My current research focus is on developing practical techniques for analyzing machine-generated data. Examples of machine data include software logs and traces, business process logs, mobile logs, sensor data, call detail records, financial instrument trades, etc.

A convergence of trends has led to an increase in attention to machine data and the need for advanced processing techniques. The astronomical increase in the number of connected devices and the need to gain valuable insights from huge volumes of data in real time is a significant factor. The emergence of new regulatory frameworks such as GDPR for data collection and management plays also an important role.

Typical applications of my research include system monitoring and surveillance, software development and evolution, security (intrusion and anomaly detection), process optimization, and operational intelligence.

This research is applicable to most industry sectors. So far, I have worked with companies from the following industries: software, telecom, energy, aerospace, and defence. I am currently building a project with a large Canadian financial institution. So stay tuned for more info.
