He has authored and co-authored over 450 articles in refereed journals and conference proceedings, including two books (WILEY), ten invited chapters and numerous invited talks. Prof. Rafailov coordinated the €14.7M FP7 FAST-DOT project development of new ultrafast lasers for Biophotonics applications and the €12.5M NEWLED project which aims to develop a new generation of white LEDs. Currently he coordinate the H2020 FET project Mesa-Brain (€3.3M, aims to develop 3D nano-printing technology for functional three-dimensional human stem cell derived neural networks) and EPSRC proposal (£960k, compact THz based systems for neuroscience applications). He also leads a few others projects funded by EU FP7, H2020 and EPSRC (UK). His current research interests include high-power CW and ultrashort-pulse lasers; generation of UV/visible/IR/MIR and THz radiation, nanostructures; nonlinear and integrated optics; biomedical photonics.
