Biography

Zachary Redman, Ph.D. is currently responsible for teaching general and analytical chemistry. His
research interests center on the application of modern analytical chemistry techniques and instrumentation
to advance our understanding of environmental processes and ecotoxicology. Current research projects
include the study of (1) oxidized polycyclic aromatic hydrocarbon photochemical formation and
dissolution in simulated oil spills and their bioaccumulation in mussels by coupled targeted quantitative
and non-targeted screening methods; and (2) photochemical mechanisms and product formation of current
and emerging sub-Arctic aquatic contaminants under high-latitude conditions. Additional efforts to
establish workflows for metabolomics and microplastics analysis in the UAA ASET Lab are ongoing.

Teaching Responsibilities

• CHEM A106: General Chemistry II
• CHEM A218: Experiential Learning: Quantitative Chemical Analysis
• CHEM A418: Experiential Learning: Chemical Instrumentation and Methods
