When Randall Goldsmith was an undergraduate, he was one of those chemistry majors who couldn’t quite figure out which type of chemistry he liked best.  He later learned that it was ok to be interdisciplinary.  When not doing or teaching chemistry, he can be found chasing frisbees or cooking lentil soup.  His least-favorite part of being a chemistry professor is having to (sometimes) tuck in his shirt.

Mike joined the Goldsmith Group in July 2018 after completing his PhD in chemistry at Northwestern University with Professor Rick Van Duyne. His current research revolves around molecular spectroscopy inside photonic crystals. Outside of the lab, Mike enjoys cooking, hiking, playing the bass guitar, and being kept up all night by half-baked ideas.

Lisa-Maria Needham

needham3@wisc.edu

Lisa-Maria is Marie-Skłodowska Curie Global Fellow in the Goldsmith group and joined in January 2021 after completing her Ph.D. and first postdoc in the Lee Lab at the University of Cambridge. Lisa-Maria loves single-molecules and is really excited about developing new techniques to look at the non-fluorescent ones. Her current research is focused on developing new optical microcavity-enhanced methods for single-molecule light scattering. Outside the lab, Lisa-Maria loves outdoor activities, exploring the wilderness, singing, and playing the guitar.

Tzu-Ling Chen

tchen438@wisc.edu

Tzu-Ling joined the Goldsmith Group in Oct 2021. Tzu-Ling’s research life starts with her passion in parity asymmetry in fundamental physics. That is how she met with optical resonators. She loves AMO (atom, molecule, and optics) physics and found there is another amazing world at the intersection of physics and atmospheric chemistry when she worked as a postdoc in Okumura group at Caltech. With expertise in playing laser systems and macro cavity, now she wants to collect the techniques of micro cavity as well. Outside of lab she loves traveling, outdoor activities, exploring tasty foods, or just enjoys an ordinary day with two little kids.

Levi Hogan

lhogan2@wisc.edu

Levi joined the Goldsmith Group in Fall 2016. He wants to spend his scientific career teaching, learning, and trying to merge as many disciplines of science as possible in the name of discovery. Some of Levi’s favorite hobbies include reading books, running, playing and listening to music, firebreathing, and aspiring for world conquest

chvollbrecht@wisc.edu

Ceci is a physical chemistry student that joined the lab in the fall of 2017. While in lab Ceci enjoys working on anything that might lead to learning or making something new and discussing ideas with her great lab mates. Outside of lab she enjoys exploring the Madison area through both hiking and riding her horse, playing on any sports teams she can and helping with science outreach programs

Veronica joined the group in Fall 2017. She thinks single molecule spectroscopy is ridiculously cool. She loves chemistry and loves having the opportunity to learn, teach, and do research. Outside of lab she loves cooking, watching horror movies, eating sour cream & onion chips, and (occasionally) hiking.

Brendan Cullinane

bcullinane@wisc.edu

Brendan is biophysics student who joined the lab in the fall of 2018. He is thrilled to study the chaotic world of protein dynamics as part of the ABEL trap team. Outside of the lab, he enjoys music, dungeons and dragons, and overly dramatic cooking shows.

Katherine joined the group in the fall of 2018. She likes all kinds of chemistry and is eager to combine them in cool new ways! She loves reading, writing, and teaching science, and is grateful to all the incredible teachers who’ve helped her along the way. When not doing chemistry, Katie enjoys playing cello, walking her dog, and laughing at her own jokes.

Beau SchweitzerPicture of Beau Schweitzer

bschweitzer2@wisc.edu

Beau joined the group in the Fall of 2019. After falling for the UW-Madison chemistry department, he decided to come back for more after graduation. He was inspired to be a spectroscopist by one of his professors. He enjoys working with lasers because they’re cool. Besides chemistry, Beau enjoys running, video and board games, and all other sorts of media.

Brandon Hacha

hacha@wisc.edu

Brandon joined the group in Fall 2019. While he calls himself an analytical chemist, it’s mostly because he hasn’t fully accepted being an experimental physical one. He currently works on the photonic crystal project (one of the few that did not already include a Brandon or Brendan). Outside of lab, Brandon enjoys exploring Madison, trying to bake sourdough bread, and following the most boring parts of local and state politics.

masmith49@wisc.edu

Mackinsey is an inorganic chemistry student who joined the lab in Fall 2019. She has always loved trying to figure out how things work, and she’s excited to shoot lasers at catalysts to figure out how they work. Outside of the lab, she enjoys swing dancing, playing with cats, and baking.

Picture of RayRay Czerwinski

rczerwinski@wisc.edu

Ray joined the Goldsmith group in the fall of 2019. She thinks all chemistry is super cool, especially single-molecule spectroscopy. When she isn’t doing science, Ray likes to make music, play tabletop games, and climb things, generally not all at once. She’s the one on the left in that photo.

Alex Fairhall

fairhall@wisc.edu

Alex joined the Goldsmith Group in the Fall of 2020 as a physical chemistry student after a short break from academia. He’s excited to be getting back into research under such a diverse group and looks forward to exploring single molecule spectroscopy in temperatures even lower than Madison’s cold winters. Outside of the lab, he enjoys reading and writing, playing sports such as ultimate frisbee or volleyball, and practicing his Japanese.

Simi Kaur

skaur24@wisc.edu

Simi is a biophysics student who joined the Goldsmith group in the Fall of 2020. Although her first love is Chemistry, she is fascinated by all walks of science and finds it difficult to just choose one field. She is super excited to combine her broad experimental and computational interests as a part of the ABEL trap team. Outside of lab, Simi loves baking sweet treats, trying new foods, traveling to new places, hiking in scenic locations, and learning how to bike.

Julia Rasch

jrasch2@wisc.edu

Julia is an analytical chemistry student who joined the group in Fall 2020. She is excited to develop new instrumentation to study single molecules. Outside of chemistry, Julia enjoys walking her dog, ogling other peoples’ dogs, avoiding writing bios for the group page for nine months, and cooking.

Daniel Sole-Barber

solebarber@wisc.edu

Daniel Sole-Barber, a member of the physical chemistry path, joined the Goldsmith group in Fall 2021. He enjoys learning new spectroscopic techniques, and was immediately intrigued by the idea of single molecule Raman spectroscopy. He hopes to teach one day, but for now is excited by the prospect of doing more research. Outside of the lab, he likes swimming, reading manga, traveling, and playing video/board games.

Samantha Evans

sjevans3@wisc.edu

Sam moved to Madison and joined the Goldsmith group in Fall 2021. Don’t be fooled by the Golden Gate Bridge – she is from Pennsylvania, not California. When it comes to science, she’s an analytical chemistry student with a desire to make microresonators that can enable single-molecule spectroscopy. Away from science, Sam can be found hiding from the sun, doing nail art, and binge-watching television shows at record-breaking speeds.
