Projects

Photovoltaic Retinal Prosthesis

Optoelectronic system for restoration of sight to the blind, based on patterned electrical stimulation of retinal neurons using subretinal photovoltaic array.

 
 
 

Laser-Tissue Interactions

Mechanisms of interaction of pulsed lasers with biological cells and tissues including pulsed hyperthermia, photocoagulation, explosive vaporization, photodissociation, and multiphoton ionization. Development of ophthalmic applications of these interactions.

 
 
 

retinal rewiring

Retinal Plasticity

Migration and rewiring of retinal neurons after selective ablation of pigmented eptithelium and photoreceptors. Models of retinal degeneration and restoration of retinal structure and function.

 
 
 

vasculature

Electronic Control of Vasculature

Mechanisms and applications of pulsed electrical stimulation to control the extent of contriction and perfusion of blood vessels.
