research overview

  • I study plasma physics of the heliosphere, including the solar wind, planetary magnetospheres, and planetary ionospheres. Topics of particular interest include: high frequency plasma waves, wave-particle interactions, solar wind dynamics, natural micro-meteoroids and human-generated debris impacts on spacecraft, and spacecraft charging. To enable these studies and others, I develop scientific instrumentation for spacecraft, focusing on the measurement of electric and magnetic fields as well as on signal processing techniques and hardware. Past and current instrumentation projects include the Electric Fields and Waves (EFW) instrument on the Van Allen Probes mission (studying Earth's radiation belts), the FIELDS instrument on the Magnetospheric Multiscale mission (MMS) (studying magnetic reconnection), the FIELDS instrument on the Parker Solar Probe mission (studying solar wind heating and acceleration), the RAPS instrument on the COUSIN sounding rocket payload (studying ionosphere-thermosphere coupling), and the AETHER instrument on the Geospace Dynamics Constellation (GDC) (studying ionosphere-thermosphere coupling). Instrumentation projects in development will explore the lightning generated whistler waves in low Earth orbit, the debris environment in low Earth orbit, the plasma environment at the lunar surface, and heating of the thermosphere due to plasma motion.

Teaching

courses taught

  • ASEN 5440 - Mission Design and Development for Space Sciences
    Primary Instructor - Fall 2023
    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.
  • ASTR 1030 - Accelerated Introductory Astronomy 1
    Primary Instructor - Fall 2020 / Fall 2021 / Fall 2024
    Covers principles of modern astronomy summarizing our present knowledge about the Earth, Sun, moon, planets and origin of life. Requires nighttime observation sessions at Sommers-Bausch Observatory. Required in ASTR major/minor. Like ASTR 1000 and 1010, but taught at a higher intellectual level, including a significant amount of quantitative analysis. Degree credit not granted for this course and ASTR 1000 or ASTR 1010.
  • ASTR 2020 - Space Astronomy and Exploration
    Primary Instructor - Spring 2024
    Covers physical principles of performing astronomy from space for science and exploration. The basic design of launch vehicles and spacecraft, orbital dynamics, and instruments will be described in the context of specific space missions (e.g. Hubble Telescope, Mars rovers) as well as prospects for future space observatories in orbit and on the Moon.
  • ASTR 3400 - Research Methods in Astronomy
    Primary Instructor - Fall 2022
    Introduces research methods in astronomy and engages students in an active research project. The research projects will vary and may include astronomical observations, data analysis, scientific programming, theoretical models and statistical inference. As part of their research, students will read scientific papers, attend local seminars and prepare oral and written research proposals and reports. Elective for ASTR majors.
  • ASTR 3760 - Solar and Space Physics
    Primary Instructor - Spring 2020
    Explores the physical processes linking the Sun and planets, emphasizing solar radiative and particulate variability and the response of planetary atmospheres and magnetospheres. Topics include the solar dynamo, solar wind, coronal mass ejections, cosmic ray modulation, magnetospheres, aurora, the space environment, and climate variability. Recommended prerequisite: PHYS 3310. Elective for APS major and minor.
