Career
Prior to joining NTU, Professor Mortimer was Head of the School of Earth and
Environment at the University of Leeds. He joined Leeds as a postdoc in 1994 and
worked his way up to Lecturer (2000), Senior Lecturer (2006), and then Professor
of Environmental Geochemistry (2012). Professor Mortimer holds a BSc (first-class
honours) in Mining Geology from Imperial College, a PhD in Iron Biogeochemistry
from the University of Reading and a Postgraduate Certificate in Learning and
Teaching in Higher Education from the University of Leeds.
Research
Professor Mortimer is an environmental geochemist interested in biogeochemical
processes in sediments and their impact on water quality. His research spans a
wide range of different problems and environments but the common theme is the
use of innovative high resolution sampling and laboratory microcosm techniques.
Ongoing / recent research includes:

Phosphorus delivery to the oceans via dust

Phosphorus dynamics in rivers and wetlands

Sulfur and metal cycling in peat bogs

The role of bed sediments in controlling in-stream nutrient concentrations
in rivers

The impact of river chemistry and suspended sediment on natural ecology
and invading populations

The complexities of cycling of N, Mn, Fe and S in marine, estuarine, and
freshwater sediments and wetlands

The impact of climate change on the dynamics of sediment redox and
biogeochemical processes

Biogeochemistry of contaminant metals (chromium, uranium, technetium,
lead, zinc, copper)

Use of biogeochemistry to remediate nutrient and metal pollution in
contaminated environments

The use of DET and DGT gel technology to make innovative measurements
of the biogeochemistry of aquatic sediments.
