Rukan acquired his Bachelor's and Master's degree in Nanoscience at the University of Hamburg, where he focused on the nanofabrication of resonators using gas-phase deposition techniques within micro- and nanofluidic polymer chips.

Within the group, Rukan focuses on nanofabrication. His project establishes fluidic cells with integrated functionalities, such as membranes for the optical integration of ultrashort laser pulses and metal structures for manipulating and measuring molecules through electric fields.
