Physics engineer · Computational materialsI just started an M.Sc. in Physics Engineering at Ankara University. My B.Sc. thesis used machine learning to predict magnetism in 2D materials, and in the research group I run DFT calculations with VASP on Slurm clusters.
Band structures along Γ–M–K–Γ, run with VASP and Quantum ESPRESSO. Adding a halogen to a Janus surface shifts the bands and changes the band gap. That change is what the project studies.
My B.Sc. thesis asked how far composition alone predicts magnetic ordering in 2D materials. I merged the C2DB and V2DB databases into 141,171 unique compositions and trained a gradient boosting classifier on them.
Predicting magnetic ordering in 2D materials from chemical composition. C2DB and V2DB merged into 141,171 compositions, gradient boosting, ROC-AUC 0.986 and 90.6% recall on the magnetic class. Poster award at the department's thesis presentations (January 2026).
Slurm templates, convergence scans and VASP / Quantum ESPRESSO output parsers I use on clusters, plus the AUSURF112 scaling benchmark from my HPC internship. Standard-library Python, so it runs on login nodes.
Solves the 1D Schrödinger equation numerically and plots the energy levels and wavefunctions live. Works for the harmonic oscillator, infinite and finite wells, a double well and any potential you type in. The first five levels match the analytic (n + ½)ħω.
A completed TÜBİTAK 2209-A project on XSSe (X = Sn, Ti): structure models and DFT calculations of the electronic and optical properties. Presented as a poster at the 29th Condensed Matter Physics Ankara Meeting (Hacettepe University, December 2024) and at the Ankara University 80th Anniversary Student Projects Congress (June 2026).
Length and weight of fish from camera images, aimed at trout farms: YOLO detection, length along the mask's principal axis, then W = aL^b. The measurement code is tested; the detector has only seen a public reef-fish dataset so far.
DFT calculations on two-dimensional materials, focused on electronic and magnetic properties and on the data side of materials analysis.
Nuclear-science computing environments; compiling and running Geant4 and ROOT on Linux.
Rocky Linux HPC environments, node and core benchmarking, custom-compiled scientific software stacks.
I live in Ankara. Open to roles in computational science, materials modelling and high performance computing.
In my free time I produce electronic music.
