In an effort to gain a fuller understand of pain and nociceptors, our lab is involved with a grant to assemble and grow neuron cultures and assess injury-induced changes in gene expressions and protein/metabolite profile in tissue compartments.
​
Under stress conditions neurons will grow and forced through micro-channels to innervate tissue which is normally found in the knee joint.
​
My role in early stage development is to design an embedded microcontroller chamber, or the DRG Dish.
