Farewell, Wenkel

Today, the Li group says farewell to Dr. Wenkel Liang, who successfully defended his Ph.D. dissertation titled “From Geometry Optimization to Time Dependent Molecular Structure Modeling: Method Developments, ab initio Theory and Applications” last month. Wenkel joined the research group in 2004 and has worked on numerous application and development projects resulting in 18 publications […]
