Bio-Signals Processing &
Rehabilitation Robotics (BSRR) Lab

Welcome to BSRR Lab, where rehabilitation is engineered through biosignals. 

The Bio signals processing & Rehabilitation Robotics (BSRR) Lab is an interdisciplinary research group focused on the acquisition, analysis, and application of human physiological signals for advancing rehabilitation engineering and healthcare technologies. The laboratory is dedicated to bridging the gap between fundamental biomedical signal processing and real-world clinical rehabilitation needs. 

Overview

Our work involves the use of both clinical-grade and advanced research instrumentation to acquire high-fidelity physiological data directly from human participants. These include  

  • Electromyography (EMG) 
  • Electrocardiography (ECG) 
  • Electroencephalography (EEG) 
  • Photoplethysmography (PPG)  
  • Respiratory signals  
  • Pulse measurements 
  • Blood pressure, 
  • Grip force dynamics. 

We aim to capture a comprehensive understanding of human physiological responses under various conditions, particularly in rehabilitation and assistive scenarios. 

A central focus of the lab is the development of robust signal-processing pipelines and intelligent computational frameworks for extracting meaningful features from complex and often noisy biosignals. We employ advanced techniques from digital signal processing, statistical modeling, and machine learning—including deep learning approaches—to interpret physiological data with high accuracy and reliability. These methodologies enable us to identify patterns, assess functional recovery, and derive clinically relevant insights that can support diagnosis, monitoring, and therapeutic interventions. 

Positioned at the intersection of biomedical engineering, applied physiology, and computational intelligence, the BSRR Lab addresses critical challenges in rehabilitation science. Our research is driven by practical and translational questions:

  • How can recovery be quantified more precisely and objectively?
  • How can assistive and rehabilitative devices be controlled in a more intuitive and human-centric manner?
  • How can rehabilitation protocols be adapted dynamically to suit individual patient needs? 

Through this work, we aim to contribute to the development of personalized, data-driven rehabilitation systems that enhance patient outcomes, improve quality of life, and support clinicians in delivering more effective and responsive care. The lab also actively fosters collaboration across disciplines, encouraging innovation at the convergence of engineering, medicine, and human-centered design 

About

The BSRR Lab focuses on biomedical signal processing, brain-computer interfaces, and AI-driven healthcare technologies. Our research involves acquiring and analyzing multi-modal physiological signals such as EEG, ECG, and EMG using both clinical-grade and research-oriented instrumentation. We integrate modern signal processing, machine learning, and deep learning techniques to develop intelligent systems for rehabilitation engineering, healthcare monitoring, and neurotechnology applications. 

Our work spans the complete pipeline from biosignal acquisition and preprocessing to feature extraction, model development, and real-world deployment. We are particularly interested in research that addresses practical clinical challenges, including noisy physiological data, inter-subject variability, limited annotated datasets, explainability of AI systems. We are looking forward to translate laboratory research into reliable and ethical healthcare solutions.

Vision

To build a research environment where human bio signals, modern signal processing, and artificial intelligence come together to produce rehabilitation technology that is rigorous, reproducible, and clinically meaningful.

Mission

The lab works toward this vision through four commitments: 

  • Conduct rigorous human-subject bio signal research using clinical and research grade instrumentation and well-designed experimental protocols. 
  • Develop signal-processing and AI methods that are physiologically grounded, reproducible, and honest about their limitations. 
  • Translate findings into rehabilitation applications  assistive devices, therapy-monitoring tools, and quantitative clinical assessments. 
  • Train students who are fluent across the full pipeline, from electrode placement and protocol design to model deployment and clinical interpretation. 

Research Areas

The lab works on a range of problems around biosignals, rehabilitation, and human machine interaction. Instead of fixed themes, our work is better described through the following focus areas:

EEG Based Brain Signal Analysis 

Studying brain activity to understand mental state during tasks, including stress, attention, workload, and engagement. This also includes exploring how brain activity relates to physiological responses during rehabilitation and interaction tasks.

Surface EMG for Upper and Lower Limb Applications

Muscle signals are used for gesture recognition, prosthetic/orthotic control, and movement analysis. This includes both hand/wrist tasks and lower-limb activities like gait and sit-to-stand transitions.

EMG Based Human Machine Interaction

Using EMG signals to control assistive or robotic systems in a way that feels natural to the user, with a focus on real-time performance and usability.

Speech and Swallowing Related Signal Analysis 

Work on speech related muscle activity and biosignals, including speech recognition using EMG and monitoring of neck muscle behaviour.

Neck Fatigue and Muscle Activity Monitoring

Studying muscle fatigue in the neck region during prolonged tasks, with applications in ergonomics, rehabilitation, and assistive support. 

Cardiovascular Monitoring (ECG and PPG)

Using ECG and PPG to study heart activity and blood flow, including heart-rate variability, recovery patterns, and wearable monitoring approaches.  

Multimodal Biosignal Integration

Combining EMG, ECG, PPG, EEG, respiration, and other signals to get a more complete understanding of human state during rehabilitation or interaction tasks.  

Stress, Fatigue, and Engagement Assessment 

Using physiological signals to estimate how a person is feeling and performing — including stress levels, mental workload, fatigue, and engagement. 

Machine Learning for Biosignal Analysis 

Applying machine learning and signal-processing techniques to interpret complex biosignals, with a focus on models that generalise well across users. 

Image Processing for Biomedical Applications 

Applying image-processing techniques to analyze visual data in healthcare and rehabilitation, including feature extraction, pattern recognition, and integration with biosignal data for improved assessment and monitoring.
