    A Comprehensive multiomics approach towards understanding obsessive-compulsive disorder 

    Domènech Salgado, Laura (Date of defense: 2018-12-20)

    To date, very little progress has been made towards elucidating the genetic causes of obsessive-compulsive disorder (OCD). In this project we have performed rare variant association study (RVAS) transcriptomics and ...

    A Comprehensive screening of X-linked and miRNA-driven signatures of positive selection and the role of cis-regulatory elements in the human genome 

    Villegas Mirón, Pablo (Date of defense: 2021-07-19)

    The evolutionary history of the human genome has been shaped by the selection of multiple elements in response to different environmental pressures. The analysis of regulatory adaptations and the particularities of sexual ...

    A Comprehensive study of arithmetic circuits and elliptic curves for efficient and scalable zero-knowledge proof systems 

    Bellés Muñoz, Marta (Date of defense: 2023-10-10)

    In recent years, zero-knowledge proofs have come to play a crucial role in distributed systems where there is no trust between the parties involved. Most popular proof systems are for the NP-complete language of arithmetic ...
