Visitors to ALRL

Aberystwyth Luminescence Research Laboratory has had a number of visitors in recent years who have come to undertake joint research with staff of ALRL. These visits both enrich the laboratory and are an important part of the work of ALRL in fostering luminescence research in the UK and around the world.

Visits may range from a few days to a year or more. In general visits of several months to a year are the most productive, and frequently result in joint publications.

Recent visitors include:

Svenja Riedesel

(Institute of Geography, University of Cologne, Germany)

Svenja made excellent use of a short visit in 2016 to make single grain measurements of tsunami deposits from Japan. The work will be presented at the UK Luminescence and ESR dating meeting in Liverpool in 2016.

Dr Xianjiao Ou

(School of Geography and Tourism, Jiaying University, China)

Dr Ou spent almost 12 months at ALRL undertaking research into glacial sediments from the Tibetan Plateau. This work was presented at the International Electron Spin Resonance and Luminescence Dating conference held in Montreal in 2014.

Dr Shugang Kang

(State Key Laboratory of Loess and Quaternary Geology, Institute of Earth Environment, Chinese Academy of Sciences, Xi’an, China)

Dr Kang visited ALRL to undertake measurements of loess related to his long standing research in understanding the dynamics of Quaternary environmental change in China.

Dr Grzegorz Adamiec

(Institute of Physics, Silesian University of Technology, Poland)

Dr Adamiec spent an intensive period of time in ALRL undertaking crucial research into the characteristics of the source trap of the thermally- transferred optically stimulated luminescence signal in quartz. This work was presented at the UK Luminescence meeting in Royal Holloway in 2009.

Dr Bo Li

(Department of Earth Sciences, The University of Hong Kong)

Dr Li spent a period of several months at ALRL using our single grain system designed for analysis of feldpsars (using an IR laser for optical stimulation) to assess whether single grain feldspars could be used for his iIRSL isochron method.

Luminita Preoteasa

Luminita visited ALRL to learn about OSL dating and to apply the method to coastal beach ridges and dunes in the Danube delta. This work has been presented at a number of conferences, including the International Coastal Sedimentology meeting held in Portugal (April 2009).

Dr Jeong-Heon Choi

Dr Jeong-Heon Choi (Korea Basic Science Institute, South Korea)

Dr Choi used a range of methods to understand the properties of volcanically derived from quartz from Kenya in an attempt to improve our ability to date such complex materials

Anni Madsen

(Institute of Geography, University of Copenhagen, Denmark)

As part of her masters programme, Anni visited ALRL and undertook work on a sediment core from a New England salt marsh. Overwash sands found in the core record hurricane strikes, and Anni used luminescence to date these.

Prof Naomi Porat

Dr Naomi Porat(Geological Survey of Israel)

Dr Porat has visited ALRL on a number of occasions. Most recently her work focussed on the development and application of thermally transferred OSL methods. Some of the results from this work were presented at the last LED meeting in Beijing (Sept 2008).

Dr Jin Cheul Kim

Jin Cheul Kim(School of Earth and Environmental Sciences, Seoul National University, South Korea)

Jin has visited ALRL twice, undertaking research work on fine grained samples from the Jeongokri area in South Korea. OSL analysis involved study of samples close to saturation, and thus TT-OSL methods were also developed and applied.
