Chemical reactions between fluids and minerals create the environments that are uniquely characteristic of Earth’s surface. For example, chemical weathering reactions support the growth of soils and organisms and regulate the flow of elements to the oceans. The rates of these reactions also control the release and storage of natural and human-derived contaminants. Over geologic timescales, mineral-fluid reactions have helped to maintain a mostly habitable planet. Over human timescales, these reactions will regulate our ability to use Earth’s resources, such as soils, waters, and minerals.
My research focuses on the rates of reactions in different environments using a combination of geochemical tools, including isotope geochemistry, geochemical and hydrologic modeling, and geochronology in order to address the following themes: (1) defining the controls on mineral-fluid reactions rates in the environment (2) finding new approaches to use mineral-fluid reactions to safely store carbon dioxide in the subsurface; and (3) development of isotopic approaches to study mineral-fluid reactions in the environments of Earth’s past. To support these research themes, I have constructed a new mass spectrometer and clean lab facility capable of high precision geochemical and isotopic measurements, and teach a number of classes and short courses on reactive transport.
My teaching focuses on introducing students to the questions and major challenges in low-temperature and environmental geochemistry, and the application of isotope geochemistry to environmental and geologic problems. In order to introduce incoming students to Earth surface processes, materials and geochemistry, I am also teaching a freshman seminar on forensic geoscience. At the graduate level, I offer classes on isotope geochemistry and modeling of environmental transformations and mass transfer processes (i.e., subsurface reactive transport).

Associate Professor of Mechanical Engineering
BioOur research is broadly defined by multiphysics problems in fluid dynamics and transport engineering. Our work contributes to the understanding of these problems primarily through theoretical tools such as techniques of applied mathematics as well as massively-parallel simulations. Numerical simulations enable quantitative visualization of the detailed physical processes which can be difficult to detect experimentally. They also provide quantitative data that guide the development of reduced-order models, which would naturally induce insight for design, optimization and control. Most of our work involves complementary interactions with experimental groups within and outside of Stanford. Specific current research topics include:
(1) Electro-convection and microscale chaos near electrochemical interfaces
(2) Particle-laden flows with applications in solar receivers
(3) Applications of superhydrophobic surfaces for drag reduction of turbulent flows
(4) Micro-bubble generation by breaking waves
(5) Electrokinetics of micropores and nanopores

BioThe Melosh group explores how to apply new methods from the semiconductor and self-assembly fields to important problems in biology, materials, and energy. We think about how to rationally design engineered interfaces to enhance communication with biological cells and tissues, or to improve energy conversion and materials synthesis. In particular, we are interested in seamlessly integrating inorganic structures together with biology for improved cell transfection and therapies, and designing new materials, often using diamondoid molecules as building blocks.
My group is very interested in how to design new inorganic structures that will seamless integrate with biological systems to address problems that are not feasible by other means. This involves both fundamental work such as to deeply understand how lipid membranes interact with inorganic surfaces, electrokinetic phenomena in biologically relevant solutions, and applying this knowledge into new device designs. Examples of this include “nanostraw” drug delivery platforms for direct delivery or extraction of material through the cell wall using a biomimetic gap-junction made using nanoscale semiconductor processing techniques. We also engineer materials and structures for neural interfaces and electronics pertinent to highly parallel data acquisition and recording. For instance, we have created inorganic electrodes that mimic the hydrophobic banding of natural transmembrane proteins, allowing them to ‘fuse’ into the cell wall, providing a tight electrical junction for solid-state patch clamping. In addition to significant efforts at engineering surfaces at the molecular level, we also work on ‘bridge’ projects that span between engineering and biological/clinical needs. My long history with nano- and microfabrication techniques and their interactions with biological constructs provide the skills necessary to fabricate and analyze new bio-electronic systems.

Professor of Mechanical Engineering
BioProfessor Mitchell's primary area of research is concerned with characterizing the physical and chemical processes that occur during the combustion and gasification of pulverized coal and biomass. Coals of interest range in rank from lignite to bituminous and biomass materials include yard waste, field and seed crop residues, lumber mill waste, fruit and nut crop residues, and municipal solid waste. Experimental and modeling studies are concerned with char reactivity to oxygen, carbon dioxide and steam, carbon deactivation during conversion, and char particle surface area evolution and mode of conversion during mass loss.
Mitchell’s most recent research has been focused on topics that will enable the development of coal and biomass conversion technologies that facilitate CO2 capture. Recent studies have involved characterizing coal and biomass conversion rates in supercritical water environments, acquiring the understanding needed to develop chemical looping combustion technology for applications to coals and biomass materials, and developing fuel cells that use coal or biomass as the fuel source. Studies concerned with characterizing coal/biomass blends during combustion and gasification processes are also underway.
