Bachelor in Astronomy
  • Thesis: Formation of binary systems Black Hole-Star: the case of Gaia BH1 and Gaia BH2.
    Analyzed population synthesis simulations (SEVN code) for Gaia BH1/BH2, providing strong evidence that a dynamical formation scenario, rather than isolated evolution, is probable origin for these systems.

Projects

Galaxy Classification using CNN

  • Built and benchmarked CNNs for morphological classification on the GalaxyZoo 2 dataset.
  • Optimized hyperparameters with Optuna, achieving RMSE of ≃ 0.06.
  • Validated model scalability for large-scale astronomical surveys.

Data analysis of hierarchical mergers of black holes simulations

  • Analyzed hierarchical binary BH merger simulations across diverse star clusters (Python, Pandas).
  • Investigated cluster conditions in BH evolution by comparing mass, spin, and merger generation distributions.
  • Applied Random Forest to identify key drivers of higher-generation BH formation.
  • Quantified clusters’ influence on merger remnant retention and high mass BH populations detected via GWs.

Distributed analysis of Cord-19 dataset

  • Executed large-scale text analysis (≃ 200k papers) using Dask for distributed computation.
  • Developed parallel word-count algorithm and generated NLP embeddings to compute cosine similarity.
  • Benchmarked cluster performance, analyzing scalability and overhead to improve efficiency at scale.

Learning the topology of a Bayesian Network using the K2 algorithm

  • Implemented the K2 Bayesian Network structure-learning algorithm in R.
  • Developed automated node order search methods using brute force and simulated annealing.
  • Benchmarked and validated algorithm performance against the standard bnstruct R library.

Carrom Tournament Bot

  • Developed and deployed an MVP Telegram bot (Python, Docker, MySQL) for automated tournament management and data analysis, enabling reproducible deployment and robust statistics computation.
