Andre Laestadius

Andre Laestadius is a Researcher at the University of Oslo's Department of Chemistry, affiliated with the Hylleraas Centre for Quantum Molecular Sciences. His academic roles include leading the Young Research Talent project CCerror (2019–present) and the ERC-funded REGAL project (2022–). He holds a PhD in applied mathematics from the Royal Institute of Technology (KTH), Sweden, and has held positions at Uppsala University and the University of Oslo. His research focuses on coupled-cluster theory and density-functional theory, with applications to molecular electronic structure and quantum chemistry.

Education:

• PhD in Applied Mathematics, Royal Institute of Technology (KTH), 2014
• Master of Science in Biotechnology, Royal Institute of Technology (KTH), 2008

Research Interests: His work bridges mathematics and theoretical chemistry, emphasizing error analysis in coupled-cluster methods, regularization in density-functional theory, and molecular systems under extreme conditions. Key projects include CCerror (error estimates for excited states) and REGAL (regularized density-functional analysis).

Publications: Recent work explores exchange energies in DFT, coupled-cluster theory reanalysis, and paramagnetic current-density functionals. These contributions advance computational methods and theoretical frameworks in quantum chemistry.

Awards:

• ERC Starting Grant (2022)
• Peder Sather Grant (2021–2023)
• Young Research Talent Grant (2019–present)

Grants & Projects: Leads CCerror (RCN-funded) and REGAL (ERC-funded). Collaborates internationally via grants like the Peder Sather Grant with UC Berkeley.

Labs/Teams: Part of the Hylleraas Centre, a hub for quantum molecular sciences, and collaborates with global researchers in computational chemistry and theoretical physics.
