Specific Interests

My research explores the reciprocal relationships between organisms and the environment by focusing on the fundamental currency that connects them — elements. By combining approaches from ecological stoichiometry and ionomics, I study how human mobilization of elements influences organismal ecology and evolution, and how these responses feed back to alter biogeochemical cycling. This cross-scale approach combines laboratory experiments examining how elemental imbalances alter organismal elemental phenotypes and life-history with geographical population and ecosystem-level studies, using mass balance principles to understand how these processes control the flows of elements through the environment.
