[1] His PhD was carried out at Harvard University and ETH Zurich with Steven A. Benner and culminated in the award of a Dr. sc.

He completed his habilitation in 1998 ('DNA Recognition by Eukaryotic Transcriptional Regulators')[2] and then joined the University of Birmingham, first as a Senior Lecturer and then Professor of Chemical Biology.

Since 2005 he has been a Distinguished Research Professor at Cardiff University and in 2017 was appointed Pro Vice-Chancellor and Head of College of Physical Sciences and Engineering.

By exploiting chemical, biophysical, enzymological and molecular biology techniques, he has made contributions towards understanding enzymatic mechanisms.

[4] Allemann's work on hydrogen transfer catalysing enzymes including dihydrofolate reductase has led to deep new insights into the contributions from quantum mechanical tunnelling and protein dynamics to the enormous rate accelerations typical of Nature’s catalysts.
