He is a professor at EPFL (École Polytechnique Fédérale de Lausanne) and the director of the Laboratory for Molecular Engineering of Functional Materials at School of Basic Sciences.

[12] A further field of their research encompass organic light-emitting diodes (OLEDs) that are used in the fabrication of digital displays.

[14] His laboratory is located at the EPFL-Sion Energy center, focusing on organic, inorganic lead halide perovskite solar cells and Light Emitting Diodes research.

His laboratory has fabricated blue, green, and red PLEDs with unprecedentedly high external quantum efficiency.

His group has investigated solutions (one-step and sequential deposition) and sublimation-deposited perovskite solar cells and obtained a power conversion efficiency of 25%.

The Times Higher Education named him among "the top 10 researchers in the world working on the high impact perovskite materials and devices".

[26] Nazeeruddin was included as one of the Top 2% Most-Cited Scientists in the world on the list published by Stanford University in October 2022.
