Lab Groups

Research within WITNe is conducted across labs that communicate openly. Our engineering researchers, medical researchers and medical practitioners work closely together, sharing knowledge, resources, people, collaborator networks, animal models, grant support, access to industry contacts, training opportunities and increased visibility.

WILLIAMS LAB

Justin Williams

Vilas Distinguished Achievement Professor

Department of Biomedical Engineering and Department of Neurological Surgery

(a-g) Different µECoG array geometries designed to interface differently with biological immune responses of the brain and meninges

MISSION

Develop new devices for recording from and stimulating neural tissue that are both safe and durable for long-term implantation, as well as safe for use in humans and animals; plus, validate the use of these new devices in animal models and human patients.

WHAT WE’RE UP TO 

  • Developing new devices for recording from and stimulating neural tissue
  • Designing these devices to be both durable for long-term implantation and safe for use in humans and animals
  • Using these technologies in a variety of situations, from use in a basic physiology lab recording from single neurons, to clinical settings where people with motor disabilities might benefit from a brain-computer interface or other neural prosthetic communication device

MISSION

Translate next generation neuromodulation therapies to highjack the nervous system to treat circuit dysfunction and deliver biomolecules to target areas with unprecedented precision.

WHAT WE’RE UP TO 

  • Acute and longitudinal benchtop characterization of new minimally invasive neural interfaces based on proven experience supporting FDA regulatory submissions
  • The application of cutting-edge optical tools in rodents to better understand and design clinical neuromodulation interfaces
  • Comprehensively instrumented swine model to refine new neuromodulation strategies at human anatomical scale in order to assess effects and side effects
  • Detailed functional and post-mortem anatomical evaluation across animal and human experimental models to reduce the time to translation of new concepts

SUMINSKI/LAKE LAB

Aaron Suminski

Senior Scientist, Department of Neurological Surgery

Wendell Lake

Assistant Professor, Department of Neurological Surgery

Mechanisms of Vagus Nerve Stimulation in Translatable Large Animal Model
Optimizing Cortical Response Specificity to Trigeminal Stimulation
Network Effects of STN Deep Brain Stimulation

MISSION

Understand how neuromodulation therapies regulate neural activity both in close proximity to the stimulating electrodes and in neural circuits receiving projections from the site of stimulation.

WHAT WE’RE UP TO 

  • Optimizing patient outcomes following implantation of neuromodulation therapies using advance imaging techniques and electrophysiology
  • Investigating the mechanisms of action for neuromodulation therapies using experimental models across the translational spectrum from basic science in rodent models to clinically translatable research in large animal models and human patients

These frames demonstrate collagen fibers encapsulating indwelling neural devices. Panel A and B quantify and visualize, respectively, that collagen fibers are only observed on the surface of the device, not in the surrounding parenchyma. Panel C shows fibers encircling the device as well as extending along the length of it.

MISSION

Develop advanced optics and computational techniques for imaging and experimentally manipulating living specimens

WHAT WE’RE UP TO

  • Computational optics research
  • Imaging the cellular microenvironment of wound healing models
  • Developing software tools such as FIIJI for 3D visualization analysis
