A.-Javier Aller

Universidad de León, Spain

A.-Javier Aller received his M.S. degree in chemistry from the University of Valladolid. In 1981, he finished his Ph.D. thesis under the direction of Professor Jose Luis Bernal and received his degree with the greatest honors from the University of Valladolid. After a period of four years working in the P/M industry, in 1984, he joined the Department of Biochemistry and Molecular Biology (Area of Analytical Chemistry) of the University of León as an Assistant Professor. Later in 1987, he became Lecturer in analytical chemistry in the same department, while in 2003 he became Professor in analytical chemistry in the Department of Applied Chemistry and Physics in the University of León. In 1985, he was a visiting researcher at the University of Aberdeen (Scotland) and next became Head of the Applied Spectroscopy Group at the University of León. Most of his research focuses on the development of analytical methodologies based on various spectrometric techniques. Main topics include speciation and solid sample introduction in atomic absorption spectrometry. Related interests deal with the nature of interference mechanisms and their consequences on atomization processes in a graphite atomizer. One of the most exciting findings from his work on atomization processes has been its impact on theoretically involved fundamental aspects. Other research field is focused on the use of bacterial cells as analytical tools. He has been working from many years with bacterial cells as biosorbents. Some of his findings have evolved from using lyophilized as well as living bacterial cells. This evolution in the uptake tool used has permitted to increase selectivity of the uptake process making possible the achievement of speciation studies in last term. Another trend was to replace monoelemental detection by a multidetection system. Professor Aller is also heading a research group dealing with the preparation and characterisation of nanomaterials.
