    Talk Title: Neuro-Gastroenterologic Engineering

    Abstract: The discoordination between the central and autonomic nervous systems is increasingly being identified as playing a key role in affecting neurological, psychiatric, and gastroenterologic problems; the causal role that the enteric nervous system may play in Parkinson's disease serves as an example. However, traditionally, the brain and GI system have been studied scientifically and treated clinically, separately. There is a dearth of approaches to use engineering perspectives to better measure, characterize, and provide actionable insight about the GI system as well as its interplay with the brain. In this talk, we will discuss our recent contributions to address this unmet need. Specifically, we will discuss our recent development of novel methods to assess the GI system with high-resolution multi-electrode surface potential recordings, an approach that non-invasively characterizes propagation velocity and propagation patterns consistent with gastric serosal slow wave myoelectric activity, which had not been accomplished until now. We will also highlight novel applied probability methods to interpret these classes of dynamic multi-channel physiologic datasets, including directed information graphs, a new class of probabilistic graphical models that provides minimal descriptions of causal relationships in multiple time series. To enable the recording of multiple physiologic time series simultaneously and unobtrusively, we will lastly discuss our development of multi-electrode arrays embedded within skin-mounted adhesives for ambulatory monitoring. We will highlight how all of these methods and technologies are being used within the context of neuro-gastroenterologic engineering and how there is transformational potential to improve health, reduce healthcare costs, and advance science.

    Biography: Todd P. Coleman received B.S. degrees in electrical engineering (summa cum laude), as well as computer engineering (summa cum laude) from the University of Michigan.
