Biography

I develop methods that turn complex data into meaningful insights, combining applied data analysis, statistics and machine learning to address questions with practical impact. As a postdoctoral researcher at the Epidemiology, Biostatistics and Prevention Institute (EBPI) at the University of Zurich, I apply large language models and statistical techniques to patient narratives, free-text responses and structured survey data from health research projects, including the Swiss Multiple Sclerosis Registry. My work explores how these complementary sources can help us understand patients’ experiences, identify patterns and predict future events in their disease journeys.

My broader research interests span computational linguistics, information retrieval and data-driven assessment. During my doctoral research, I investigated how machine learning and data science can help assess competencies across different contexts, using digital interactions to capture skills and real-world problem-solving. Across these areas, I am interested in connecting technical methods with meaningful questions and making the results useful beyond the analysis itself.

I have lived and worked in different countries, which has given me a global outlook and a broad perspective. Experiencing different cultures and ways of working has made me more adaptable, creative, and curious, always ready to take on new challenges and solve problems in different ways.

Outside of work, I love cooking, baking, and travelling. I enjoy cross-stitching, reading, and occasionally going for a hike. I am also into puzzles and board games, and on top of that, I collect ducks.

Research

Main project

SpHeRe: exploring health narratives

I developed SpHeRe, a browser-based system for linked exploratory analysis of health-related free text. It brings sentiment and emotion analysis, topic modelling and PII anonymisation into one workflow, helping researchers explore patient narratives and interview transcripts through interactive visualisations and downloadable reports. SpHeRe supports English, German, French and Italian.

Patient narratives and future events

I turn patient-authored narratives into structured, ordered life events and develop research models to predict future events in patients' disease journeys. This work combines language technologies with sequence modelling to explore how experiences unfold over time.

Patient similarity and virtual twins

I investigate how patient narratives and structured registry data can be combined to identify people with similar experiences and disease characteristics, and examine how these similarities relate to health-related quality of life.

Work in progress

Exploring the potential of virtual twins for persons with multiple sclerosis: an empirical analysis

From patient-authored narratives to ordered life events in multiple sclerosis

Awards and recognition

Award for the contribution of women pursuing doctoral studies in the area of computer science in Spain
Awardee of the Accesit in the SCIE-ZONTA-SNGULAR awards. Its main objective is to recognize the outstanding contributions of women who are currently pursuing a doctoral program in computer science. In addition, it seeks to encourage their start in a research career and create references for new generations, thus contributing to reducing the gender gap in the field of computing in Spain.
Competitive scholarship to pursue MSc studies in Data Science

Academic service

Teaching - Digital Health in Practice
I teach students how to work with and combine different types of health data, including structured self-reports, speech and free-text narratives. I present SpHeRe and demonstrate how to explore health narratives through keyword, sentiment and emotion analysis, and interpret the results alongside other health measurements.
