AI Healthcare Research Laboratory

Research for prospective detection, diagnosis, and intervention

The main goal of this research group is to deploy AI technologies for prospective detection, diagnosis, and to recommend interventions. This group is a hub of interdisciplinary researchers developing healthcare technology solutions, performing user behavior analysis, and creating recommender systems. We are drawn together by our conviction to exchange knowledge between methods developers and application-driven researchers. In our active projects, we handle and analyze large, diverse, and time-sensitive data sets, especially in the biomedical field. We collaborate with biomedical researchers, different types of doctors, and medical specialists to address technical and non-technical research issues. We analyze data from cardiovascular patients, create algorithms for malaria detection, and develop models for patient health states and early warning systems. Our work is a part of the broader field of data-driven medicine, where we utilize machine learning to leverage clinical data, generating new biomedical insights and building precise predictive models for disease outcomes and treatment efficacy.

Primary investigator

Carine Mukamakuza

Instructor

Carine Pierrette Mukamakuza holds a bachelor’s and master’s degree in computer science from Central South University, China. She completed her Ph.D. studies at Vienna Technical University in the Vienna Ph.D. School of Informatics.

Mukamakuza is a lecturer, researcher, and entrepreneur. Her research focuses on digital healthcare solutions, business intelligence, data science (specifically machine learning, where she has centered her attention on recommender systems), online social network behavior, and personalization. Using publicly available datasets, she has investigated the extent to which social connections influence user rating behavior over time. Driven by her interest in digital healthcare solutions, Mukamakuza is creating a digital detection project. She is currently focused on Rwanda as a case study, and her long-term goals for the interface are much broader where she envisions creating a system that could be utilized across countries in Africa, and across diseases. Overall, her goal is to construct an effective data management system that has wide usability and high reliability.

About

"My passion for healthcare research stems from a deep desire to improve lives. Witnessing the impact of limited healthcare resources firsthand has fueled my commitment to this field. This drive, coupled with a fascination for technology, led me to explore how information and communication technology (ICT) can revolutionize healthcare delivery.

For aspiring ICT experts in the field of health, especially women, my advice is to embrace your unique viewpoints and champion them. The ability to see challenges from different angles is a powerful asset in this field. Seek mentorship, build strong networks and leverage your skills to make a significant impact. Remember, you are not just building technology, you are shaping the future of healthcare delivery. By harnessing the power of ICT, we can create a more equitable and and accessible healthcare system for all."

Projects

Digital malaria control for the developing world

This project aims to transform the way healthcare providers can prevent, diagnose, and treat malaria in the hardest-hit regions. Malaria remains a pressing public health concern, especially in resource-constrained settings, so the project holds immense promise as it harnesses digital technologies like artificial intelligence (AI) and machine learning (ML).

At its core, the project seeks to revolutionize the traditional approach to diagnosing malaria by leveraging advanced AI and ML algorithms. By integrating these technologies with microscopy—a widely used method for malaria diagnosis—the project aims to automate and streamline diagnoses. This automation will ensure they are accurate and reliable, which are critical factors in effectively managing disease.

Furthermore, this project represents a significant advancement in diagnosing malaria by incorporating a recommender system.

Powered by AI, this system analyzes diagnostic data and patient information to generate personalized treatment recommendations. It tailors treatment plans to individual patients based on their unique characteristics and the specifics of their malaria infection, which enhances the precision and effectiveness of treatment strategies.

AI systems for cardiovascular disease screening in Africa

This project aims to revolutionize how cardiac health is assessed by simultaneously acquiring and analyzing electrocardiogram (ECG) and phonocardiogram (PCG) signals. It aims to understand in detail how cardiac activity functions, as well as to establish a secure, anonymized database of cardiovascular clinical profiles. The project addresses the challenges faced by individuals with cardiovascular disease in Rwanda, such as limited access to essential services and a lack of cardiologists. The study employs an artificial intelligence (AI) model for analyzing ECG and PCG signals, utilizing advanced algorithms like convolutional neural networks (CNNs) and long short-term memory (LSTM) networks. This approach aims to significantly improve how cardiovascular diseases are diagnosed and treated, particularly in resource-limited settings like Rwanda. The project also formed a team of clinical experts in congenital heart defects (CHD) to provide valuable insights on various aspects related to cardiovascular screening tools.
