About me

I am a PhD student in the Intelligent Systems Program at the University of Pittsburgh. I am currently working in the Pitt Health and Explainable AI Research Laboratory (Pitt HexAI) under the guidance of Dr. Ahmad Tafti. My research interests include:

  • Machine learning & deep Learning
  • Generative AI and synthetic data
  • Explainable AI
  • Few-Shot learning
  • Applications of computer vision for medical imaging

Presently, my focus revolves around enhancing the explainability, addressing biases, and ensuring fairness in AI algorithms used for segmenting knee and hip bony anatomy. Additionally, I’m involved in implementing these advancements in cloud-based applications.
