Rod Greder, who earned a doctorate in genetics, spent the first 15 years of his career working in research and marketing for the likes of Pioneer and Cargill.
"My mother always told me I should be a teacher," said Greder, who loved to learn and also harbored a yearn to educate.
That took him to the University of Minnesota, Augsburg and Metro State to teach marketing and management.
At 59, Greder works part time for the U extension service, with small farmers, integrating his love of plant science, environment and teaching.
And it was teaching that also inspired, started nearly a decade ago, an entrepreneurial foray into educational technology.
It has consumed years of Greder's time-and-treasure; yielding promise and recognition, but no payoff so far.
Greder is the founder-owner of Awear Technologies and its ConfiBoost Eyewear prototype for students with ADHD and other reading comprehension and learning challenges. It uses a probe, an electrode connected to the glasses, on the forehead and detects micro-electrical signal changes in the brain when attention diminishes. That causes the ConfiBoost lenses to darken. And prompts the student to refocus attention.
Greder and other educators know too well how many students drift while reading or listening to lecture.
