Product Development Engineer
With decades of experience in product development, it’s easy to see what makes Marvin an asset to the J-Band team. His resume includes companies such as Koch Materials, Road Science LLC, and SemMaterials. He has worked on emulsions, polymer-modified asphalt formulation, product development, upscaling production for commercialization, and much more. He has a BS in Mechanical Engineering from Rose-Hulman Institute of Technology and is even the author of several papers.
But there is another thing that makes Marvin an asset to our customers: he understands what it’s like to work out in the field.
As Marvin puts it, “My brother was 12 years older than me. He started working at 21 in asphalt marketing. I grew up around asphalt talk and worked in the lab for two summers while in college. I’ve always been in the technical group, but it took years for me to realize that most technical people has limited exposure to the marketing side. I think it helped give me a unique perspective around customer focus and recognizing customer needs. The marketing exposure helped me to focus on realistic solutions to customer needs and issues” Along with lab evaluations and field data, he is able to leverage this understanding in his work as a product development engineer. All these things come together to help him optimize J-Band.
When he’s not in the lab, Marvin enjoys classic cars (including his 1970 Mach 1 Mustang from college) and competitive marksmanship.
