Specialisation

Study of planetary surface mineralogy and geology using remote sensing multi- and hyper-spectral data

Research

Areas of interest and plan:

Applied spectroscopy and planetary surface mineralogy (using spectral data-- Lunar M3, IIRS, Ceres VIR, Venus VIRTIS, Mars CRISM data, and using remote sensing software and python and shell scripting)
Experimental spectroscopy and mineral sciences understanding the basic physics and chemistry of mineral spectral features, especially the Electronic and Vibrational processes (using FTIR, Raman, XRD)
Experimental mineralogy and crystal chemistry of aqueous minerals, especially the phyllosilicates, carbonates, sulphates (using XRD, Raman, SEM/EDS)

Few questions of interest:

Water (OH/H2O) on Moon: What is the physical and chemical state-- structural or molecular or ice/frost or other? How wet or dry is the Moon? What it implies in terms of lunar evolution and the solar system context?
Missing mantle material of Moon: Is mantle material exposed in the South Pole Aitken basin? Is it olivine-rich or Mg-rich orthopyroxene? What it implies toward the geologic evolution of so-called differentiated planetary bodies?
Asteroid Ceres -- formed in the inner or outer solar system? Is this question solely depend on the detection of ammoniated-phyllosilicates because of 3.1 micron feature? If so, what is the uncertainty in NH4+ feature detection? And, what are the physical and chemical rationality for the origin either in the inner or outer solar system? What it implies in the solar system / ocean worlds / exo-planetary exploration?
Venus surface and geology -- active or not? What are the surface/sub-surface processes and links to volcanism and tectonism? How the surface science is coupled with atmosphere? How the surface mineralogy and processes could tell about the Venusian geologic evolution and what it implies in the solar-system / exoplanetary / Ocean worlds exploration and habitability?
Carbonate conundrum on Mars -- Why carbonates are missed on Mars-- is it observational issue or geologic issue by nature that is not understood? How the enrichment in sulphates is linked? What it implies in the Martian geology and atmosphere and in the the solar system context?
Understanding crystal chemistry and quantum mineralogy of aqueous minerals, especially phyllosilicates, carbonates and sulphates enriched in OH/H2O and salts -- What is the physical and chemical state of the cationic and anioinic complex? What does the earliest formed aqueous minerals in the solar system imply in terms of the physical and chemical state?

Research projects and opportunities:
