Thank you for entering the GRASS (Grup de Recerca en Anàlisi eStadística de la Supervivència) website. The information you will find on this page is not up to date. Currently, this group has broken up into several more multidisciplinary research groups that are listed below along with the contact information:



Research Group in Biostatistics and Bioinformatics (GRBIO). Research group with expertise in in Biostatistics and Bioinformatics, mainly Survival Analysis, Clinical Trials and Biostatistical Methods for Integrative Analysis of Omics Data. Contact: Lupe Gómez () 


Research Group in Bioinformatics and Medical Statistics. It is an interdisciplinary group that includes life sciences, statistics and bioinformatics in a Systems Biology framework, with special emphasis on the study of the genetic basis of complex diseases. Contact: Malu Calle ()


Biostatistics Unit (UBiostat). The Biostatistics Unit has the mission of generating knowledge that can help improve health. Statistical methods are essential for designing studies, analyzing data and interpreting results. We work with researchers to turn their data into useful information to advance research. The main objective of the UBiostat is to strengthen the efficiency and quality of research groups at the IRBLleida. Contact: Montse Rué ( 


Advanced Stochastic Modelling. Part of the Servei d'Estadística Aplicada (SEA) of the UAB. The goal of the group is to analyse and solve practical multidisciplinary problems through stochastic and statistical modelling tools, and apply the ideas and results obtained in the theoretical investigation to problems arising from a wide range of areas. Contact: Anna Espinal (
