The Springer journal Shock Waves has just published the first of a two-part series of thematic issues on blast-induced Traumatic Brain Injury (bTBI). The thematic issue includes an editorial overview of the relevant bounds of the injury threat and a discussion of the outstanding intractable problems in the field of bTBI research, written by guest editors Simon Ouellet (Defence Research and Development Canada Valcartier) and Prof. Oren Petel (Carleton University, Mechanical & Aerospace Engineering). The two-part series provides a snapshot of the current state of research in the field of bTBI from an experimental and computational perspective, and includes contributions from a cross-section of international researchers in academic, industrial, and government-funded research institutions.
