Fernando Alonso-Fernandez received the MSc/PhD degrees in telecommunications from Universidad Politecnica de Madrid, Spain (2003/2008). Since 2010, he has been with the School of Information Technology (Halmstad University, Sweden) first with a Marie Curie IEF and a Post-Doctoral Fellowship from the Swedish Research Council (both grants obtained simultaneously), and later as recipient of a Project Research Grant for Junior Researchers of the Swedish Research Council. Since 2017, he has been an Associate Professor at Halmstad University (permanent position), and since 2019, he has been an External Collaborator at the University of the Balearic Islands, Spain. 

He has been involved in multiple EU (such as FP6 Biosecure NoE and COST IC1106) and national projects (such as SIDUS-AIR, CAISR, AI.m. 2.0, MIDAS, Diffuse) focused on security and analysis of signals for biometric purposes. He has consistently attracted funding grants as PI on biometrics research from the prestigious and very competitive Swedish Research Council in 2010, 2013, 2017 and 2022 (only one active grant is allowed as PI on a specific research topic, and he has always obtained a new grant in the subsequent call after the previous one ended). He also contributes to teaching on different aspects of Biometrics and Computer Vision at all levels (Bsc, MSc, PhD), and regularly serves as examiner of MSc and PhD theses, both nationally and abroad.  

He has co-authored over 120 international contributions at refereed conferences and journals and several book chapters. He co-chaired ICB2016, the 9th IAPR International Conference on Biometrics. In addition, he is Associate Editor of IEEE T-IFS, Pattern Recognition Letters, and the IEEE Biometrics Council Newsletter. He also contributes as regular reviewer and organizing committee in top venues such as IEEE TIP, TIFS, TBIOM, Image Vis Comput, Pattern Recognition, Information Fusion journals, or ICPR, ICIP, EUSIPCO, IJCB, ISBA conferences.

He is a member of the IEEE, IAPR, and the national contact point for the European Association for Biometrics (EAB). He is also involved in other roles at the EAB, such as co-chairing the EAB-RPC (the annual Research Projects Conference, currently the largest event on research funded by the EU in Biometrics and Identity Management) or being jury member of the of the annual EAB Biometrics Awards (granted to the best PhD theses in Europe on biometrics research).
