My primary research focus lies in exploring the semantic and referential meaning within speech, particularly within narrative structures. I specialize in studying these aspects in clinical populations afflicted with schizophrenia and related psychotic disorders. My objective is to unravel the functioning of diverse linguistic mechanisms in these individuals, while also drawing comparisons with neurotypical counterparts. To accomplish this, I employ Natural Language Processing (NLP) tools and Machine Learning. I predominantly program in Python.

I was born in Valparaíso and I studied Industrial Engineering and Economics at the University of Chile, graduating in 2013. After that, I worked as a Research Analyst doing economic and data analysis for several years. In 2018, I moved to Barcelona to pursue a Master's degree in Theoretical and Applied Linguistics at the Universitat Pompeu Fabra. I did my PhD under the supervision of Professor Wolfram Hinzen, where I worked on referential and semantic meaning to assess clinical symptoms in Schizophrenia Spectrum Disorders (SSD).

Interests

I'm passionate about learning new languages (currently studying Russian, Georgian and Japanese). In my free time, I read, write poetry and take long walks or hike. I also love experimenting with new recipes in the kitchen.
