Connecting biomedical data, robust machine learning, and engineering to advance reproducible healthcare research.


Salam, and welcome. I am a bioengineering researcher with a BSc (Hons.) and MSc in Electrical Engineering from Qatar University. My work brings together medical image computing, physiological signal processing, wearable sensing, biospectroscopy, and computational biomechanics.

I develop and evaluate computational methods for heterogeneous biomedical data, with particular interests in multimodal learning, foundation-model adaptation, domain generalization, and rigorous validation. My research spans data and experimental pipeline development, model design, clinical collaborations, and open research dissemination.

This is a map of recurring research methods and priorities, not a single deployed clinical system.

Current research directions

  • Multiphase liver CT: liver-guided segmentation and complementary-phase evidence fusion for robust liver-tumor analysis.
  • Multimodal diabetic-foot assessment: anatomical alignment and fusion of RGB and thermal images for clinically relevant evaluation.
  • Portable 3D biomechanics: integrating smart-insole measurements and movement kinematics for force, moment, and center-of-pressure estimation.
  • Cross-device microbial spectroscopy: SERS standardization and generalizable classification across acquisition conditions.
