National University of Singapore
Alan Ziegler’s research addresses the interactions of physical and ecological systems, with water resources serving as a common nexus. His work typically involves developing environmental monitoring programs that facilitate understanding catchment processes, as they vary both naturally and anthropogenically over different spatial and temporal scales.
I am looking for new graduate students who have interest in various aspects of water resource management, environmental health, natural hazards, and/or hillslope/catchment hydrology. In particular, I am interested in exploring the risks of rural populations in developing areas to ingestion of contaminated drinking water, exposure to anthropogenic contaminants (heavy metals and pesticides), exposure water-borne pathogens (e.g., parasites, bacteria). This type of research requires extended fieldwork in foreign countries, language training, and hands-on work with local populations. The research is a multi-disciplinary balancing act, grounded in science, but with an interest in incorporating elements of human geography.

Jimmy Bramante, MSc (2015)
Thesis Title: Quantifying Recent Trends in Seagrass Cover and Biomass in a Stressed Environment, Pulau Semakau, Singapore
Although my thesis primarily focused on seagrass monitoring and remote sensing techniques, my research interests had a broader range. In general I was building limited prior research to connect the health and distribution of coastal organisms to their coastal environments. This allowed me to indulge in some eclectic methods, from harvesting seagrass, to counting phytoplankton, measuring distance with stereo imaging, manually identifying and measuring thousands of corals from video transects, supervised classification of low resolution satellite images, non-linear optimization of hyperspectral reflectance models.
