Welcome to the NIML

The Neurophysiological Imaging and Modeling Laboratory (NIML) at The University of Idaho Department of Biological Engineering is led by Dr. Bryn Martin. Our aim is to conduct clinical translational research that enhances human health and well being for the millions of people affected by CNS disorders. We develop and apply advanced MR imaging and computational modeling techniques to investigate the pathophysiology of CNS disorders from a hydrodynamic and biomechanical perspective and develop related medical technologies.

The NIML seeks highly motivated and critical-thinking students who wish to participate in a dynamic multi-disciplinary research team that makes new discoveries about CNS disorders using state-of-the-art medical imaging and modeling techniques.  We are seeking motivated students for the fall 2015 semester at the University of Idaho, Department of Biological Engineering.

Research

The NIML's research focuses on 1. Intrathecal drug and gene vector delivery, 2. Hydrocephalus and Chiari malformation, 3. Medical Devices and Technology and 4. Neurodegenerative disorders (Figure 4). We conduct in vivo, in vitro and in silico experiments to investigate these four areas.

What is neurohydrodynamics?

Click here for a presentation with background information on neurohydrodynamics.

Neurohydrodynamics is a division of neural engineering that investigates the hydrodynamics of the neurological system in health and disease. It applies engineering principles and design concepts to neural engineering to help close the gap between fluid mechanics and neurosurgical and neurological medicine. Neurohydrodynamics combines fluid mechanics principles with neuroscience to help improve neurological disorder healthcare in terms of medical diagnosis, monitoring, and therapy.
