High Performance Cybernetics
Chris specializes in the development of advanced cybernetic controller technologies designed to enhance sightless and tactical navigation, spatial and situational awareness, rapid information exchange, dynamic hazard detection and avoidance, and self-defense.
With an extensive academic background, Christopher served as a faculty lecturer in the departments of Psychology and Neuroscience at The Ohio State University. He also conducted post-doctoral research on Human perception and computational vision during his tenure. Additionally, Christopher imparted his knowledge as a lecturer in the department of Psychology at the esteemed University of Minnesota. His educational qualifications include a Doctor of Philosophy in Cognitive and Biological Psychology, with a focus on Mathematical Modeling and Statistics, as well as a Bachelor of Arts in Cognitive and Biological Psychology from the University of Minnesota.
Beyond his academic pursuits, Christopher dedicates his time and energy to safeguarding our environment and natural resources. He is the founder and operator of The Golden Lake Preservation Society, a testament to his compassion and dedication to Nature and Humanity. Furthermore, Christopher cherishes the support of his beloved family and friends, having cultivated meaningful connections with over three dozen remarkable roommates during his travels and stays around the Globe. Currently, he resides at Pine Cove with his Life partner, caring for an organic farm, encompassing pine and hardwood forests, while also providing a loving home to orphaned pets. As a versatile individual, Chris also expresses his creativity through music and art for Global Tactile.
