The DATA Lab focuses on solving real-world problems by applying techniques from the broad area of data science and data analytics on both structured and unstructured data. The lab also conducts research on applying machine learning techniques to analyze textual and social media data.

In MODLab, we conduct research on algorithms, analysis, and application of machine learning, optimization and statistical signal processing. With a focus on data science, network science, and intelligent systems, current research interests include the following: 

• Online machine learning and time varying optimization for real-time control and decisions 
• Graph signal processing/machine learning and network data analytics 
• Robust machine learning  
• Privacy-aware machine learning 
• Stochastic and chance constrained optimization  
• Federated learning and distributed optimization 

Application domains include smart power and energy systems, wireless communications and sensor networks, social networks, and healthcare.

Our lab focuses on the study of the broad social and ethical dimensions of computing technologies and related implications of our data-driven society. Starting from a sociotechnical stance, we leverage technical, quantitative, and qualitative methods to engage with issues including:

• Human-computer interaction
• Data privacy and surveillance 
• Data and computer ethics
• Algorithimic bias and fairness
• Social computing
• Health informatics

Director – Dennis Brylow

Trustworthy and Intelligent Computing lab focuses on AI and data science applications, security and privacy, and distributed systems. Our research goals include:

• Mining human-generated and human-related data to improve decision making, healthcare, and understanding of social behaviors; 
• Preserving privacy and security for human-centered computing; 
• Efficiently, economically, and securely utilizing distributed and parallel computing resources. 

We have been applying the theories and tools in the topology of multidimensional data, cryptography, differential privacy, parallel processing, knowledge graphs, data management, and machine learning to address the critical research challenges in these areas.
