Based on its analysis of citation records, the international media and information concern Thomson Reuters has named Professor Ferenc Krausz, who holds a Chair in Experimental Physics at LMU and a Director of the Max Planck Institute for Quantum Optics in Garching, as one of its Citation Laureates 2015. The accolade recognizes those researchers in the fields of medicine, chemistry, physics and economics whose publications have been cited most often in leading journals, and are therefore seen as highly influential by their peers.

Ferenc Krausz is regarded as the founder of the field of Attosecond Physics. He was the first physicist to generate and characterize pulses of laser light that last for a few hundred attoseconds (1 attosecond = 10-18 second). With the aid of these ultrashort pulses he and his colleagues have carried out ground-breaking studies on the dynamics of electron motions in atoms, which have led to ground-breaking insights in atomic and condensed-matter physics. Krausz has also developed a novel laser technique which makes use of innovatively crafted mirrors to control the waveform of such pulses with unprecedented precision. The high-intensity electromagnetic fields associated with femtosecond pulses (1 fs = 10-15 s) are comparable in strength to those that bind electrons within atoms, and can measurably affect their behavior. Consequently, this laser-based technology provides a new window into the workings of the microcosmos. In addition, ultrashort laser pulses also have a range of eminently practical applications in various fields, including biomedicine.

Seven ‘Highly Cited Researchers’ at LMU
According to the list of Highly Cited Researchers 2015 issued by Thomson Reuters, seven other LMU scientists are among the most influential researchers worldwide in their fields. The compilation is based on a global assessment of citation records for research papers published in the fields of Natural, Social and Biomedical Sciences between 2003 and 2013. The number of citations garnered by a given author is regarded as a reliable indicator of the overall impact of his or her work.

In addition to Ferenc Krausz as a Citation Laureate, two other LMU physicists, experimental physicist Professor Immanuel Bloch and Nobel Laureate Professor Theodor Hänsch, are on the latest list of highly cited researchers. Indeed, these three members of LMU’s Physics Faculty account for half of the six physicists based in Germany whose names appear on the list, which comprises 119 researchers in all.

The other LMU faculty members listed in the report are Professors Martin Parniske and Niels Dingemanse (Faculty of Biology), Professor Lars Diening (Mathematics Institute), psychiatrist Professor Hans-Jürgen Möller and epidemiologist Professor Heinz-Erich Wichmann. Niels Dingemanse and Martin Parniske are among the 22 German researchers listed in the field of Plant and Animal Science, which comprises a total of 172 scientists. Lars Diening is one of only three Germans cited in a list that includes a total of 99 mathematicians. Professor Hans-Jürgen Möller (retired) is one of three German researchers (in a worldwide total of 110) who are among the most cited authors in the field of Psychiatry/Psychology. Heinz-Erich Wichmann, Professor of Epidemiology at LMU (retired), and erstwhile Director Institute of the Institute of Epidemiology at the Helmholtz Center Munich, is among the most influential German researchers in the area of Molecular Biology & Genetics. The ranking in this field includes a total of 198 authors.

Only the most highly cited papers count
The complete compilation of Highly Cited Researchers 2015 comprises approximately 3100 scientists and scholars in 21 disciplines. The citation records on which the analysis is based are drawn from the Web of Science, which monitors how often research papers are cited by scientists other than their authors. The number of citations garnered by an individual researcher serves as a measure of the quality and impact of that person’s scientific impact in the eyes of his or her colleagues. Furthermore, only the top 1% of the most highly cited papers in a given field for a given year were considered during compilation of the report.
