I'm Lukas, a passionate theoretical scientist who finds joy in developing theories and algorithms that try to capture the complex physical nature of chemistry.
Curious how quantum chemistry can help predict how current legal and illicit drugs distribute between air, water, and organic matter, and how climate can influence this? 💊🌡️

Quantum chemical calculations for predicting the partitioning of drug molecules in the environment
Regional and temporal trends in legal and illicit drug use can be tracked through monitoring of municipal wastewater, ambient air, indoor air, and house dust. To assess the analytical result for the s...

Computing hydration free energies of small molecules with first principles accuracy
Free energies play a central role in characterising the behaviour of chemical systems and are among the most important quantities that can be calculated by molecular dynamics simulations. The free ene...

We’ve derived and implemented analytical SCF energy gradients for the conductor-like polarizable continuum model with non-static radii.
Another fruitful collaboration with @faccts.de!
