Personal Statement

My laboratory develops noninvasive Neuroscience Engineered user-interface technologies that aim to solve societal accessibility and mobility problems for disadvantaged populations — with a particular emphasis on addressing problems stemming from Blindness and Visual Impairment (BVI).

My training and professional work at the University of Minnesota comprised several distinctively focused academic and technical disciplines. As an Instructional Technology Fellow, I taught scientific programming and statistical methods to graduate students and faculty. As Lab Director for our College’s Scientific Apparatus Fabrication Laboratory, I guided a team of graduate students developing research apparatuses for the Departments of Psychology, Radiology, and Neuroscience, and The Institute of Child Development. Our 2,000 square foot lab employed a variety of prototyping methods, including: electronic circuit design and prototyping, metal fabrication, turning and machining, plastic molding, CAD, and 3D CNC milling. I developed and mastered many design techniques while creating dozens of complex and sophisticated devices for fMRI, psychophysics, psychometrics, clinical and social psychology, and child development research at the University. My designs and devices included computer electronics, electro-mechanical devices, software development, and optical devices for vision, neuroscience, and behavioral-developmental research. Those professional works persisted for the majority of my tenure as a research assistant, technology fellow, and lab technician at The University of Minnesota.

In addition to my distinctive design and engineering background, I was trained by leading translational and interdisciplinary research scientists and professors, who engaged me with practical engineering problems addressing humanitarian needs. My academic mentorships and collaborations (see publications below) have ultimately inspired me to further develop devices for blind and visually impaired people, and ultimately to found Global Tactile, LLC. I continue to work alongside my lifelong professional career colleagues and friends, while continuing to develop and commercialize important and promising technologies that bring more freedom and improve quality of life for the blind and visually impaired community and beyond.

After graduating from the University of Minnesota, I transitioned from NIH-funded translational research to NSF-funded discovery research at The Ohio State University. At OSU, I learned a complementary set of sophisticated mathematics that have strengthened my cognitive and computational neuroscience knowledge— to address deeper and more nuanced issues related to the human sensory and perception-action systems. Finally, as a faculty lecturer at OSU, I taught hundreds of students in the areas of Sensation & Perception and Cognitive Neuroscience, which completed the basic knowledge I sought to deeply understand neural and cognitive processes—fundamental to my company’s product designs, and ultimate success as a contributor to those who need adaptive and accessibility solutions.

I was a lecturer at two major public state universities (UMN & OSU), where I taught a variety of courses that were important to my development as a Neuroscience Engineer. At Minnesota, teaching Major Project gave me the opportunity to teach students long term project planning. At OSU, Cognitive Neuroscience solidified my understanding of how the brain is structured to adapt and use reliable information. And finally, teaching Sensation and Perception introduced additional fundamental knowledge of the human sensory system at deep level of understanding. All of these experiences inspired my biomedical innovations and product designs that are necessary to develop my company’s technologies and scientific innovations.

Contributions to Science

Low Vision, Blind Navigation, & Spatial Perception

These contributions addressed problems associated with low vision and blindness. Of particular interest was my manuscript titled: Variability in Stepping Direction Explains the Veering Behavior of Blind Walkers, which seeded our working solution for veering.
