Monash University Malaysia Intelligent Lighting Laboratory (MMILL)

Intelligent Lighting Laboratory (MMILL)

The Intelligent Lighting Laboratory was approved and established in 2012 as a campus research infrastructure to support multidisciplinary research in the area of Solid-State Lighting and Green Electronics. In 2015, the lab moved to a dedicated 115m² facility at level 8 of building 5A. Since then, year-on-year, we have consistently enhanced the infrastructure capabilities in supporting external research grants, PhD research, undergraduate teaching, industry and multidisciplinary projects.

Vision & Mission

Vision

The Intelligent Lighting Laboratory (MMILL) aims to provide infrastructure necessary to develop lighting and sensor systems with the ability to enhance productivity of humans, plants and a range of engineering systems.

Our mission is to:

Develop context-aware lighting and sensor systems that integrate basic research with applied engineering to create societal impact.

Constantly engage with industries to realize our research into commercializable outcomes.

Create a research culture that promotes innovation and creativity.

Educate industries and communities on lighting technologies.
