Lecture title Nutrient and metal cycling in the environment 地点: 环境科学与工程学院 B117 时间:2015 年 12 月 11 日 上午 10: 00 Robert Mortimer Name: Robert Mortimer Role: Dean School / Department: College of Arts and Science, School of Animal Rural & Environmental Sciences Staff group(s): Heads of School Nottingham Trent University Telephone: +44 (0)115 848 5219 Email: robert.mortimer@ntu.ac.uk 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.
