香港六合彩

I am a Lecturer in Environmental Change and an environmental geochemist. I have expertise in reconstructing and monitoring climatic, environmental, and anthropogenic drivers of aquatic ecosystem change over timescales ranging from decadal to hundreds of thousands of years.

The main focus of my research and teaching is the use of lake sediments to reconstruct past environments by comparing geochemical approaches with ecological techniques and proxy data with the instrumental record to provide robust reconstructions. I have applied these techniques globally, including across Europe, Asia, the Middle East and the Arctic.听

Research Interests

I apply quantitative field and lab-based methods to address a broad range of pressing issues in environmental change, particularly the impact on aquatic ecosystems of the feedback between human activities, climate, biogeochemical cycles, and ecological processes.

Specifically, my research uses traditional (e.g. Mg/Ca, stable isotopes of oxygen and carbon) and novel (P/Ca, clumped isotopes) geochemical proxies and contamination indicators (heavy metals, spheroidal carbonaceous particles) in natural archives such as biogenic carbonates (ostracods, foraminifera, and corals) and sediments in lake, marine, and riverine environments globally. In combination with species assemblage data and instrumental records, I am interested in applying these techniques across aquatic ecosystems and my work has included:

1. The alongside sediment geochemistry and grain size to reconstruct storm surges in European coastal lakes over the last 200 years.
2. of heavy metal concentrations of riverine suspended material in tropical Asian deltas.
3. to reconstruct sea ice cover and freshening of the Canadian Arctic Ocean over the last two millennia.
4. Establishing new, more robust, methods to reconstruct nutrient enrichment of shallow lakes.听

Impact

My research has strong ecosystem management implications, which is reflected in my sustained collaboration with conservation organisations, including the , , and . Where appropriate, these organisations have co-produced research, and it has had direct benefits to local stakeholders. For example, my research on the effects of agricultural drainage and storm surges on lakes in the is being used as scientific evidence by the Broads Authority and in the implementation of new land drainage pumps. During my postdoctoral work at the University of Nottingham, I was seconded to in the Flood and Water team for one month to complete a rapid evidence review, creating a database of evidence to be used by Defra, the Environment Agency and Natural England.听

My at Aarhus University aimed to provide a new ostracod-derived geochemical method, which I compared to more 鈥榯raditional鈥� palaeoecology techniques (e.g. diatom transfer functions and macrofossil presence-absence), for reconstructing shallow-lake enrichment. The impact of this work will be the establishment of direct quantitative baseline eutrophication restoration targets under the for the first time.听

Whilst working on the at the University of Nottingham, my research also had strong policy implications. I was co-lead of the Community Science working group, which involved a large interdisciplinary effort to assess the environmental, economic, and cultural importance of small water bodies. The research was selected as a UKRI Interdisciplinary Research Excellence case study. As part of these interdisciplinary efforts, I am joint lead author on a pioneering journal article that was the first in the field of . In addition, my findings on 听were highlighted in a UKRI Development Impact case study. This research on heavy metal pollution has also contributed to an article soon to be submitted to Environment Magazine, the official press of the .听

In addition, I have promoted the accessibility of science and higher education through numerous activities, including 香港六合彩 Widening Participation, , and as a peer-reviewer for , a diamond open-access journal dedicated to the publication of sixth form and undergraduate geographical research.听
