2) What aspects of cyanotoxins do you work with (ie. ecological, toxicolocial,
structure, etc.)?
I don't work with cyanotoxins but rather phycotoxins; toxins
generated by marine algae. The toxins don't kill plants generally, as the
name implies, but rather kill animals. For those not familiar with this
field, these toxins include the paralytic shellfish poisons (PSP) and
diarretic shellfish poisons (DSP), as well as others. The shellfish merely
are the accumulators of the toxins from the phytoplankton on which they feed.
Since there is some overlap in toxins with those of cyanobacteria,
and I am interested in toxins in general as well, I am quite interested in
what will likely be discussed in Cyano-Tox. I would not be surprised to find
that the toxic cyanobacteria contribute significantly to shellfish toxicity
in some locations.
3) What are some keywords that sum up your research involvements and
interests?
Involved with:
Diarretic shellfish poisons (DSP)
Domoic acid (ASP)
Have interests concerning:
Paralytic shellfish poisons (PSP)
Ciguatera toxins
Brevitoxins

Research Interests: Principally on toxins of marine eukaryotic algae (i.e.
domoic acid production by the marine pennate diatom, Pseudonitschia pungens).
However, I have a research program on the culture of freshwater
cyanobacteria for investigation of production of both known and novel toxins.
This includes work with Microcystis and Oscillatoria spp. I also work with
several cultures of the marine cyanobacteria Synechococcus for research on
phycoerythrin pigments. I work closely with analytical and biological
chemists using HPLC, Mass Spectrometry, and NMR on isolation/identification of
toxins.

I've just started my PhD, so it's all up in the air a bit at the
moment, but generally speaking (as I understand it!) I will be
looking into microbial degradation of microcystins, especially the
variants LY, LW, and LF. Also comparing the toxicity and effects of
these variants on various microbial components (ie. cilliates) of
aquatic systems.
I don't think I can say much more at the moment really.

this, there is the scope for further research into developing bioreactors
for water supply detoxification.
