PhD Summary

I am researching the rapid emplacement of lava flows of the Deccan Large Igneous Province in western India. My project focuses on the Thakurvadi formation and Giant Phenocryst Basalts (GPBs) that are associated with climate perturbations before the mass extinction event from 66 Ma, marking the CretaceousPaleogene (KPB) boundary. Through this project I aim to understand the mechanisms associated with the Deccan trap eruptions and identify its implications for late Cretaceous climate change. 

Previous activity

Prior to the PhD, I graduated with a degree in BSc (Hons) Geology and Physical Geography followed by a Masters by Research (MRes) in a volcanology and GIS themed project titled Modelling lahars at Merapi (Indonesia) and Rainier (USA) volcanoes using Titan2D and LaharZ computer models. During my Undergraduate and masters study, I also interned as a research assistant for the European Marine Observation and Data network (EMODnet), where I created GIS maps, showing coastal vulnerability levels across the European coastline. 

Why did you choose doctoral research?

I enjoy the process of learning new information while also contributing to existing knowledge through research. Conducting research as part of my coursework and internships solidified my passion for scientific learning – particularly geology and volcanology which motivated me to undertake doctoral research. 

Why did you choose CENTA?

CENTA studentships offer a variety of training courses that enable students to develop practical and technical skills which can applied to various aspects of careers in both academia and industry I am confident that the skills I will develop through my studentship with CENTA alongside training provided by my host institution will make me a well-rounded researcher and help me in effectively navigating my career in industry or academia. 

Future plans

By the end of my PhD, I hope to have utilized the resources available through CENTA and my host institution to build skills and networks which would direct me towards a career in volcanological and geological research. In the future, I am keen on continuing with research in volcanology and Earth Sciences and am open to doing so through academia or industry.
