A community
for researchers.
Since 2021.
ScientiFika brings researchers across Stockholm together to share their science and build a community.
We meet for informal talks about research and academic life, with time for questions and fika.

What we aim for
Community
Meet junior researchers from other groups and universities.
Accessibility & fun
Talks that explain the research without assuming a background in the subject.
Across disciplines
Learn about research beyond your own discipline.
Mentorship & collaboration
Get to know people you might work with or ask for advice.
Our organisers
Gui Franzmann
About Gui
Originally from Brazil, he was one of the founders of the ScientiFika. Inspired by lunch talks during his PhD at McGill University which only juniors research could attend while eating pizza, Gui made sure that from the very beginning delicious Fika was served after every talk. Gui mostly worries about foundational questions in physics, and currently does research in quantum gravity by focusing both on the foundations of quantum mechanics and the foundations of gravity. He shares his time between Nordita and the Department of Philosophy, while most of his free time is spent climbing!
Milena Crnogorčević
About Milena
From Montenegro to Hong Kong, Vermont, and Maryland, Milena found her home in Stockholm in 2023. She is a postdoctoral fellow at the Oskar Klein Centre, keeping herself occupied by thinking about the ways she can use gamma rays, gravitational waves, and neutrinos to search for signatures of dark matter and new physics in the Universe. She is deeply invested in addressing the lack of diversity and equity in the pipeline to becoming an astrophysicist. If not in her office in Albanova, she can be found swimming at Eriksdalsbadet, bouldering, hiking, or getting lost around Stockholm trying to follow the blue dot on Google Maps.
Katy Proctor
About Katy
Originally from Scotland, Katy moved to Stockholm in 2025 after completing her PhD in Western Australia. Her research uses galaxy formation simulations to understand how dwarf galaxies form and how different dark matter models leave an imprint on the galaxies we observe today. When not analysing simulations, she can be found at the climbing gym, running around the lakes of Stockholm, or listening to music.
Ludwig Neste
About Ludwig
He is a PhD student at Stockholm University, researching the mysterious neutrinos with IceCube, located at the SouthPole. Ludwig joined the team to build this website, so if you find any bugs, he is to blame. He loves trying out new and weird coffees, and is still working on his latte-art.
Roukaya Dekhil
Past organisers
Thank you to our past organisers for their work on ScientiFika.
Nikki Arendse
About Nikki
As a Dutch astronomer living in Stockholm, she finds great joy in biking around and ice skating on frozen lakes during winter. Her research focusses on gravitationally lensed supernovae and how they can be applied to determine the Universe’s expansion rate. In addition to beautiful observations of these phenomena, she also uses watercolour paintings to communicate her research. Her passion for science outreach began as a co-founder of ‘Astronomy on Tap’ in Copenhagen, and continues in Stockholm as ScientiFika team member.
Nadia Flodgren
About Nadia
She is a PhD student at Stockholm University but originally from the north of Sweden. In her research she focuses on applying concepts from mathematics to simplify calculations in perturbative quantum field theory. In her free time she enjoys hiking in nature with her dog.
Judit Prat
About Judit
As a Nordita postdoctoral fellow, she explores cosmic history by studying galaxy clustering and gravitational lensing. Alongside her research, she is interested in art and photography, highlighted by her upcoming book, "Chicago in Color," which captures her experiences in Chicago through minimalist photography. She also enjoys the outdoors and is eager to learn more about Nordic culture, blending her professional interests with a passion for community and the Scandinavian natural beauty.
Pavel Štěch
About Pavel
Born in Czechia, Pavel is pursuing a Master’s degree in Theoretical Physics. He came to Stockholm in 2023 after finishing his undergraduate studies in London. When he is not in a library, you can usually find him with a frisbee in his hand, in a climbing gym or just exploring various hot dog stands in the city.
Participant feedback
“As an audience member, I have found the talks I've seen so far to be much more rewarding than a typical research seminar.”
“I strongly believe the Scientific Fika is one of the best OKC/Nordita events for keeping in touch with OKC/Nordita research outside of one's own field.”
“I've learned about subjects outside of my own in a casual, relaxed format that removes the pressure of asking simple/naive questions to an expert in their field. The post-talk fika discussions are also great, and have allowed me to keep in touch with some people outside of my own department.”
Questions and discussion
Who comes to ScientiFika?
Our usual audience is bachelor’s, master’s and PhD students, and postdocs. Selected events welcome senior researchers, faculty and staff too.
See each event’s page for its intended audience.
Who can join?What to expect
Talks cover research and academic life. They are informal, with questions throughout and fika afterwards.

ScientiFika
in Uppsala.
The first ScientiFika Uppsala event took place on 23 April 2026 with Guilherme Franzmann’s “On the nature of time”.
Our partners at ÅSCO, Ångström SciComm & Outreach, continued the programme in the autumn.
Uppsala autumn announcementOur hosts
ScientiFika is hosted by the Nordic Institute for Theoretical Physics and the Oskar Klein Centre.
