Harald Barsnes is a research group leader at both the Proteomics Unit (PROBE) at the Department of Biomedicine and at the Computational Biology Unit (CBU) at the Department of Informatics.

The main focus of the group is the development of user-friendly open source bioinformatics tools that enable and empower researchers to analyze and share their own data. For more information about the group see www.cbu.uib.no/barsnes.

Barsnes obtained his PhD from the Department of Informatics at the University of Bergen in 2010, with a focus on bioinformatics and proteomics. Since then he worked at the Proteomics Unit at the Department of Biomedicine, first as a senior engineer and later as a Postdoc funded by the Research Council of Norway. He then worked as a researcher at the Department of Clinical Science as part of the Ræder lab, until starting his own research group in 2016 funded by the Bergen Research Foundation and the Research Council of Norway. The research has resulted in numerous publications and a long list of freely available software, including PeptideShakerSearchGUI and PRIDE Converter.

Barsnes has also been a guest editor in PROTEOMICS and has co-authored a Wiley text book called Computational and Statistical Methods for Protein Quantification by Mass Spectrometry. In 2015 he received the prestigious Meltzer Award for Excellent Young Researchers at the University of Bergen, and in 2016 he was awarded a recruitment fellowship from the Bergen Research Foundation.

When not working, you will most likely find him hiking in the mountains. For more details, please see: https://peakbook.org/hbar.
