Yusuf Hamied Department of Chemistry


Dr Johannes H. Haataja graduated with a Ph.D. in Physics from Aalto University, Finland in 2018 under the supervision of Dr Nikolay Houbenov and Prof Olli Ikkala. His Ph.D. studies focused on 3D characterization and on advanced data analysis methods of self-assembled nanomaterialsForward and inverse problems in the field of nanoscience. The forward problems are indicated by arrows progressing from left to right and conversely for inverse problems. The primary goal is to formulate theories governing the self-assembly from components C to stable structures X. However most efforts has to be put on solving X from measured data Y. (© 2018, J. Haataja), and why the incorporation of such methods becomes necessary as nanoscience progresses  to ever more complex structures.

His current research is focused on quantitative analysis on how structural properties of disordered materials relate to their optical properties.
