Mallory Ladd

Environmental and Climate Sciences


Supervising Faculty: Robert Hettich

Mallory is pursuing her PhD in Energy Science and Engineering with a concentration in analytical chemistry and climate science applications. Broadly, her research interests include using the molecular specificity of advanced analytical techniques to probe the underlying mechanisms that control larger-scale ecological processes, with an emphasis on how those processes may change under a warmer climate. Working on the Next-Generation Ecosystems Experiments (NGEE-Arctic) project at Oak Ridge National Laboratory, Mallory is developing high performance liquid chromatography (HPLC) and high-resolution nano-electrospray ionization (nanoESI) tandem mass spectrometry (MS/MS) techniques to characterize and monitor low molecular weight soil organic matter. Her dissertation aims include elucidating the rates and controls over nitrogen speciation and transformation in permafrost soils from the Alaskan Arctic, to better understand how the availability of this limiting nutrient may impact microbial dynamics and greenhouse gas release from high-latitude systems under warmer conditions in the future. Alongside her scientific research, Mallory is also interested in energy and environmental policy, science communication, traveling, running, kayaking, cinema, and spending time with her family and pets.
