Yukitoshi NishimuraToshi Nishimura is a research associate professor at Boston University. He works on magnetosphere-ionosphere coupling across scales using all-sky imaging, radars, and satellite observations. Key research contributions include the substorm pre-onset aroral sequence, pulsating aurora driving by chorus waves, day-night coupling by flow channels, and localized transients throughout the system. He has received the James B. Macelwane Medal from American Geophysical Union in 2016. He has chaired multi-scale ionosphere-thermosphere coupling sessions at CEDAR workshop and AGU in 2018.
