Health Data Science and Big Data Analytics

AI Research Group

A multidisciplinary research and development unit that aims to analyze, interpret, and transform large-volume, diverse, and rapidly flowing data generated in the healthcare field into meaningful artificial intelligence models

About Our Research Group

We adopt a systematic approach to understand the complex structure of health data. We develop clinical and administrative decision support systems by integrating data from electronic health records, population-based health statistics, biobanks, and national health systems.

While ensuring the systematic implementation of data-driven health solutions, we prioritize data security, privacy, and ethical use principles. The application of big data technologies in healthcare requires special approaches, particularly in terms of scalability and performance.

The group is developing algorithms that detect inconsistencies in electronic health records, meaningfully complete missing data, and ensure data integrity. This process also includes standardization and harmonization of data from different healthcare institutions.

Our Data Flow Processes

The methodology we use in the processes from collection to analysis of health data

Data Collection and Integration

Data collection from national systems such as E-Nabız, Medula, and e-Prescription is a sensitive process. We use robust integration algorithms in the face of different formats, coding systems, and data quality issues.

Challenge: Ensuring consistency among millions of records and real-time integration

Data Security and Anonymization

We use differential privacy and homomorphic encryption techniques to protect patient privacy. We focus on conducting scientifically valuable analyses while protecting personal information.

Innovation: Secure data sharing with k-anonymity and l-diversity principles

Data Cleaning and Quality Control

Missing values, outliers, and systematic errors are critical issues in big data analysis. We improve data quality with machine learning-assisted data cleaning algorithms.

Value: Reliable analysis results by achieving 95% data quality

Statistical Analysis and Modeling

We reveal complex relationships in health data through time series analysis, survival analysis, and multivariate statistical methods. Bayesian approaches provide uncertainty quantification.

Criticality: Causal inference in epidemiological analyses

Machine Learning and Prediction

We develop prediction models from health data using deep learning, ensemble methods, and transfer learning. Overfitting and bias problems are addressed with specialized validation strategies.

Future: Inter-hospital collaboration through federated learning

Visualization and Reporting

We transform complex analysis results into comprehensible dashboards and interactive visualizations for decision-makers. We provide continuous monitoring with real-time monitoring systems.

Application: Strategic decision support at the ministerial level

Research and Development Focus Areas

Core research topics we focus on with a comprehensive and systematic approach in health data science

Data Structure and Quality Analysis

Health data has high-dimensional, sparse, heterogeneous, and time-dependent characteristics. We develop algorithms that detect missing values, measurement errors, and systematic biases.

Challenge: Standardization and harmonization of data from different institutions

Time Series and Trend Analysis

Seasonal variations in disease prevalence, epidemic waves, and long-term trends are modeled with temporal analysis techniques. We develop hybrid prediction models.

Innovation: Hybrid models supporting short and long-term projections

Differential Privacy

We research differential privacy, homomorphic encryption, and secure multi-party computation techniques that enable scientific research while protecting patient identities.

Value: Ethical data sharing with k-anonymity and l-diversity

Multi-Modal Data Integration

We provide comprehensive analysis capabilities by combining structured, semi-structured, and unstructured health data. Laboratory, clinical notes, and imaging data are integrated.

Criticality: Establishing meaningful relationships across different data types

Transfer Learning and Adaptation

We provide effective solutions for rare diseases and small patient groups by adapting models trained on large datasets to small and specific datasets.

Future: Inter-hospital model sharing with federated learning

Standardization and Interoperability

We support national and international data sharing by developing data models and transformation algorithms compatible with international standards like FHIR, HL7, and ICD-10.

Application: Interoperability of national health information systems
