how does science reconcile the material workings of the brain with human consciousness?

It doesn't yet. Also emergentism somehow...maybe.

its a emergent property of the nuerochemical processes in the brain

just like bloodflow is an emergent property of the processes of the heart beating.

is this to imply that what we see as "awareness" exists in some capacity at all physical levels? otherwise, where does it come from?

No it implies the opposite. That awareness is in fact something that only manifests at a particular level.

Explaining Phenomenal consciousness away as "just an emergent phenomena" misses that there seems to be more than just function emerging. Water has properties not found in a single H2O molecule, but water properties emerging from H2O molecules together with the rest of the environment is something that at least in theory can be fully reducible. This is not the case with phenomenal experience.

The brain is a very complicated collection of physical particles, interacting in a complex ways that causes you to behave in complex ways. But that should be all that those particles are doing: behaving. Yet that doesn't seem to be the case. You can correlate emotions with a certain area in the brain and say, when these neurons fire in this and this way with this intensity, that's emotion X. You can have a very complex functional understanding of how emotion X is caused and how it affects behavior. But with all that, it still doesn't tell us anything about what it is like to experience emotion X; it completely ignores the qualitative aspect. Consciousness is the only thing in the universe where asking how something functions doesn't seem to be able to give us any conceivable answers to the question of why it feels like something phenomenally from the inside. I think that highlights a big gap between explaining how something functions, and explaining experience. From this gap, we can infer that the frameworks of science clearly misses something here in terms of the structure/format of the explanation. Going by what science tells us about the world, this phenomenal experience should not be there, we should all be philosophical zombies without phenomenal experience, but we aren't.

You think of it like being depth. Depth is nothing by it's own. Depth only happens when you have a volume.
Consciousness is what happens when the brain works. It is a byproduct. The invention of words made consciousness even broader.

Biosemiotics

This is just so terribly wrong and uninformative
