I am a particle physicist working at the CMS experiment at CERN. My current research focuses on searches for Supersymmetry and Dark Matter in the CMS detector. I am also involved in the new CMS MTD project. I am employed as a Ramon y Cajal researcher at the Institute of Physics of Cantabria (IFCA).

In charge of coordinating the certification, data quality monitoring and validation of the Muon POG. This implies organizing the DQM tools, and also assessing the quality of the software releases and the data collected by the experiment.
In charge of coordinating the stop, sbottom and stau searches withing the CMS SUSY group.
In charge of coordinating the CMS Supersymmetry trigger and Monte Carlo strategy for the Run 2 data-taking starting in 2015. Both strategies were designed and implemented and are nowadays the baseline for all the CMS Supersymmetry searches.
I led a group of post-docs and students from several universities during 3 years. After an intense process of internal review I presented the final results to the collaboration in October 2014. This search was acknowledged as the most interesting indication of New Physics seen by CMS during the Run 1 of the LHC. Nowadays I continue leading this search in the context of Run 2.
I initiated in 2012 an innovative analysis to measure the energy scale of the b-jets using a novel technique invented by me to estimate the effect of the neutrinos. The results were very competitive and were presented in the TOP conference in 2014 as one of the highlights from CMS. I was the contact and only contributor of this analysis. Publication is in preparation.
During my thesis I developed novel methods to align the CMS muon system using muons. I was selected as contact person of the muon alignment group and responsible of the geometry databases. The geometries used in the start-up of the LHC were calculated and maintained by me. In recognition CMS awarded me in 2010 with the “Outstanding Achievment Award”. University of Cantabria also awarded me with the prize to the best PhD thesis in science.

This publication shows a search for sleptons using the 2016 dataset collected by the CMS experiment. This analysis was conducted by Leonora Versterbacka for her PhD thesis with my help and supervision.
This publication targets a search for DM produced in association of a top quark pair. I contributed to the dilepton channel on this analysis and the analysis was part of the thesis of Juan Ferrero Garcia.
This publication contains a search for SUSY in models with both strong and electroweak production of sparticles. I was the contact person of this analysis in CMS.
This publication contains a summary of procedures used to calibrate the jets. The paper includes several sub-analysis. I was the author of the calculation of flavor dependent corrections for b-jets.
This publication contains a summary of the CMS Trigger performance during Run 1. As convener of the SUSY trigger group I was the editor of the SUSY triggers section.
This publication replicates and improves the dilepton search performed during Run I with 2015 data at 13 TeV. A new likelihood discriminator was developed in order to reject the ttbar background. Some of these results were also part of a Master Thesis supervised by me.
This publication contains the most interesting indication of New Physics found by CMS. The work was performed as a collaboration among ETHZ, UCSD, and RWTH. I led the effort and presented the final results to the CMS collaboration in 2014. The PhD. student I supervised published these results in his thesis.
This search was developed by a collaboration including ETH, UCSD, UCSB and Fermilab. I co-led with two other ETH Post-docs the development of a novel method called Jet-Z Balance to predict the amount of Drell-Yan background. I was selected to present these results in ICHEP12.
This analysis was developed by the ETH group where I collaborated with other Post-docs and students. I contributed actively to the development of the ~@~\lost-lepton method~@~] to pree dict the amount of W+jets and top pair production backgrounds.
In this paper the techniques and the results of the first alignment of the CMS muon system with muon tracks are presented. I developed the techniques (with the exception of the Beam-Halo alignment) and results that provided the first aligned geometries of the muon system of CMS.
This paper provides a technical description of CMS, summarizing the CMS Technical Design Report that contains the foundations of the detector. I made major contributions in the set-up of the procedures to align the muon system. (An extended version was included in an 8-page contribution in the CMS TDR).
