• Conducted PhD research on surface modification of metalloproteins and hemin on nanostructured materials for electrochemical sensor fabrication. • Developed sustainable and low-toxicity nanomaterial systems using TiO2 nanotubes, carbon nanotubes, Halloysite nanoclay, metal oxide interfaces, and hybrid nanocomposite structures. • Designed and optimized functional material interfaces to improve stability, reduce nanoparticle aggregation, preserve active sites, and support long-term sensor performance. • Appl

• Worked on a funded applied research project focused on sustainable nanomaterials for sensing and analytical applications. • Planned and executed laboratory experiments involving nanomaterial synthesis, characterization, and performance validation. • Operated analytical instruments and methods including SEM, TGA, HPLC, UV-Vis spectroscopy, fluorescence spectroscopy, and cyclic voltammetry. • Improved reproducibility through structured experimental methods, lab documentation, data analysis, and interpretati

• Supported research planning, documentation, qualitative and quantitative data analysis, and grant application activities. • Monitored project timelines and supported laboratory coordination in a collaborative academic research environment.

• Performed quality inspections of manufactured products to support compliance with industrial standards and process reliability. • Inspected incoming and outgoing products, documented results, and identified quality issues at an early stage. • Gained practical exposure to industrial quality control, process monitoring, and manufacturing-related documentation.

Master’s project: Diffusion properties of Natural Rubber-SBR blends and solvent interaction behavior, with focus on polymer material behavior, chemical exposure effects, and aging-related property changes.

Bachelor’s project: Photocatalytic degradation of textile dyes using titanium dioxide and silver nanoparticles.
