## Why They Matter  
Tkatchenko’s work bridged the gap between theoretical chemistry and practical computational tools, enabling more accurate simulations of complex molecular systems. His dispersion models (e.g., DFT-D3) are standard in quantum chemistry software, influencing drug discovery, materials design, and nanotechnology. By integrating machine learning, he expanded the scope of predictive modeling in chemistry. Without his contributions, modern computational chemistry would lack reliable methods for modeling van der Waals interactions.
