Selected contributions include;·• Processed garnet-type ceramics, Li7La3(Zr, Hf)2O12 and Li5La3(Nb, Ta)2O12, as potential electrolytes for Li-ion batteries through the conventional solid-state reaction.• Fabricated and sintered the pellets of the ceramics for characterization and measurement.• Employed X-ray powder diffraction to analyze the crystal structure of ceramics and scanning electron microscopy with electron dispersive spectroscopy to study their microstructure.• Studied the phase transformation of Li7La3(Zr 0.9Hf0.1)2O12 from tetragonal to cubic phase with High-Temperature X-ray (HTXRD) and Electrochemical Impedance Spectroscopy (EIS). • Synthesized cubic Li5La3(NbTa)2O12 garnet and investigated crystal structure and ionic conductivity as a function of sintering temperature.• Fabricated symmetric cell (Li/LLNTO/Li) with Li5La3Nb0.2Ta1.8O12 garnet ceramics and studied cyclicstability as a solid-state electrolyte. • Performed analysis for electrochemical impedance spectroscopy data related to Li7-stuff and Li5- stuff garnet solid-state electrolytes using a Python package, impedance.py.

As a Research Assistant, I have been performing various tasks for processing and fabricating materials, including operating automated and semi-automated equipment. Major roles are like:. Fabricating oxide glass with the conventional melting and quenching method to establish a co-relation between structure and electrical properties.· Determining electrical conductivity of ceramics, glass, and glass-ceramics by the van der Pauw four-probe method.· Operating X-ray Fluorescence in conducting chemical analysis of the glass and glass ceramics as well as using X-ray powder diffraction, scanned electron microscopy, and differential thermal analysis in characterizing and identifying glass and glass ceramics.

I lectured physics lab courses for engineering students as well as tutored undergraduate students on Physics I and II courses while heading the faculty and leading academic activities. I did develop and implement course materials as well as manage the science laboratory and organize educational fairs. I designed and facilitated the whole syllabus, including preparing lessons, determining instructional objectives and administering assignments and assessment tests.
