My main focus during my undergraduate years was on geomorphology, the study of the surface of our planet and in my case specifically sand dunes and dust sources. For my master thesis projects, I collected and analyzed various mineral dust samples from different locations to study mineralogy, abundance, and locality of these dust samples. As a part of my Ph.D. research, I am involved in studying the characterization of mineral dust particles using spectroscopy and X-ray diffraction. To aim this, I operate different scientific instruments including ASD (Analytical Spectral Devices), and FTIR (Fourier transform Infrared) laboratory spectrometers as well as XRD (X-ray diffraction) instruments. For my current project, the research objective is to focus on gathering information and mineral dust samples to find and understand patterns in the interactions between atmospheric radiation and mineral dust to improve our understanding of scattering and absorption and to model the heating and cooling pattern of Earth.

Research interests

I work on spectral properties of dust minerals through laboratory analysis such as ASD, FTIR, and XRD to identify the mineralogy of dust particles. That helps to derive optical constant for dust aerosols of the various mixture. All those data help to calculate "the alteration of climate caused by atmospheric dust" known as radiative forcing.
