About Me

(Big Sur, Pacific Coast Highway, California)

I am currently a postdoctoral researcher working with Jonathan Pritchard at the Department of Human Genetics at the University of Chicago. My research focuses on developing novel computational methods for understanding gene regulation by integrating new experimental assays (ChIP-seq, DNase-seq, FAIRE, and others) and genome annotation (sequence, conservation, gene structure). In collaboration with colleagues at the University of Chicago, I developed CENTIPEDE a novel probabilistic framework to predict tissue-specific regulatory sites for DNA-binding proteins using DNase-seq footprinting (Pique-Regi et al. 2011 Genome Res). Subsequently, we used DNase-seq to measure chromatin accessibility in 70 Yoruba lymphoblastoid cell lines (LCLs), for which genome-wide genotypes and estimates of gene expression levels based on RNA-seq are also available. This work represents provides direct results supporting a molecular mechanism for a large fraction of genetic determinants of gene expression (Degner, Pai, Pique-Regi, et al., 2012 Nature). 

Previously, I obtained my Telecommunications Engineering degree from the Universitat Politecnica de Catalunya, Barcelona, Spain in 2002.  My master thesis proposed a new videoconference compression algorithm that used Adaptive Principal Component Analysis approach (advisor: Lluis Torres ). I did my Ph.D. in Electrical Engineering at the University of Southern California, Los Angeles, CA in 2009 (advisor Antonio Ortega). My Ph.D. work focused on developing new Bioinformatics methods to analyze microarray data using Signal Processing techniques. I collaborated with  Children's Hospital of Los Angeles (co-advisor: Shahab Asgharzadeh) to develop new methods for: i) building a tumor prognosis classifier for neuroblastoma cancer using gene expression microarrays (DLDA and BDLDA), ii) detecting copy number alterations in cancer samples and variation in human populations (GADA).
