Photochemistry Undergraduate Research Experience (PURE)

PURE is a research initiative to provide an immersive year long research experience in photochemistry starting each summer and continuing through the following Fall and Spring semesters. In this combined theory-experiment experience, undergraduates learn scientific computing along with the spectroscopic techniques required to fully explore new photochemical materials. This unique opportunity is focused on real-world problems and students will work in cross-disciplinary teams while contributing to basic discoveries in physical chemistry.

Since 2021, 16 Lehigh Undergraduates have participated in the PURE program and 3 have graduated with Research Honors in Chemistry so far!

28% of PURE students have continued to Graduate PhD programs
17% have gone to Medical or Dental School
23% have found a job in Scientific Industry

2025-2026

Applications Due Friday Feb 21st

There are a few different focuses this year! Make sure you make it clear which is an interest for you in your application.

1) Photocatalysis. In particular modeling reactions on nanoparticle surfaces.

2) Photophysics in Solar Cells. With a focus on measuring time-resolved spectroscopy of solar cell materials.

3) Molecular Photochemistry. With a focus on measuring and modeling time-resolved spectroscopy

In order to build a clean energy economy, new photochemically-driven reactions are important for efficient solar energy capture and conversion. For the past 50 years, physical chemists, especially spectroscopists and theorists, have built our so-called “chemical intuition” or understanding of how electron and proton transfer reactions occur primarily in the lowest energy states of molecules. However, when driving reactions with light, molecules necessarily become excited. The complex nature of excited states makes them more difficult to predict and understand, and thus we must develop a new chemical intuition for their reactivity. PURE students study cutting edge molecules and materials that harvest solar energy to solve hard chemical problems.
