Group Members & Alumni

Our group has trained researchers who now hold faculty positions, lead government laboratory programs, and work at the frontier of aerospace. Here is where they came from — and where they went.

Current Researchers

Meers Oppenheim
Principal Investigator

Meers Oppenheim

Professor of Astronomy & Associate Director, CSP

Ph.D. Cornell 1995. Research spans ionospheric turbulence, solar chromosphere, and meteor plasma physics. CEDAR Prize Lecturer 2016. Over 80 refereed publications.

Yakov Dimant
Senior Research Scientist

Yakov Dimant

BU Center for Space Physics

Leading theorist in the group. Fundamental contributions to the theory of E-region instabilities, meteor plasma formation and diffusion, anomalous conductivities, and the thermal Farley–Buneman instability in the solar chromosphere. Co-author on over 40 group publications.

Alexander Green
Postdoctoral Researcher

Alexander Green

Astronomy Ph.D., BU (~2026)

Dissertation on ionospheric physics and meteor trail echoes. First-authored papers in GRL (2025) and Frontiers (2025). Built massively parallel PIC and EM wave propagation codes within the group. Currently continuing as a postdoc here.

Save Koontaweepunya
PhD Student

Save Koontaweepunya

Expected graduation ~2028

Researching non-Maxwellian ion distributions in the equatorial and auroral electrojets (Koontaweepunya, Dimant & Oppenheim, Frontiers 2024). Working on 3D kinetic simulations of the high-latitude electrojet.
