RESEARCH INTERESTS

  • Nuclear reactions important for astrophysical processes: Slow (s-process nucleosynthesis) and fast neutron capture (r-process) reactions. I am highly specialized in the study of radiative capture (e.g., (α,γ) and (p,γ)) and (α,n) reactions, which act as important neutron sources for the s-process nucleosynthesis.
  • Machine Learning Applications in Nuclear Data Analysis: Utilizing machine learning algorithms for nuclear data analysis (e.g., neutron spectrum unfolding using convolutional neural networks) and understanding nuclear structure.
  • Low Energy Nuclear Spectroscopy: Conducting precise and detailed low-energy nuclear spectroscopy using gamma-ray and neutron detectors. Designing and executing accelerator-based experiments for the measurement of nuclear resonances. Performing R-matrix and Hauser-Feshbach analyses for obtaining cross-sections of astrophysically important nuclear reactions.
  • Nuclear Structure: α-clustering in light nuclei, nuclear levels of compound nuclei formed in the radiative capture and (α,n) reactions.
