Consulting services for the generation, control, and application of light
Andrew Bierman
Founder and Principal
I am a research scientist and electrical engineer with over 30 years of experience in lighting. Lighting plays an important, yet largely unrecognized role in our modern-day lives; it is how we see the environment around us, it’s in the technology that brings us information, and it grows our food and keeps us healthy. My specialties are the application of technology to further scientific discoveries about light and solving technical problems to being new and old lighting ideas to reality. Namreiba was formed as single-member limited liability company (LLC) registered in New York State to facilitate my contributions to businesses and science.
