Research

research overview

The overarching theme of our research is to develop systematic data-driven technologies for design and characterization of advanced materials and energy systems. We strive to undertake a comprehensive approach to emerging problems in engineering mechanics involving rigorous mathematical analysis, laboratory experiments, and computation. Our current research involves three focal areas: (1) inverse scattering in complex and uncertain environments, (2) data-driven design of materials with tailored dynamic functionalities, (3) multiscale model discovery of randomly structured composites.

Teaching

courses taught

CVEN 2121 - Analytical Mechanics 1
Primary Instructor - Fall 2023 / Fall 2024
Applies mechanics to the study of static equilibrium of rigid and elastic bodies. Includes composition/resolution of forces; moments/couples; equivalent force systems; free-body diagrams; equilibrium of particles and rigid bodies; forces in trusses/beams; frictional forces; first/second moments of area; moments and products of inertia. Degree credit not granted for this course and GEEN 2851 and MCEN 2023.
CVEN 3111 - Analytical Mechanics 2
Primary Instructor - Spring 2022 / Spring 2023 / Spring 2024
Studies the motion (kinematics) of particles and rigid bodies, and the forces that cause the motion (kinetics). Newton's laws as well as energy methods are used to study the motion of particles and rigid bodies in two and three dimensions. Degree credit not granted for this course and MCEN 2043.
CVEN 3718 - Geotechnical Engineering 2
Primary Instructor - Spring 2019 / Spring 2020 / Spring 2021
Covers stress analysis and plastic equilibrium, sheer strength of soil, bearing capacity, lateral earth pressures, slope stability and underground construction. Analysis and design of shallow and deep foundations, retaining walls and other earth and rock structures. Selected experimental and computational laboratories.
CVEN 5111 - Structural Dynamics
Primary Instructor - Fall 2018 / Fall 2019 / Fall 2020 / Fall 2021 / Fall 2022
Focuses on the response of single- and multi-degree of freedom structures subjected to harmonic, impulsive and arbitrary loads (including earthquake base excitation). Sources and modeling of damping will be discussed. Analytical and numerical solutions will be considered for both linear and nonlinear structural systems. Elastic and inelastic response spectra will be discussed.
CVEN 5151 - Wave Methods for Design and Characterization of Advanced Materials
Primary Instructor - Spring 2023
Covers key theoretical concepts and applications of wave propagation with the focus on ultrasonic scattering. The course material includes: (i) dispersion analysis for design and characterization of materials with random and periodic microstructure, and (ii) advanced elastodynamic formulations rooted in 2D and 3D boundary integral equations for the purpose of inverse scattering and imaging. The course is intended to be self-contained, research-oriented and accessible for multidisciplinary audience.
