Reference excerpt

Thia (Kiruba) Kirubarajan is a Canada-based electrical engineer and academic, currently serving as a Distinguished Engineering Professor and Canada Research Chair in Information Fusion at McMaster University in Hamilton, Ontario. He is also Associate Chair (Graduate) in McMaster’s Department of Electrical and Computer Engineering.

Academic background and position According to McMaster University, Kirubarajan holds degrees from the University of Cambridge (B.A., M.A.) and from a U.S. institution where he completed his M.S. and Ph.D. studies. He serves as a Distinguished Engineering Professor and Canada Research Chair in Information Fusion within McMaster’s Department of Electrical and Computer Engineering. His faculty page lists research interests including multisensor–multitarget tracking, estimation theory, information fusion, sensor resource management, radar/sonar/image/signal processing.

Research and contributions Kirubarajan is internationally recognized for his work in estimation theory, multisensor–multitarget tracking, and information fusion. His research has been cited extensively in the scientific literature, with his publications collectively accruing over 18,000 citations as of 2025. He has co-authored influential works in data fusion and target tracking, including the chapter "Multitarget–Multisensor Tracking", regarded as a foundational reference in the field. His broader publication record—spanning more than 300 articles—covers topics such as estimation theory, sensor fusion, resource allocation, and statistical signal processing.

Roles and honours Holds the Canada Research Chair in Information Fusion. Distinguished Engineering Professor, Department of Electrical and Computer Engineering, McMaster University. Associate Chair (Graduate Studies), McMaster ECE Department.

Research group and mentorship Kirubarajan leads the Information Fusion Research Group at McMaster, supervising graduate students and researchers on topics such as multitarget tracking, estimation, and data fusion. He has supervised numerous graduate theses, including work on multisensor tracking and target association. One example is the thesis "Multitarget Tracking Using Multistatic Sensors" (2015, McMaster University).

Influence and impact Kirubarajan’s research in information fusion has influenced both theoretical development and applied technologies in radar, sonar, and autonomous sensor systems. His extensive citation record and leadership of a federally funded research chair underscore his impact in the fields of estimation theory and target tracking.

Worked examples

Example 1 — a first encounter with Thia Kirubarajan

Start with the simplest possible case. Write down what Thia Kirubarajan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thia Kirubarajan before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thia Kirubarajan ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thia Kirubarajan

In research: Thia Kirubarajan appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Thia Kirubarajan in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Thia Kirubarajan is common in secondary-school and first-year university syllabi. It links to neighbouring topics Canada Research Chairs, Canadian engineers, Electrical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Thia Kirubarajan outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
