab
works jointly with colleagues from USM's Department of
Chemistry, the Bureau of Marine Resources and the Delta
Branch Experiment Station. The sharing of
instrumentation, financial and human resources expands
our research capabilities. The laboratory furnishes
partial support for graduate and undergraduate students
and has assisted 10 doctoral and over 20 master's
students in completing degrees.
