Congratulations Dr. Serkan Sirt

We are delighted to congratulate Serkan Sirt on the successful defense of his PhD thesis, Signatures of Coulomb Screening in the Quantum Hall Effect.

Serkan carried out his doctoral research at PDI under the supervision of senior scientist Stefan Ludwig, working within the Nanoelectronics Core Research Area (CReA). His work provides new insights into how Coulomb screening shapes the behavior of electrons in the quantum Hall regime — a topic at the heart of understanding quantum transport in low-dimensional systems.

Serkan defended his thesis before the following committee:

• Chairperson: Prof. Dr. Wolfgang Kuch (Freie Universität Berlin)
• First reviewer: PD Dr. Stefan Ludwig (PDI)
• Second reviewer: Prof. Dr. Piet Brouwer (Freie Universität Berlin)
• Postdoctoral member: Dr. Huiling Mao (Freie Universität Berlin)
• Student member: Federico Baserga (Freie Universität Berlin)

We warmly congratulate Serkan on this important milestone and wish him every success in his future endeavors.
