I’ve worked on a variety of projects in the past, ranging from silicon detector calibrations and time series monitoring systems to quantum computing and machine learning.

Most recently, I was a High Energy Particle Physics Researcher at the AMS Experiment working on the upgrade of the AMS Monitoring Interface, a system my colleagues at AMS and I built a few years ago.

Just before that, I was a master’s student in the department of Computer Engineering at METU working in the field of astroparticle physics. During my degree, I worked as a research assistant at METU ImageLab for a while, but was primarily a graduate researcher at METU IVMER and an affiliate at CERN working on the AMS Experiment.
