Dedicated to the captivating field of planetary geology, my research is focused on terrestrial impact craters, particularly on the Ramgarh crater in Rajasthan, India. My work is centred on a thorough examination of the morphology of the crater, since there is an enduring curiosity among geologists regarding the crater’s morphology. Utilizing radar data and implementing the advanced microwave remote sensing technique, Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR), I intensely studied the subsidence associated with the Ramgarh crater’s structure over time. Furthermore, my research extends to the quantification of erosion rate, offering a comprehensive temporal perspective on the geological evolution of Ramgarh crater from its formation to the present-day. Through this extensive exploration, I aim to contribute valuable insights to the broader understanding of terrestrial impact crater’s geological history.

My doctoral research emerged after the discovery of a crypto-tephra layer in an onshore sedimentary basin within Kerala. The glass shards collected from dug well sections near Changanasseri Town were dispersed from Mount Toba in Sumatra during the Youngest Toba Tuff (YTT) event. This fact gave me insights to pursue research to establish a marker horizon to correlate the Late Pleistocene sediments which are far beyond the detection limit of radiocarbon dating. I aim to find more sites in Kerala, where the YTT materials are preserved in subsurface sections. This can be achieved by collecting core samples, studying the sub-samples under the microscope and characterization of the suspected materials using sophisticated analytical techniques. Finally, the horizon with YTT materials can be validated by geochronological methods. Once the YTT marker horizon is established, it can be utilized as a proxy in future studies aiming to decipher the Late Pleistocene paleoenvironment of the Kerala coast.

My doctoral research revolves around understanding the spallation expanse of terrestrial impact craters by leveraging lunar craters as proxies. On Earth, factors like rock mixing and climatic changes make it challenging to determine the true extent of spallation. The Moon, being geologically inactive, preserves a pristine record of impact craters, making it an ideal model. I'm developing correlation models to analyze the relationship between projectile size, ejecta size variation, and the distance between distal and proximal ejecta locations. Using lunar data, I aim to establish size-to-distance trends and explore transportation processes influencing ejecta. The research seeks to refine methodologies for studying impact events on Earth and other planetary bodies.

My doctoral research is an ambitious exploration of Mars' ancient climate and the presence of water on its surface and subsurface. Focused on impact craters like Gale, Jazero, and Hellas Basin, I employ high-resolution images and cutting-edge 2D hydraulic modeling with HEC-RAS software to investigate fluvial deposits. This study aims to unveil compelling evidence of water during Mars' early, warmer, and wetter climate, marking a pioneering use of hydraulic modeling on the red planet.
Beyond examining fluvial deposits, I delve into aeolian and ejecta features, unraveling the aftermath of mega-flooding events that shaped Martian landscapes with deltas, mega-ripples, and anti-dunes. The innovative 2D hydraulic modeling becomes a virtual river, allowing simulation and understanding of water flow patterns. This research is poised to be the first to provide robust evidence of water on Mars, promising to reshape our understanding of Mars' climatic evolution and the role of water in its historical landscape.

My research is focused on the global mapping of lunar minerals and volatiles for studying the mineral-volatile interactions on lunar surface utilizing the state-of-art Near Infrared (NIR) spectrometers of Chandrayaan-2 & Chandrayaan-1 missions. Volatiles on Moon is shown to have distinct time of the day, soil maturity and latitudinal dependencies but the influence of lunar minerals in volatile distribution is still unknown. Establishing a correlation between volatiles and minerals is important to understand influence of minerals in volatile distribution and the lunar volatile cycle. To differentiate and map lunar OH and H2O, I primarily rely on Chandrayaan-2's Imaging Infrared Spectrometer (IIRS), offering an extended spectral coverage up to 5 µm. Unlike previous efforts limiting spectral range to 2.5 µm, I employ the full IIRS spectral range with thermal correction to explore shortwave infrared spectral responses of minerals. The mineral abundance estimations in combination with the geologic context will be useful for finding correlations with the OH/H2O absorption band strength and for identifying potential water sources focusing mainly over higher latitudes (±60°) of Moon.

My doctoral research focuses on unraveling the enigma surrounding the Ulindakonda Agglomerate within the Archean Gadwal Greenstone Belt. This geological formation, characterized by its Archean age and significant dimensions, has posed intriguing questions about its origin, composition, and temporal aspects. Through detailed fieldwork, petrographic and geochemical analyses, and the examination of recent drilling data, I aim to decipher the nature and mode of formation of this enigmatic agglomerate. Additionally, I seek to explore its potential correlation with the initiation of the Proterozoic Cuddapah Basin, examining the role of the giant Archean Caldera eruption and its implications for the broader understanding of basin development. This research not only contributes to our understanding of the Archean geodynamic evolution in the Gadwal Greenstone Belt but also sheds light on the significant geological processes that may have shaped the western margin of the Proterozoic Cuddapah Basin.
My doctoral research dives deep into the impactful landslides that gripped Kerala during the intense 2018 monsoon, bringing with it a staggering 140% excess rainfall.

My doctoral research dives deep into the impactful landslides that gripped Kerala during the intense 2018 monsoon, bringing with it a staggering 140% excess rainfall. Picture this: I meticulously crafted a detailed landslide inventory, totaling a whopping 4728 events, by refining existing datasets through the lens of Google Earth imagery validation. This inventory serves as the cornerstone for unraveling the factors that set the stage for these landslides, and one significant player in the drama is land use land cover (LULC).
I'm shedding light on the pivotal role of LULC changes, especially in densely vegetated areas, forested plantations, and urbanized zones, as catalysts for the landslide dance. To get a dynamic perspective, I simulated long run-out debris flows using the Rapid Mass Movement Simulation (RAMMS) tool. The results unveiled distinct pathways based on the magnitude of released volumes, providing a vivid picture of how these events unfolded. But that's not all – I've tapped into the power of radar remote sensing techniques, specifically Persistent Scatterer Interferometry (PSI), for landslide monitoring. This not only aids in susceptibility mapping but also guides the prioritization of mitigation efforts. The crux of my research? It underscores the urgency of developing a comprehensive risk mapping strategy for informed developmental planning in regions prone to landslides.
