PhD Research - Adeyemi Adeleye

MESM UC Santa Barbara; BS Microbiology, Obafemi Awolowo University (Nigeria)

Adeyemi Adeleye is interested primarily in the fate of emerging pollutants (particularly engineered nanomaterials) in natural aquatic systems. The use of engineered nanomaterials in consumer and industrial products is growing rapidly, and there is no doubt that these materials will be released into the environment. Understanding the fate and exposure levels of these materials in the environment is necessary for proper risk assessment. For his thesis, Adeyemi is studying the influence of extracellular polymeric substances synthesized by bacteria and phytoplankton on the fate and transformation of widely used engineered nanomaterials. In addition, he plans to investigate how solution chemistry affects the surface interactions between engineered nanomaterials and microorganisms.
