Biography:

Tibebu G. Ayalew is a postdoctoral researcher interested in solar, heliospheric, and space plasma physics. He completed his Ph.D. in space physics from the University of Oulu, Finland, in 2019. His Ph.D. thesis was focused on observational solar physics, especially the structure and distribution of the solar photospheric magnetic field and its extension out into the heliosphere. In the thesis, he presented, for the first time, a detailed study of the long-term spatial-temporal evolution of photospheric weak-field shifts (also called weak-field asymmetries).  While at Princeton, he worked on the analysis of solar energetic particles (SEPs) using observations of Integrated Science Investigations of the Sun (IS☉IS) aboard the NASA Parker Solar Probe (PSP) mission and hydrogen energetic neutral atoms (ENAs) using observations from the Interstellar Boundary Explorer (IBEX). He was also a member of the Interstellar Mapping and Acceleration Probe (IMAP) mission team while at Princeton University.

Tibebu is currently working with Dr. Nicholeen Viall's research team at GSFC in Greenbelt.
