Fields of interest

I am a geologist always enthusiastic to make the world a safer place to live in and making its resouces equally available for all for generations to come.

My research interest includes application of petrology, geochemistry and diffusion modelling (geospeedometry) to address the still open questions of how Earth became the only known habitable rocky planet covered by oceans and an oxygenated atmosphere. I have been interested to understand the evolution of plate tectonics and its evidence preserved within the continental rock record.

During my Ph.D. in Germany, I have had the opportunity to visit localities in western Australia, eastern Canada and India which hosts some of the oldest rocks of our planet. I have always been an enthusiastic field geologist as such excursions helps us to understand the different geologic features associated together in spatial resolution which to me is an integral part of the research before looking into intricate details or carry out high resolution studies in laboratories. I have been using a combination of extensive field-work and sampling, along with the expertise in petrology, advanced geochemical and isotopic techniques (Lu-Hf garnet geochronology, U-Pb zircon geochronology) and also application of diffusion chronometry on rock samples from SW Greenland and Coorg Block, India to understand Early Earth’s deep crustal processes in a global scale.

At UCPH, I am a part of the 'Early Earth Research Group' led by Associate Prof. Kristoffer Szilas and am currently involved in understanding the mechanism of corundum formation in the mafic rocks from the Ujaraggsuit complex in SW Greenland using various analytical and modelling approaches. Constraining the timing and the factors leading to corundum formation is challenging but the information is crucial for understanding the thermochemical conditions required for their growth within metamorphic systems, which in turn can provide insight into their relationship with the prevalent tectonics. In addition, their study can help us better develop strategies for gem exploration. Therefore, I am interested in the formation of some of the world's oldest rubies ever reported from Greenland and hence might provide valuable insight into the early Earth geodynamic scenario.
