What I'm looking for

I'm looking to support researchers in structuring, importing, understanding, and using scientific data, drawing on my computational chemistry background, data discipline, troubleshooting, and clear technical communication.

I'm completing doctoral research at Babeș-Bolyai University, where I've organized and quality-checked roughly 3,000 computational chemistry calculations across spectroscopy, photophysics, hypoxia tracers, and ionization-energy studies.

I turn complex Gaussian, ORCA, Excel, OriginPro, and HPC outputs into traceable datasets, clear figures, and practical documentation. I've authored or co-authored four peer-reviewed publications, including three first-author articles, and collaborate closely with experimentalists, theorists, and clinical researchers.
