Summary
👤
SeniorJonathon Vandezande is Director of Computational Chemistry at Rowan with 12 years of experience building user-friendly quantum chemistry tools that let non-experts leverage DFT, xTB, and neural network potentials. He has led mission-critical QM method development at Schrödinger and delivered accelerated spectroscopy and UV-Vis prediction methods in industry roles, blending deep academic training (PhD in Computational and Quantum Chemistry) with practical product engineering. Jonathon contributes to open-source projects such as cclib, where he improved ORCA parsing and thermochemistry support, reflecting a focus on robust tooling and test-driven development. He has run R&D labs and consulted across materials and medical-device domains, pairing hands-on spectroscopy and analytical skills with software automation. Based in Boston, he’s known for making complex computational workflows accessible to practicing chemists while quietly shipping high-performance methods that scale to industry needs.

Contributions summary:Jonathon primarily contributed to the `cclib/cclib` repository by implementing and refining ORCA parser functionality. Their work involved adding, updating, and testing code related to ORCA thermochemistry output, including temperature, enthalpy, entropy, and free energy calculations. The user also added and improved unit tests for these ORCA features, and expanded the parsing to include more complex spectra like TDDFT, ROCIS and dispersion corrections.
