Microbial ecology of wastewater treatment
Like many other areas, Long Island has a long-term problem with poor on-site wastewater treatment leading to nitrogen pollution of groundwater and coastal ecosystems. The New York State Center for Clean Water Technology (CCWT, https://www.stonybrook. edu/cleanwater/) is working to solve this problem. Working with Prof. Jackie Collier and CCWT, this project offers experience in microbial community ecology using methods of rRNA barcoding and metagenomics. The work will be focused on practical applications, such as how best to provide reliable and cost-effective wastewater treatment, that are informed by theoretical considerations of microbial community assembly, such as how environmental selection and stochastic processes determine ecosystem structure and function.
Physiological ecology of labyrinthulomycetes
Although many marine biologists and oceanographers have never heard of them, labyrinthulomycetes are an abundant and diverse group of osmoheterotrophic marine protists playing important roles in marine food webs and biogeochemical cycles. Prof. Collier’s group is developing molecular genetic tools to investigate the physiological ecology of these organisms. Our goals are to use these tools to understand in more detail the complex life cycles of labyrinthulomycetes and investigate unusual aspects of their biology such as their production of carotenoids and involvement in diseases of some marine plants and animals.
