I am a senior data scientist specializing in healthcare at NTT DATA in Barcelona. I currently focus on developing predictive analytics modules for a clinical trials platform. Additionally, I have implemented a machine learning-powered dashboard to help social care workers anticipate institucionalization in elderly individuals. I also participated in the SmartNation AI Hackathon in Belgium, focusing on structuring free-text clinical data using large language models.
My journey into data science began in an unconventional way. Initially studying to become a pharmacist, my curiosity steered me toward structural bioinformatics, statistics, and software development. This shift ultimately led me to pursue a Ph.D. in bioinformatics. Throughout my doctoral work, I explored the impact of aging on the transcriptome of Caenorhabditis elegans, employing various techniques such as graph analysis, bayesian time-series modeling, machine learning, and generalized linear models.
During my career, I also applied machine learning to predict adverse chemotherapy responses utilizing genetic markers, performed kinetic metabolic modeling, and carried out pharmacokinetics simulations.
Aside from my professional pursuits, I have a passion for languages. I am fluent in French, Portuguese, English, Spanish, and Catalan, and can also hold a conversation in Occitan and Russian.
