About the Lab
We investigate the behavior of elements and materials in natural and engineered environments, with a focus on processes occurring at the micro- to nanoscale.
Our research integrates environmental geochemistry, geomicrobiology, and advanced analytical techniques to understand how minerals, particles, and radioactive materials form, transform, and evolve.
By combining field studies, laboratory experiments, and atomic-scale observations, we aim to bridge microscopic mechanisms with broader environmental and geological processes.
Our work contributes to addressing key challenges such as environmental contamination and nuclear waste management.
Research Overview
Our research aims to understand the behavior of materials in environmental and geological systems by linking atomic-scale processes to macroscopic phenomena. We focus on fundamental mechanisms that control the fate of elements, with applications to environmental sustainability, nuclear waste management, and critical mineral resources.
1. Environmental Geochemistry
We investigate the chemical behavior of elements in natural environments, including water–rock interactions, trace element mobility, and redox processes. Our work aims to understand how contaminants and nutrients are transported and transformed in environmental systems.
2. Radiological Materials and Nuclear Waste
We study radioactive particles and materials relevant to nuclear waste management, including those derived from nuclear accidents such as Fukushima. Our research focuses on their formation, structure, and long-term stability in environmental and geological settings.
3. Nanoscale Characterization
We use advanced analytical techniques, such as electron microscopy and spectroscopy, to characterize materials at the nano- to atomic scale. These approaches allow us to directly observe structures and processes that control material behavior.
4. Nanoscale Geoscience of Critical Minerals and Noble Metals
We investigate the formation and distribution of critical minerals and noble metals at the nanoscale. Our research provides insights into how these elements are concentrated and transformed, contributing to resource exploration and sustainable utilization.
5. Geomicrobiology
We explore the roles of microorganisms in geochemical processes, including mineral formation and dissolution, and microbe–mineral interactions that influence element cycling and environmental behavior.
