I am a curious being. As a researcher, when you answer one research question, you ask another three. I am a big thinker and love to combine scientific theory, community and environmental applications. My key research interests include:

1. Wastewater treatment

2. Environmental toxicology

3. Algal feedstock generation

4. Environmental applications of Geographic Information Systems (GIS)

I was just awarded a Campus Research and Publication Fund for a bioprospecting project. I am hoping that within this academic year, the research team that I am leading, would be able to examine bio- products from a few algal species indigenous to Trinidad and compare them to commercial species. This project will be multi-disciplinary and have the involvement of students from industrial, environmental engineering and Department of Life Sciences Departments.

I have reviewed a few technical papers for Ecological Engineering and African Journal of Biotechnology. I have authored and coauthored a number of publication. See below for a selected list of publications.
