Hannah Hamovitz (hhazel@uoregon.edu)

Hannah graduated from Pacific Lutheran University in 2020 with a Bachelor of Science in Chemistry. While at PLU Hannah worked with Dr. Dean Waldow on the design and synthesis of a single-ion conducting solid polymer electrolyte, aiming to create a material that could help to improve the safety and efficiency of lithium-ion batteries. After doing her first rotation with the Johnson lab in the fall of 2020, Hannah officially joined the group in the summer of 2021. She is currently working on studying a charge density wave within asymmetrical PbSe/VSeheterostructures. She also likes plants.

Fischer Harvel (fharvel@uoregon.edu)

Fischer graduated from Fort Lewis College in Durango, Colorado with a Bachelor of Science in Chemistry. In 2018, at Fort Lewis College, he conducted research with Dr. Kenny Miller synthesizing novel diarylmethane compounds. After graduating and working in an analytical water testing laboratory for a year, he decided to pursue a PhD in Chemistry at the University of Oregon, joining the Johnson lab in the summer of 2021. He is currently studying FexSey/PbSe thin-film heterostructures with a possible novel FeSe2 phase.

Sarah Rich (srich3@uoregon.edu)

Bio: Sarah graduated from the University of Wyoming with a Bachelor of Science in Chemistry (ACS Approved) in 2020. While at UW, she worked in the lab of Dr. Brian Leonard working on the synthesis and characterization of rare earth doped quantum dots. Sarah enrolled in the University of Oregon in the Fall of 2020 to pursue a PhD and joined the Johnson lab in the summer of 2021. Sarah’s current research focus is on the synthesis and characterization Mn containing heterostructures and how the introduction of the 2D magnetic Mn layer might affect the parent heterostructure.

Celsey Price (celseyp@uoregon.edu)

Bio: Celsey graduated from The Evergreen State College with a Bachelor of Arts and Science. She enrolled at the University of Oregon in the Fall of 2021 to pursue a PhD in Chemistry. After rotating with the Johnson lab in Spring 2022, she decided to join the group. Celsey’s intrigue in solid state synthesis and electrochemistry led her to study heterostructures with amorphous silicon and TiSe2 layers for the possible application as a higher capacity anode material. She also enjoys teaching chemistry and baking.

Josh Cooper (joshcoop@uoregon.edu)

Bio: Josh graduated from Stanford University with a Bachelor of Science in Chemistry in 2019, where he researched rigid ladder polymers with Dr. Yan Xia. Following his time at Stanford, Josh worked at Savannah River National Laboratory on hydrogen isotope separation projects for four years before enrolling in the University of Oregon’s PhD in Chemistry program in 2023. He joined the Johnson lab in the summer of 2024 and is interested in SnxPb1-xSe alloys and their associated phase transitions.
