Overview

Currently Accepting Graduate Students

Research Interests

My research vision is to develop easy, versatile, and inexpensive methods of exploring and tuning interfaces, particularly in organic, perovskite and nanoparticle solar cells, light emitting diodes and sensors. By making electronic products cheaper, more accessible, and more flexible, our research will have a huge impact on the way people use clean energy, access information and measure the world around them. To achieve this vision, the Turak group uses simple manufacturing approaches(reverse micelle deposition of nanoparticles), allows nature to dictate morphology(entropic self-assembly, beneficial dewetting), and develops widely applicable characterization tools(“MORPHOLOGIES” Monte Carlo simulation code, “dis-Locate” spatial order classification package, 3D printed environmental testing chamber).

Prior to McMaster, I was a Marie Curie Fellow at the Max-Planck-Institute for Metals Research in Stuttgart, Germany (2008-2010), then a visiting professor at Sabanci University in Istanbul, Turkey (2011). I am co-chair for the Society for Information Display (Cnd Chpt), and Editorial Board for the Journal of Materials Science: Materials in Electronics (Springer) and Scientific Reports (Springer-Nature), and Associate editor for Frontiers in Photonics in Photovoltaic Materials and Devices. 

Current research projects include:

  • “Sanitizing plastic": antiviral nanoparticle decorated polymers for antiseptic packaging against COVID-19 (COVID-19 ALLRP 550726-20)
  • Perovskite near and mid-IR nanolasers: Next Generation Sources for Optical Satellite Communications (HTSN-611) (Optical Satellite Consortium Projects, Satellite Canada Innovation Network
  • Nanoparticle Arrays for Novel, Organized Perovskites Assisted by Copolymer assembly Kinetics (NANOPACK): Designer nanomaterials for energy applications (RGPIN-2019-05994)
  • Nanoparticle arrays for light management and degradation control (NanoLight) (Early Researcher Award)
  • High efficiency nanostructured electrodes for organic optoelectronics (NSERC 436100-2013 RGPIN)

As someone expanding from OTFT interfaces to OLED, I just want to thank you for the wonderful review you did back in 2013. I doubt there's been a day this month I haven't consulted it.
