research overview

  • Dr. Marshall's research encompasses physical phenomena in the near-Earth space environment, with common themes of naturally-occurring plasmas and interactions between charged particles and electromagnetic waves. He studies the radio emissions from lightning and uses them to study wave propagation in the ionosphere and magnetosphere. He studies radio wave interactions with meteor plasma through radar measurements and numerical modeling, in order to characterize the parent meteoroid. He studies the Earth's radiation belts, their interaction with waves in the magnetosphere, and the precipitation of these particles into the Earth's upper atmosphere, in order to characterize both the radiation belt populations and their effects on the atmosphere. Finally, Dr. Marshall builds a variety of instruments to make geophysical measurements, including sensitive radio, optical, and X-ray, and energetic electron instruments, for both ground-based and space-based experiments.

Teaching

courses taught

  • ASEN 3300 - Aerospace Electronics and Communications
    Primary Instructor - Spring 2018 / Fall 2020 / Fall 2021
    Provides the fundamentals of electronics and communications widely used in aerospace engineering. Includes analog instrumentation electronics, data acquisition, digital electronics and radio communication.
  • ASEN 4018 - Senior Projects 1: Design Synthesis
    Primary Instructor - Fall 2023
    Focuses on the synthesis of technical knowledge, project management, design process, leadership, and communications within a team environment. Students progress through the design process beginning with requirements development, then preliminary design and culminating with critical design. Offered fall only.
  • ASEN 4028 - Senior Projects 2: Design Practicum
    Primary Instructor - Spring 2024
    Focuses on the fabrication, integration, verification and validation of designs produced in ASEN 4018. Students work within the same teams from ASEN 4018. Offered spring only.
  • ASEN 4519 - Special Topics
    Primary Instructor - Fall 2018
    Studies specialized aspects of the aerospace engineering sciences or innovative treatment of required subject matter at the upper-division level. Course content is indicated in the online Schedule Planner. Department enforced prerequisite varies.

  • ASEN 5335 - Aerospace Environment
    Primary Instructor - Spring 2021 / Spring 2022 / Fall 2023
    Examines the components of the solar-terrestrial system and their interactions to provide an understanding of the re-entry and orbital environments within which aerospace vehicles operate. Includes the sun, solar wind, magnetospere, ionosphere, thermosphere, radiation belts, energetic particles, comparative environments (Mars, Venus, etc.), orbital debris, spacecraft charging, particle effects on systems, shielding, and satellite drag. Recommended prerequisite: Senior or graduate standing in engineering or related physical sciences.
  • ASEN 5440 - Mission Design and Development for Space Sciences
    Primary Instructor - Fall 2019
    Brings science and engineering students together to develop the multidisciplinary skills required to create a successful proposal to develop a NASA-funded small space mission. Goals: 1) develop the proposal science objectives based on scientific community priorities and NASA Announcement of Opportunity. 2) Understand how science requirements lead to the design of instrumentation. 3) Understand practical aspects of mission development. Same as ASTR 5780.
  • ASEN 5940 - Engineering Research Internship
    Primary Instructor - Spring 2024
    Grants credit to foreign visiting graduate students for conducting research within the Aerospace Engineering Sciences department. Credits can be transferred to the student's home institution. CU-Boulder students may also receive credit for conducting research outside of the university, either overseas or in the US.
  • ASEN 6028 - Graduate Projects II
    Primary Instructor - Spring 2018 / Fall 2018 / Spring 2019 / Fall 2019 / Spring 2020 / Fall 2020 / Spring 2021 / Fall 2021 / Spring 2022
    Exposes MS and PhD students to leadership positions in project management and systems engineering while working a complex aerospace engineering project as part of a project team. The project team may perform some or all of the following project activities during this second semester of the two-semester course sequence: requirements definition, design and design review, build, test, and verification. Recommended prerequisite: ASEN 4138 or ASEN 5148 or ASEN 5018 or ASEN 5158 or instructor consent required.
