Brian A. Lockwood DOE Computational Science Graduate Fellow Ph.D. Student Computational Fluid Dynamics (CFD) Laboratory Department of Mechanical Engineering University of Wyoming Curriculum Vitae Email: blockwoo@uwyo.edu

Hello and welcome to my academic website. My name is Brian Lockwood and I am a former Ph.D. student at the University of Wyoming in the mechanical engineering department. My work was supported by a Department of Energy Computational Graduate Fellowship and was performed under the supervision of Dr. Dimitri J. Mavriplis. The area of my Ph.D. research was computational fluid dynamics with a specific focus on rapid uncertainty quantification for hypersonic flows using gradient-based methods. I am currently working for CD-Adapco as a software developer in their Lebanon, NH office.

Research Interests Hypersonic Flows Adjoint/Sensitivity Methods Uncertainty Quantification Numerical Optimization Nonlinear and Linear Solvers High Performance Computing Novel Spatial/Temporal Discretizations Computational Fluid dynamics and Computational science in general
