Alexander Spears

Alexander Spears is a PhD student investigating light-driven hydrogen evolution using computational methods, exploring how ultrafast laser pulses can enable superior catalytic performance.

PhD Research

Started: February 2023

Alexander’s research focuses on how ultrafast laser pulses transfer energy to molecular systems more selectively than thermal processes. He investigates non-thermal hydrogen surface chemistry at sub-picosecond timescales, potentially enabling novel catalytic pathways for hydrogen production.

Research Approach

His work employs advanced computational methods including:

• Beyond Born-Oppenheimer Dynamics: Modeling electron-nuclear coupling through electronic friction and surface hopping
• Machine Learning Potentials: Reducing computational demands while maintaining accuracy
• Light-Matter Interactions: Understanding energy transfer mechanisms at ultrafast timescales

Background

Alexander completed both his undergraduate and graduate studies at the Technical University of Munich, specializing in inorganic and computational chemistry. His German education provided strong foundations in both theoretical chemistry and computational methods.

Research Impact

Understanding light-driven hydrogen evolution is crucial for developing sustainable energy technologies. By revealing how laser pulses can selectively activate catalytic processes, Alexander’s work could enable new approaches to green hydrogen production, a key component of the renewable energy transition.
