Borislava Toleva, PhD, is an academic researcher and data science practitioner with a strong foundation in both Economics and Statistics. She earned her bachelor’s degree in Economics and a master’s degree in Statistics, Financial Econometrics, and Actuarial Science at Sofia University, where she later defended her PhD degree in Data Science. Her research focuses on advancing predictive algorithms, optimizing their performance, and extending their applications beyond traditional domains. She is also interested in applying big data techniques to small and complex datasets, offering innovative alternatives to classical econometric approaches. By integrating methods from Statistics, Econometrics, and Machine Learning, she demonstrates how Data Science can uncover hidden insights in Economics and related fields, ultimately providing researchers with more interpretable and actionable results.
