Meet our team

PD Luise Erpenbeck, MD, lab head

Luise studied medicine in Magdeburg and Göttingen (2003- 2010) and has been interested in neutrophils and tumorimmunology since working on her thesis "Platelet Receptors and Melanoma Metastasis" (defended 2011). She spent 2 years in the lab of Denisa Wagner (Boston Children's Hospital, 2012- 2014) to learn all about NETs, thrombosis and cancer and has been an independent group leader in Göttingen since 2014. When not in the lab she works as a physician in the Department of Dermatology. Hobbies include spending time with her family, reading and singing.

Jason Holsapple, PhD student


Jason joined the lab in August 2021 to study biophysical aspects of the neutrophilic nucleus during NET formation. He previously completed his Master at the University of Aberdeen, Scotland.
Jason enjoys traveling and good food together with his wife and has two lovely if at times capricious cats.  

Anne Schmitz, PhD student


Anne joined the lab in September 2021. She is interested in intercellular communication between neutrophils and uses a wide variety of imaging approaches, including nanomaterial-based novel imaging methods as well as classical biochemical approaches. 
Anne enjoys classical music and plays different types of recorders.

Meike Steinert, technician


Meike is an experienced technician who welcomed us in Münster when we arrived in August 2021and has since then been an amazing help every day. 

Stefanie Deterin, administration

Stefanie helps organise everything in and around the lab with a firm hand. She watches out for all of the lab members and really keeps things running. 

Antonia Luise Gruhn, medical student

Antonia joined the lab in 2018 and has investigated the influence of substrate elasticity in NET formation, a project she competently took over from Gökhan Günay. Her research was recently published in Frontiers of Immunology. She was awarded one of the prestigious research fellowships of DSD (Deutsche Stiftung Dermatologie) for her MD thesis. Antonia is also interested in neurotransmitter singling in the immune system. In her free time, she enjoys Latin American dance and  traveling.  

Thea Mara Husar, medical student

Thea joined us in 2019 to study neurotransmitter signaling in neutrophils. In an impressively short amount of time, she has become our expert at qPCR and her work has led to some unexpected and very exciting data. For her research project, she was awarded the Kurt & Eva Herrmann fellowship of the Alfred Marchionini Foundation. In her free time, Thea bakes the most amazing cakes, enjoys acting and belly-dancing! She is also fluent in Swedish and thinks about moving to Sweden there at some point in her career. 

Former Lab Members

Lukas Mrowietz, medical student

When Lukas joined the lab in 2019, he already had considerable expertise in the field of NET research after working together with  Venizelos Papayannopoulos at the Crick Institute in London. Therefore, he quickly established a new research subject, studying the influence of shear forces on NET formation. 

His preliminary yielded some (pleasant) surprises!
Lukas is also founder of the IT-company WalluM-Systems in Kiel and uses his broad IT-knowledge to develop and adjust algorithms for cell quantifications in the lab (and to maintain our mutual Google calendar - thank you Lukas!). And as if all this were not enough, he is also a talented actor! 



Meike Schaffrinski, technician

Meike joined us in 2019 and very quickly became the heart and soul of the lab. Not only is Meike skilled in (almost) any technique you can think of, she made everyone feel at home in the lab. Her truly good heart also manifests itself by the fact that she takes care of several adopted dogs and cats in her home.


Fahim Rahimi, medical student


Fahim Rahimi joined us in 2019. He is originally from Afghanistan, were he already discovered his love for dermatology and dermatological research. After moving to Germany, he took up his medical studies and his MD project in Göttingen. His main focus is the characterisation of NET and neutrophils in different inflammatory dermatoses. 
His hobbies include Persian calligraphy, hiking and watching medical documentaries.


Tobias Baldeweg, Master student



Tobias joined us to do his lab rotation and then went on to do his Bachelor in our lab. He went on to do his Masters in our group and has developed and established promising new techniques, including expansion microcopy for immune cells. 


Elsa Neubert, postdoc

Elsa studied pharmacology  in Berlin and briefly worked in a pharmacy before hearing the call of Science and joining our team in 2015. She is working on the molecular mechanisms of NETosis (cosupervised by Sebastian Kruss, Physical Chemistry), the influence of light on neutrophils and the importance of experimental conditions for the induction of NETosis. She also supervises medical students and is involved in our psoriasis projects. She defended her PhD thesis (with "summa cum laude!") and has been awarded the Egon Macher Award 2019 at the ADF as well as the prize of the board of trustees of the UMG for an outstanding publication! Apart from that, Elsa is an incredibly talented musician with a specialty in soprano singing. After her time in our lab she moved to Leiden and is now starting the next step in her career as a postdoc. We miss her here every day but sincerely wish her all the best for her future!

Katharina Marie Bach,  medical student


Kathi joined us in 2016 and took on the very challenging project of the influence of light on NETosis. She did not shy away from delving deep into the physics of light and was rewarded with some very interesting insights. She is currently wrapping up her project while continuing her medical studies. She successfully recently presented her work at the ADF Winter School 2019 and published her research in Frontiers of Immunology.  

Julia Grandke, technician


ulia joined our lab at the beginning of 2016, fresh from school. She has since become an expert at imaging and quantification of NETs, all sorts of histological stainings, mouse handling and neutrophil isolation. Her hobbies include taking care of her puppy (who is probably not a puppy any more since we all last saw him) and horseriding, often together with other members of the lab. She left the lab to study business administration.

Sophie Scheidmann, medical student


Sophie is working on the therapeutic effect of NET inhibitors in psoriasis. We hope that her data will provide new therapeutic targets for psoriasis patients. Sophie is a true globetrotter and has been to Nepal and as an Erasmus student in Warsaw!

Anja Kwaczala-Tessmann, physician


Anja joined our lab in 2015 and has mainly focused on the role of the cytoskeleton during NETosis. She was especially interested in the role of tubulins in neutrophil biology. Anja successfully defended her thesis with "Magna cum laude" in November 2021! Congratulations and well done! 

Rebecca Klischka, medical student


Rebecca also joined us in 2019. She was planning to look into the complex interactions between neutrophils, tumor cells and neurotransmitters. She is one of the most creative people I have met, both in the lab and outside of it. Her hobbies include painting, traveling, learning sign-language... Unfortunately, Rebecca had to interrupt her thesis due to personal reasons. 

Susanne Senger-Sander, physician


Susanne joined us in 2016 and studied the influence of the cytoskeleton during NETosis. Her experiments have been very crucial to our understanding of the molecular mechanism of NETosis. Coincidentially, she came across the intriguing finding that certain experimental conditions greatly influence NETosis, which we have just been able to publish at Frontiers of Immunology.

Veit Matzke, physician

Veit was the first MD student brave enough to join our brand new research group in 2015. He worked overtime to establish basically everything in our lab and managed to end up with a very exciting thesis, which is ready to be submitted. After finishing his medical exam, he decided to join orthopaedic surgery in Bremen, where he appears to be very happy (although we all know that in his heart he will always be part of the dermatology here in Göttingen!). Veit successfully defended his thesis with "Magna cum laude" on the 27th of July 2021. Congratulations!!

Gökhan Günay, PhD student

Gökhan joined our lab in December 2017 and rapidly became very involved in some very promising projects, including the influence of substrate elasticity on neutrophil behaviour and neurotransmitters in the immune system. He decided to leave the lab very spontaneously (actually, over night) in December 2018 and go back to Turkey, his home country.
