Research: Applied Engineering
When we think of brains, we think of neurons. Non-neuronal cells, however, make up more than ten times the population of neurons in the brain. Our research aims to reveal the implications of this huge disparity by determining the principles that govern the roles of non-neuronal brain cells. To date, neural computation remains studied as a purely neuronal process, but that is like trying to solve a puzzle with 10% of the pieces. It will be necessarily insufficient for understanding circuit-level function and dysfunction. Recent results highlight that understanding the role of non-neuronal cells in slowly regulating neural activities could revolutionize our understanding of neural network activity and neurocomputation in neurodegenerative diseases and brain injuries.

Therefore, our lab focuses on elucidating biological structures and biochemical pathways that control physiological function and bidirectional communication between the nervous system and neural interface technology, especially hidden, latent signals (glia, neurovascular coupling, LTP/LDP). We then apply these newly discovered constraints and possibilities into designing novel technologies and treat neurological conditions.
In order to elucidate real-time long-term cellular and molecular tissue interactions to chronically implanted medical devices, we employ in vivo functional electrophysiology, two-photon microscopy, biomaterials, and electrical and optical stimulation techniques. These technologies allow us to advance our understanding of the brain and brain interfaces, as well as create new avenues for diagnosis and treatment of brain pathologies. Ultimately, the goal is to understand how neuronal and non-neuronal cells are integrated in neurocomputation, and understand how to devise targeted intervention strategies for specific neurodegenerative diseases and brain injuries.

Cybernetics is defined as the transdisciplinary approach for exploring regulatory system, their structures, constraints, and possibilities, particularly from biology and man-made technology. Our lab takes on a transdisciplinary approach for exploring glial, vascular, and neural regulatory systems for functional neural network activity in normal, injured, and disease brains. By understanding the structure and function of each regulatory component, it becomes possible to identify constraints of the system, and more importantly, possibilities for treatments and cures.
