Chemistry Researcher | Materials & Catalysis Specialist | R&D in Green Chemistry & Waste Valorization

Profile Summary

I am a Chemistry Researcher with a Master’s degree (GPA 3.99/4.00) specializing in Physical Chemistry and Materials Science, with proven expertise in catalyst synthesis, nanomaterials, and waste treatment technologies. My research background includes the development of heterogeneous catalysts (Fe₃O₄, activated carbon, porous materials) for energy and environmental applications, as well as organic synthesis and biomass conversion. With experience as a university lecturer and R&D researcher, I have led projects funded by the Ministry of Education (DIKTI) and delivered publications in nanomaterials, renewable energy, and sustainable chemistry. I am skilled in laboratory synthesis, scale-up, product development, and advanced instrumentation (GC, GC-MS, UV-Vis, FTIR, XRD, SEM-EDX, VSM, GSA, XPS, and XRF). On Kolabtree, I collaborate with industries, startups, and researchers in the fields of green chemistry, product development, and environmental remediation, offering services in scientific consulting, experimental design, technical writing, and data analysis.
