I am a PGR based in the School of Earth and Environment at the University of Leeds working with Prof.  Caroline L. Peacock, Dr. Will Homoky, Dr. Christian März and Dr. Bhoopesh Mishra, investigating the marine biogeochemical cycle of nickel. I previously completed my MSci in Geology at Imperial College London. I enjoy reading and hosting book clubs in my spare time.

Project outline

Micronutrient trace metals are delivered to the oceans and end up being deposited into a number of sinks, including marine sediments. For many metals, marine sediments provide the most important sink, and sediment minerals provide the most important sedimentary hosts. In particular iron and manganese oxides are able to scavenge metals from the overlying water column and from sediment pore-waters and lock up metals over long timescales. Over shorter timescales iron and manganese oxides can age and transform, and new research shows that during transformation these minerals can release some of their metal inventory.

My project looks specifically at how the micronutrient Nickel behaves during the sorption and aging, transformation of manganese minerals.
