Join Us

Postdoctoral Researchers

We are looking for highly motivated postdocs to join us. If you are interested in joining us, please email Naoki (naoki.taru@ntu.edu.sg). Preference will be given to scholars with interest/expertise in any of the following areas:

• Material growth (CVD, PVD, MBE, or PLD)

• MEMS

• Nano/microfabrication

• Si photonics (waveguides, modulators, or detectors)

Graduate Students

We welcome graduate students from all subdisciplines to join us. Our lab has two fully funded PhD studentships starting in August 2026. If you are interested, please email Naoki (naoki.taru@ntu.edu.sg). During their PhD, the successful candidate will gain hands-on experience in the following areas: 

• Optical measurements and a deep understanding of photophysics

• Growth and synthesis of quantum dots, 1D/2D materials, and organics

• Nanofabrication and demonstration of optoelectronic devices (e.g., LEDs, infrared cameras, and gas sensors)

• Optical and multiphysics simulations (e.g., Lumerical FDTD, COMSOL)

Visiting Students and Undergraduate Students

We welcome visiting students and undergraduate interns year-round. Open to applicants with or without prior experience. Please email Naoki (naoki.taru@ntu.edu.sg).
