He is the inventor of the first prototype clinical SdOCT device for eye imaging, built at the Massachusetts Institute of Technology and tested at the New England Eye Center in Boston USA, and the second built at the Nicolaus Copernicus University in Toruń and tested at the Jurasz Ophthalmology Clinic in Bydgoszcz.
Wojtkowski's research focuses on understanding the interaction of light with living tissue and the potential for in vivo imaging using optical methods.
With his work he has made significant contributions to development of the Optical Coherence Tomography (OCT) method and understanding of the two-photon vision phenomenon.
[4] With this work, he broke new ground for in vivo 3D imaging and quantitative morphometric analysis of the human eye, which have been implemented in many medical devices available in ophthalmic clinics around the world.
[7] Wojtkowski's scientific activity has been recognized by several distinguished bodies, including the President of the Council of Ministers of the Republic of Poland (First Degree Award for his habilitation thesis in 2010); Authorities of the Faculty of Physics of the University of Warsaw (Professor Stefan Pieńkowski Award in 2004[8][9]), Authorities of the Warsaw University of Technology (Medal of a Young Scientist in 2008); and the Chapter of the Polityka Weekly Scholarships (action "Stay with us" in 2001).
