15/11/2023 - Invited talk at the Universität Kassel

Last week I was invited by Prof. Werner Seiler to travel to Kassel (Hessen, Germany). I gave a talk about "Studying biosystems robustness, uncertainty, and other properties through symmetry analysis" at the research training group Multiscale Clocks. Lots of interesting discussions -- and ideas for future collaborations!

06/10/2023 - New paper

"Controllability and accessibility analysis of nonlinear biosystems" has been published at Computer Methods and Programs in Biomedicine: doi:10.1016/j.cmpb.2023.107837. In this paper we provide implementations of algorithms for testing nonlinear accessibility and controllability, and apply them to several systems of biomedical interest.

28/08/2023 - SELDOMpy released

SELDOMpy is a python version of SELDOM, a method for building predictive signalling models. SELDOMpy has been developed by Luis Prado López under the supervision of David Henriques and Alejandro F. Villaverde. It is available in PyPI and GitHub.

21/07/2023 - PhD thesis defense

Today, Gemma Massonis Feixas has successfully defended her PhD thesis. Entitled "Contributions to mechanistic modelling in systems biology: identifiability, symmetries and uncertainty quantification", it was co-supervised by Julio R. Banga and Alejandro F. Villaverde. Congratulations, Dr. Massonis!

20/07/2023 - Participation in CINBIO's 6th Annual Meeting

Today, Sandra and Xabier are presenting posters at the CINBIO 6AM, which is the Annual Meeting of the Centre for Biomedical Research at the Universidade de Vigo.

10/07/2023 - Talk at SIAM AG23

This week, Alejandro F Villaverde is attending the SIAM conference in Algebraic Geometry ( SIAM AG23) in Eindhoven, to give a talk entitled "How Often Do We Encounter Locally-But-Not-Globally-Identifiable Parameters in Systems Biology, and Why?".

22/06/2023 - New paper

"On the origins and rarity of locally but not globally identifiable parameters in biological modeling" has been accepted at IEEE Access: doi:10.1109/ACCESS.2023.3288998.
