Nicolas Grandjean

Professor Nicolas Grandjean is a faculty member at the Swiss Federal Institute of Technology in Lausanne (EPFL), where he has held a professorship since joining in 2004 after a decade-long research career at France's National Centre for Scientific Research (CNRS). Affiliated with EPFL's Physics section, he maintains a dual focus on cutting-edge semiconductor research and innovative physics pedagogy.

Grandjean's research centers on III-nitride semiconductor physics, with particular emphasis on GaN, AlN, and InGaN materials systems. His work spans optoelectronic device development (including LEDs, laser diodes, and photonic integrated circuits), defect engineering in quantum structures, and advanced characterization techniques like electron holography. Recent publications reveal strong trends toward narrow-linewidth UV laser development, supercontinuum generation in crystalline waveguides, and resolving fundamental limitations in nitride-based optoelectronics through defect physics.

Recognized with EPFL's 2015 Teaching Award in the Physics section, Grandjean employs a distinctive pedagogical approach that prioritizes conceptual understanding over mathematical formalism. His classroom integrates live demonstrations to illustrate physical phenomena, while his 'two-scenario' teaching method accommodates diverse learning levels through parallel conceptual and mathematical pathways. He actively promotes student creativity and independence, viewing these as essential for research innovation.

Grandjean champions student involvement in research through dedicated laboratory access initiatives. His advocacy for maintaining human-centered teaching in the digital age is evident in his refusal to develop MOOCs that might replace direct knowledge transfer, emphasizing that 'the most important thing is sharing' and that teaching 'fills the space' through storytelling and relationship-building.
