Research statement<\/strong><\/p>\n\n\n\n

I\u2019m a geochronologist by training, with expertise in trapped charge dating techniques of luminescence and electron spin resonance (ESR). I use these techniques not only as a classical dating method for the Quaternary, but also as tool for exploring novel applications in geomorphology. My research primarily combines aspects of sedimentology, sediment geochemistry and geochronology to reconstruct and constrain the timing, rates and processes of landscape-climate interaction over Quaternary timescales, with a strong focus on developing applications of trapped charge dating methods in the study of earth surface processes.<\/p>\n\n\n\n

Over the past years, a major focus of my research has been on developing and validating the application of different luminescence signals and ESR-resolvable defect centres in the quartz mineral as a proxy for provenance, with the ultimate goal of understanding \u2018source\u2019 to \u2018sink\u2019 transport within sedimentary systems. At the ICE group in UNIL, I aim to extend my research scope and work towards the development and application of quartz ESR thermochronometry – a novel approach to extract the thermal history of quartz to better constrain later stage rock cooling histories, and gain insight into landscape evolution over late Quaternary timescales.<\/p>\n\n\n\n

Brief Biography<\/strong><\/p>\n\n\n\n

I did my B.Sc. and M.Sc. in Chemistry from the University of Delhi, India (2009-2014). Following which, I pursued a M.Sc. in Archaeological Sciences at the University of Oxford, U.K. (2014-15). It was here that I developed an interest in trapped charge dating. After a short research stint in the Luminescence laboratory at the Physical Research Laboratory, India (2015-16), I moved to Germany for my PhD. I completed my PhD in Geology at the Max Plank Institute for Chemistry (MPIC) Mainz, Germany in 2021. Post PhD, I was a postdoctoral Fellow at the University of Tuebingen, Germany (2021-22) and then, in the European Research Council (ERC) project – PROGRESS at Babes-Bolyai University, Romania (2022-24).<\/p>\n\n\n\n
