Here, we were not only able to see Anna again, but also met many former students and colleagues from other groups. It was a nice occasion to finally  meet and exchange ideas face to face again.

We need help

study-geb400d0c9_1920This semester, our working group is again using an online questionnaire to survey the connection between personality traits and attitudes towards animal experiments. Prerequisites for participation are the age of majority and sufficient knowledge of German to understand the questions. We would be happy about a large participation. Studies

New paper out

Interview with Prof. Dr. Nadja Freund

mic-ga6de09c51_1920Hello Prof. Freund, today I would like to ask you a few questions about you and your laboratory.
Can you briefly tell us about your professional career?



I started my undergraduate studies in Biochemistry with the vision to later work in a pharmaceutical company developing new drugs to treat cancer. However, during my studies I just by chance attended a talk given by Onur Güntürkün and became very fascinated by the brain. That’s why I ended up doing my PhD thesis with him in Biopsychology. Towards the end of my PhD while I still held the fascination of the brain I remembered my early desire to do clinically oriented research. Therefore, pursuing my research career on psychiatric disorder seemed very logical. Fortunately, the fellowship by the Leopoldina allowed me to join the lab of Susan Andersen at McLean Hospital/Harvard medical school where I was able to work with several rat models for psychiatric disorders.


mic-ga6de09c51_1920Which mentor influenced you the most during your professional career?




I am very grateful that I have several mentors who influenced me and who are still available for advice etc. I highly recommend every young scientist to find themselves a mentor (either in a formal setting or someone they informally meet e.g. for coffee). You will learn a lot and even realizing that sometimes your mentor’s way is not your way can be very helpful.


mic-ga6de09c51_1920Why did you choose the branch of research in Psychiatric Disorders?




As mentioned before I was interested in brain research specifically in influences on the developing brain from early on and later wanted a more clinical focus.


mic-ga6de09c51_1920Looking back, was that a good decision?




Yes, it was. I love what I do and think with all the obstacles and rejections for manuscripts and grant applications you get, you need some sort of passion for your work. If I had chosen a topic not based on my interest but on timeliness of on someone else’s advice, I would not have survived in academia.


mic-ga6de09c51_1920What do you enjoy most about your job and what motivates you every day?




Interacting with students and co-workers and discussing research ideas with them. In addition, when I meet with patients I get motivated to advance our knowledge on psychiatric disorders to improve prevention, diagnosis, and treatment options.


mic-ga6de09c51_1920What professional achievements are you particularly proud of?




Two things come to my mind. The first one is the Jule-Angst-Award of the German Bipolar Foundation. I received it for my work to develop an animal model for Bipolar Disorder. As this work was inspirited by a friend of mine who suffers from Bipolar Disorder and is therefore a project quite close to my heard I was extremely proud to receive this prize.
The other one is that I am already ‘mother’ (as in German we call the MD/PhD supervisor Doktormutter) to 3 academic children and supervised several Master students. I am very proud that I could support several young people in starting their academic careers.


mic-ga6de09c51_1920In the last two years we have been accompanied by the Covid-19 pandemic. How has the pandemic affected research and specifically your working group?



Very early at the pandemic we were not even allowed on campus and could only finish very critical experiments. But even later on, working in teams, home office and social distancing made lab life very hard. As mentioned above, I get motivated by interactions with other researchers and think that our work suffered from the loss of informal discussion and crazy research ideas over beer etc.


mic-ga6de09c51_1920What are your goals for 2022?




I really hope that we can go back to more normality in 2022 and have in-person lab meetings and social gatherings. Securing some grant money would be an addition bonus😉 .

Old faces, new projects

WhatsApp Image 2022-04-25 at 14.49.01We are very pleased to welcome Kimberly Bösing and Malin Hedstück back to our laboratory. After completing their bachelor’s degree in our laboratory in 2021, we are pleased to also supervise their master’s theses. Malin and Kimberly are working with the poly I:C schizophrenia mouse model that is already established in our lab. Primarily, they will work with cell cultures. They are looking at the effects of poly I:C activated microglial cells on neural stem cells. Malin focuses on the neurospheres, whereas Kimberly focuses on the neurogenesis of the NSCs. Here’s to another great collaboration.

We have a winner

Our Ph.D. student Patrick Reinhardt won the 3G Grant 2021 at Animal Research Tomorrow. His application has the title: “Improving operant rodent testing in an OpenScience Homecage environment”. The aim of the project is to establish a possibility of operant testing of mice and rats in a system connected to the homecage. We are very proud and congratulate on this success.

From Essen to Bochum

kim 2We are very pleased to welcome Kim Sommer as a new master’s student in our laboratory. Kim completed her bachelor thesis at the University of Duisburg/ Essen in October 2020 and is now working in our laboratory.
Kim will examine rat motivation in a bipolar model in which D1 overexpression can be turned on and off via a viral construct. This overexpression will be examined in the prefrontal cortex, as well as the orbitofrontal cortex, and additionally sex differences will be analyzed. Motivation will be monitored using a progressive ratio task in the mania-like phase and depression-like phase and D1 concentration will be examined by post-mortem tissue analysis. See more
