Professor, BME

(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

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.

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

BHASKAR LAB

Dhananjay Bhaskar

Assistant Professor, BME

MISSION

We are a computational lab with interests in machine learning, mechanistic modeling, and AI for Science. Our goal is to understand how structure and dynamics give rise to function in complex systems – from molecules and cells to circuits and behavior.

We develop methods that capture the shape, symmetry, and flow of biological processes in high-dimensional, often noisy data. To do this, we design algorithms in geometric deep learning, topological data analysis, and manifold learning, that relate the ‘shape’ of data to its underlying biology. We tackle challenging inverse problems – using data to infer the cellular and molecular interactions or neural connectivity that drive observable behavior. Ultimately, our aim is to create biologically informed, interpretable, AI models that not only explain how systems work but also drive translational impact through engineering and precision medicine.

WHAT WE’RE UP TO

  • Identifying in-silico biomarkers of neurological and psychiatric conditions using multimodal neural and behavioral data
  • Integrating and translating across brain imaging modalities
  • Learning high-order interactions and network dynamics from large-scale brain activity recordings
  • Building brain encoding and decoding models to understand how information is represented, transformed, and recalled
  • Designing new learning algorithms that emulate neuronal dynamics, plasticity, and self-organization for more biologically grounded AI

NERV LAB

Jonathan Soucy

Assistant Professor, BME

MISSION

We engineer neural tissues and interfaces to restore vision in degenerative retinal diseases.
The Neural Engineering for Restoring Vision (NERV) lab studies how the visual system develops, remodels, and can be repaired after injury or disease. We engineer ex vivo and stem cell-derived models of the retina, optic nerve, and retinorecipient targets in the brain to uncover the principles of neuroplasticity. By combining electrophysiology, tissue engineering, and cell transplantation, we are developing tools to study how transplanted neurons integrate into host circuits and using transplantation itself as a strategy to restore vision. Our goal is to translate fundamental discoveries into therapies that promote remodeling, repair, and recovery in the visual system.

WHAT WE’RE UP TO

  • Organoid and organ-chip models – Engineering retinal tissues to study neural circuit formation and donor-host integration
  • Neuron transplantation therapies – Developing strategies to restore vision lost to glaucoma and other optic neuropathies
  • Activity modulation tools – Using chemogenetic and optogenetic approaches to tune donor and host neuron activity and study neuroplasticity
  • High-density electrophysiology – Applying advanced recordings to map connectivity and assess the recovery of vision after transplantation
