Research Scientist

EU Horizon SynAir-G (Grant No. 101057271)

• Disrupting Noxious Synergies of Indoor Air Pollutants and their Impact in Childhood Health and Wellbeing, using Advanced Intelligent Multisensing and Green Interventions (Grant Agreement No. 101057271).
• Investigation of synergistic interactions between indoor air quality metrics and physiological signals from wearable devices using multivariate and temporal causal models.
• Scientific Coordinator: Prof. Nikos Papadopoulos

Research Scientist

Pfizer CDI — EyeAI Research Project

• Supervised dataset curation, annotation workflows, and quality control for ocular imaging.
• Developed an attention-gated UNet++ architecture for automatic sclera segmentation from smartphone-captured eye images.
• Quantized and deployed the model on-device for real-time smartphone inference (TensorFlow Lite / ONNX).

Research Scientist

Pfizer CDI — Voice-Based Diagnostics (VBD-2)

• Designed and deployed an end-to-end, on-device AI pipeline for continuous, passive respiratory screening with real-time cough detection and disease analysis.
• Processed 10-second tracheal and chest-wall auscultation recordings from the built-in microphone, with percussive noise removal and frequency-spectrum correction to mitigate domain shift across auscultation sites and microphone devices, for asthma and COPD detection.
• Developed a ResNet-34 classifier with a probabilistic voting mechanism for robust, explainable disease identification, plus deep generative models for cough and lung-sound synthesis to address training-data scarcity.

Research Scientist

Pfizer CDI — Voice-Based Diagnostics (VBD-1)

• Cough detection algorithms and abnormal/normal lung sound classifiers deployed for real-time smartphone inference using the built-in microphone.

Research Scientist

University General Hospital of Patras — Dept. of Internal Medicine

• Supervised dataset curation, annotation workflows, and quality control for respiratory infection data (audio and imaging).
• Multimodal deep-learning research combining paired lung sound recordings, chest X-rays, and inflammatory biomarkers to distinguish bacterial vs. viral pneumonia and identify clinically meaningful audio biomarkers.
• Development of mobile and web-based clinical data acquisition tools for in-hospital deployment.
• Clinical collaborator: Prof. Dr. Dimitris Velissaris

Research Scientist (Ocular Biomarkers)

University General Hospital of Patras — Dept. of Internal Medicine
