Experience

PhD Candidate, Experimental Physics

Kläui Group, Johannes Gutenberg University Mainz · supervised by Prof. Dr. Mathias Kläui

Thesis on the structural and magnetic nature of single-crystal layered magnetic materials. Built all measurement devices from scratch, from mechanical exfoliation and dry-transfer stacking through to the cryogenic transport, SQUID, and NV-magnetometry measurements themselves, and wrote the Python instrumentation software (CryoSoft) the lab now uses for cryogenic transport measurements. Five peer-reviewed publications over four years (three first/shared-first-author research articles, one lead-author invited perspective, one co-author article). Established the in-house SEM/EDX characterisation workflow used across the group's fabricated devices, and co-supervised three junior researchers (two summer interns, one Master's student awarded top grade) across the PhD.

Elected Supply Chain Manager, Supply Chain 1 (Antiferromagnetic and Altermagnetic Spintronics)

TRR 173 Spin+X · RPTU Kaiserslautern-Landau and JGU Mainz · DFG-funded, EUR 11 million transregional consortium

Peer-elected to coordinate a research "supply chain": the end-to-end pipeline from growing a material, to measuring it, to modelling it theoretically. Chaired monthly cross-group meetings for 20+ PhD researchers and postdocs across two universities, and brokered collaboration across group boundaries. Led two interdisciplinary Seedfund proposals (2024, 2025, both runner-up) and co-led the 2026 cycle, which won the consortium-wide peer vote with 14 of 24 votes and is now funded and in implementation (an NV-centre benchtop antiferromagnet-imaging proposal). Also engaged in TRR 173 consortium-wide governance alongside student representatives and the Young Researcher College manager.

Co-organizer and Mainz contact, Peking-Mainz Exchange Program on 2D heterostructures (MaP-2D)

Sino-German Center for Research Promotion · joint DFG (Germany) / NSFC (China) mobility grant

Co-organized four bilateral meetings between Chinese and German researchers working on 2D materials, including the Third China-Germany Bilateral Meeting (Beijing, October 2024: 41 scientific presentations, over 100 participants). Led the draft of the mobility project's final report, delivered on schedule to the funding agencies.

Visiting Researcher (pre-PhD)

Kläui Group, Johannes Gutenberg University Mainz

Read out the Néel-vector orientation of the semiconducting antiferromagnet CrPS4 via spin Hall magnetoresistance in Pt/CrPS4 heterostructures. Established the full nanofabrication chain for the subgroup (polymer-based exfoliation and vdW stacking of CrPS4 flakes, MBE and sputter deposition of Pt thin films, electron-beam lithography, ion- beam etching, sputter-deposited gold contacts) and built the cryogenic SMR measurement workflow on a 12 T superconducting magnet, presenting the findings at the internal Kläui Group yearly evaluation. Built the foundational experience in cryogenic spin transport and metal-semiconductor interface measurements that fed forward into the PhD magnon spin-valve project.

Summer Research Intern

Computer-Generated Holography and Optical Imaging Laboratory, Prof. B. R. Boruah · IIT Guwahati

Built a 9,000 FPS DMD-based laser wavefront-shaping pipeline driven by computer-generated holograms, with hologram-side aberration correction via Zernike-coefficient tuning; hardware control and data acquisition in MATLAB and LabVIEW.
