Mazdaq Ghajari talks about cycle helmet testing and the HIPER project
Mazdak GhajariGuestPodcast HostHostIs that right? Is that how you describe yourself?
The background, mechanical engineering, and now my research is very much, uh, focused on biomechanics of traumatic brain injury.
Yeah.
So engineering, brain injury don't seem obvious bedfellows at start, but I guess really important in understanding how injuries happen, the mechanisms that happen in the brain and in the head when, when they happen, and also how we might prevent those injuries from happening in the first place.
I think, um, specifically, uh, talking about traumatic brain injury, it's, it's a type of injury that is caused by mechanical forces, and that is where engineers are relevant because we, we know how to... what are the forces, how we can measure them, how we can even simulate in order to predict-
Mm
So yes, we can, we can actually, um, help bridge between, uh, the initial insult, which can happen in several applications like road traffic, sporting, conflict, and the, the resulting injury, in collaboration with, of course, with neurologists and neurosurgeons.
