Welcome to the Nienhaus Lab!
We are a new(ish) lab at FSU interested in the nanoscale optoelectronic properties of semiconductors, photon upconversion, materials development and glowy things. We focus on materials synthesis, optical spectroscopy and scanning probe microscopies.

Lea Nienhaus
Lea obtained her PhD from UIUC in 2015. Following her postdoc at MIT, she transitioned to FSU in 2018. Her interests are geared towards pushing the boundaries of optical spectroscopy. Outside of lab, you can find her playing with her cats, biking, swimming or cooking. Additionaly, she enjoys shining UV lights on household objects.
Alex Bieber
Alex graduated from Western Connecticut State University in 2017. His current interests involve studying solid state semiconductors through scanning probe microscopy, optical spectroscopy, and X-ray based techniques. In his free time, you can find him out on the water fishing or at the beach.
Colette Sullivan
Colette graduated from the University of South Carolina Aiken in 2021. Her research interests include exploring photon up-conversion in perovskites using a variety of optical techniques. Outside of lab, Colette enjoys exploring Tallahassee nurseries for more plants and petting dogs.
Rachel Weiss
Rachel graduated from Jacksonville university in 2021. She is interested in synthesizing semiconductor nanocrystals for photon upconversion. In her free time, she enjoys reading, puzzles, thinking of ideas for lab-related tiktoks, and walking her dog, Frankie.
