Profile Summary

I’m a PhD-trained Mechanical Engineer and Materials Scientist with expertise in molecular simulations, nanomaterials, polymer composites, computational chemistry, and sustainable material design. As the founder and CEO of EcoRue, I lead projects at the intersection of advanced sustainable material design, climate-aligned innovation, sustainable material design, interdisciplinary sustainability strategy, and policy-relevant research. My work spans computational R&D, nanocellulose, high-performance polymers, and environmental consulting. At EcoRue, my expertise lies in designing environmentally responsible, high-performance materials and translating complex research into policy-relevant and scalable solutions I help organizations with scientific writing, data analysis, literature reviews, grant writing, experimental design, and strategic advisory on sustainability and innovation. Having published peer-reviewed research and collaborated internationally, I bring both academic rigor and applied industry insight to client projects.
