Miranda Marcus, PhD
Polymer Welding Expert
Principal Consultant & Trainer at Mangrove
Miranda Marcus is a recognized authority in polymer welding and plastic joining, bringing together deep technical expertise, academic rigor, and decades of hands-on industry experience. With a PhD in Polymer Engineering from the University of Akron and degrees in Welding Engineering from Ohio State, she has spent over 20 years helping organizations solve their most challenging joining problems.
Her expertise spans ultrasonic, laser, infrared, thermal, vibration, radio frequency, extrusion, hot gas, induction, resistance, and related welding processes. As Principal Engineer at Ohio State CDME/AIMS and through Mangrove, Miranda has trained professional engineers across medical, automotive, defense, packaging, electronics, and consumer products industries.
Technical Leadership in Polymer Welding
Expertise and Specialization
Miranda's work sits at the intersection of materials science, manufacturing engineering, and practical problem-solving. Her specialization in polymer welding means she understands not just how processes work, but why they fail and how to fix them. From ultrasonic horn design to laser transmission parameters, she brings a level of technical depth that comes from years of R&D, consulting, and hands-on troubleshooting across hundreds of projects.
Industry and Training Experience
Having worked with organizations ranging from medical device startups to automotive OEMs and defense contractors, Miranda understands that every industry has its own requirements, standards, and constraints. Her training programs are built around this reality, delivering targeted knowledge that engineers can apply immediately on the production floor. Whether it's a two-hour masterclass or a multi-day in-plant training, participants leave with practical skills backed by solid theory.
Why This Matters for Clients
When you work with Miranda through Mangrove, you're not getting a generic plastics consultant. You're getting someone who has published peer-reviewed research on ultrasonic weld strength prediction, trained hundreds of engineers across multiple continents, and solved welding problems that others couldn't. That combination of academic rigor and real-world pragmatism is what sets Mangrove apart, and it's what makes the difference between a project that struggles and one that succeeds.
