I am deeply interested in research involving energy and environmental
sustainability with a focus on energy generation and storage, biofuel, renewable energy, and sustainable material research.
Research Experience
Graduate Research:
Studying radial phase segregation and lithium volatilization on an all-solid-state battery electrolyte known as LLZO (Lithium Lanthanum Zirconium Oxide). Check out my new paper where we explored this phenomenon on an Al-doped LLZO. Future work will involve exploring the LZO pyrochlore distribution across two other dopants (Nb and Ta) and the impact of the segregation on the electrolyte conductivity.
Figure:A schematic showing mechanisms that create lithium concentration gradients in LLZO during sintering. As illustrated in the proposed reaction pathway below, lithium volatilizes from the material into the gas phase (as Li2O) and is replaced by Li+ diffusing from the sample center to the sample edge. Li+ depletion at the sample center transforms c-LLZO into LZO, preventing Li+ back-diffusion and creating a LZO gradient that diminishes from the sample center to the edge.
Using Second Harmonic Generation (SHG) / non-linear optical methods to study adsorption kinetics on high-temperature energy conversion devices. Currently studying the effect of biasing a gold monocrystal to alter the oxygen adsorption rate on the surface.
Undergraduate Research: I studied the density wave-pattern speed of a simulation of barred-spiral galaxy M83. The research involved the generation of density and iso-contour velocity plots from simulation data of M83 and a comparison of the plots with CO emission of the galaxy.
Then, the Tremaine Weinberg Method was applied to data cubes produced from the density and iso-contour velocity plots of the simulated galaxy to determine its pattern speed. More information can be obtained from the following research paper.

BIO
I like to spend my quality time reading research papers, coding on Python, painting, playing guitar, writing poetry, and taking photos using my DSLR.
Currently, I am enjoying playing basketball although I suck at three-pointers. I was born and raised in Bangladesh.
