Rate My Professor Lea Nienhaus

Nienhaus's research investigates the intricate structure-property relationships governing light-matter interactions in photovoltaic materials through integrated scanning probe microscopy and optical spectroscopy techniques. Her group examines solid-state perovskite-sensitized photon upconversion, triplet generation processes at perovskite-organic interfaces, and the effects of nanoscale disorder in perovskites, organic semiconductors, and hydrogen-bonded supramolecular networks. This interdisciplinary work spans chemistry, physics, materials science, and engineering. She has earned numerous accolades, including the 2025 ACS ENFL Outstanding Early-Career Investigator Energy Lectureship Award, the 2024 Alfred P. Sloan Fellowship, the 2024 ACS PHYS Journal of Physical Chemistry C Lectureship Award, the 2023 Camille Dreyfus Teacher-Scholar Award, the 2023 NSF CAREER Award, and the 2023 Grammaticakis-Neumann Award. Key publications encompass "Lead the Way: Halide Perovskites as Next-Generation Triplet Sensitizers for Photon Upconversion" (Chemical Reviews, 2025), "Controlling the Fate of Two Triplet States: Solid-State Annihilator Design for Photon Upconversion" (Chemical Science, 2026), and "Advances in Spectro-Microscopy Methods and their Applications in the Characterization of Perovskite Materials" (Advanced Materials, 2024). Her scholarship has amassed nearly 5,000 citations, underscoring her influence in nanomaterials, photon upconversion, perovskites, excitonics, and energy transfer.
