Wisconsin Science Festival!

Our group participated in this years Wisconsin Science Festival! We had a booth at the Discovery Expo and Science on the Square. We had many wonderful demos and a lot of fun sharing our knowledge with our community here in Madison!

Group Hike at Devil’s Lake State Park

With numbered nice days left in the year, our group took a trip out to Devil’s Lake State Park to see the Fall colors! There was lots of hiking, swimming, food, and most importantly laughs. More adventures to come for the Bergmann group!

Welcome, new undergraduate student Muneeza Munawar!

Muneeza joined the group at during the Fall semester of 2022. She is a junior majoring in physics and astronomy.

Welcome, rotation student Sophie Vogelsang!

Sophie Vogelsang is a rotating chemistry student. She recently graduated from Vanderbilt University with a BA in Chemistry and History of Art and completed her undergraduate thesis in Dr. Lauren Buchanan’s research group.

LCLS Summer Interns Poster Session Award

One of our talented undergraduates students, Noah Welke, spent the summer at SLAC National Accelerator Laboratory as an intern. There, he did research with Alex Halavanau developing a solid gain medium for XLO at CXI. At the end of the summer, his hard work was awarded well with first place at the LCLS Summer Internship Poster Session! Congratulations Noah, we are very proud of you!

First XUV Spectrum!

We successfully produced our first high harmonic spectrum! What is pictured is a spectrum of our source, which is an 800nm beam, up-converted, using neon, gas through high harmonic generation (HHG) to create an extreme-ultraviolet beam (XUV)!

Welcome, new undergraduate student, Jake Murawski!

In the Spring of 2022 he graduated from UW Madison, where he studied Physics, Mathematics, and Astrophysics. Jake joined the group at the beginning of the summer of 2022.

Congratulations Nikhilesh!

Nikhilesh graduated on May 14th with bachelor degrees in physics and computer science! He will be continuing his career at Brown University in their PhD program. Nikhilesh did great work while he was here, and we will miss him, but we wish him all the best on his new adventure in Rhode Island!

New Postdoc Coming Soon!

Congratulations to Rafaella Georgiou for winning the HORIZON Marie Skłodowska-Curie Postdoctoral Fellowship. Rafaella will join our group for two years in early 2023. Rafaella will use X-ray spectroscopy to probe the chemical speciation of paint materials that led to a revolution in the 15th century, namely the transition from tempera to oil painting in Italy that marked the beginning of the great period of Renaissance art and the creation of some of the most revered masterpieces of all time.
