Biography
Our research focuses on materials for use in extreme environments and can be applied to materials for use in aircraft engines, rocket engines, energy conversion technologies, and thermal protection systems. We first create critical aspects of the use environment in the lab such as high temperatures (up to 2000°C), reactive gases (oxygen, water vapor), and high flow rates ( hundreds of meters per second). We characterize materials before and after exposure using techniques as simple as weight change to sophisticated state-of-the-art microscopies and spectroscopies. Experiments are linked with theory and computational techniques where possible. We ask these questions about material behavior: What reactions occur and why? How fast do they occur? Can we predict material lifetimes? How can we make better materials?

Courses
Credits: 1–3
Special tutorial with a topic declared in advance. The topic, work plan, and conditions are arranged by contract between instructor and student and approved by the department Chair, with a copy to be filed in the department office.
Credits: 3
Advanced undergraduate course on topics not normally covered in other course offerings. The topic usually reflects new developments in the materials science and engineering field. Offerings are based on student and faculty interests.
Credits: 1–6
A fourth year project in MSE, under the supervision of a faculty member, is designed to give undergraduate students an application of principles learned in the classroom. The work may be experimental or computational, and the student is expected to become proficient in techniques used to process, characterize, or model materials. The project should make use of design principles in the solution of a problem. Six hours in lab per week, notebook. Prerequisite: 4th year standing and prior approval by a faculty member who is project supervisor.
Credits: 3
Emphasizes the understanding of thermal properties such as heat capacity, thermal expansion, and transitions in terms of the entropy and the other thermodynamic functions. Develops the relationships of the Gibbs and Helmholtz functions to equilibrium systems, reactions, and phase diagrams. Atomistic and statistical mechanical interpretations of crystalline and non-crystalline solids are linked to the general thermodynamical laws by the partition function. Nonequilibrium and irreversible processes in solids are discussed. Prerequisite: Instructor permission.
Credits: 3
An introduction to basic kinetic processes in materials and develops basic mathematical skills necessary for materials research. Students learn to formulate the partial differential equations and boundary conditions used to describe basic materials phenomena in the solid state including mass and heat diffusion in single- and two-phase systems, the motion of planar phase boundaries, and interfacial reactions. Students develop analytical and numerical techniques for solving these equations and apply them to understanding microstructural evolution. Prerequisite: MSE 6230.
Credits: 3
A study of special subjects related to developments in materials science under the direction of members of the staff. Offered as required under the guidance of a faculty member.
Credits: 1–12
Formal record of student commitment to master's thesis research under the guidance of a faculty advisor. May be repeated as necessary.
Credits: 1–12
Formal record of student commitment to master's thesis research under the guidance of a faculty advisor. May be repeated as necessary.
Credits: 1–12
Formal record of commitment to doctoral research under the guidance of a faculty advisor. May be repeated as necessary.
Credits: 1–12
Formal record of student commitment to doctoral research under the guidance of a faculty advisor. May be repeated as necessary.
Credits: 1–12
Formal documentation of faculty supervision of dissertation research. Each full-time resident doctoral student in mechanical and aerospace engineering is required to register for this course for the number of credits equal to the difference between his or her regular course load (not counting the one-credit MAE 8591 seminar) and 12.
