Group members

Juan Pablo Lopez

Principal investigator
C4 Department of Neuroscience

Serena Gasperoni

PhD Student

About me: My name is Serena, I am currently a PhD student at KI, and hold a Master's degree in Pharmaceutical Biotechnology from the University of Bologna. My PhD project focuses on understanding the behavioural language, molecular mechanisms, and cellular circuits responsible for the fast-acting and sustained antidepressant effects of psychedelic compounds, using mouse models of chronic stress. When I'm not in the lab, I like spending time in nature, playing the guitar and doing yoga.

Josefin Kenrick

Research assistant

About me: My name is Josefin, and I hold a master’s degree in Molecular Techniques in Life Science from KTH, Karolinska Institute, and Stockholm University. I am a research assistant in the Lopez laboratory, and my project focuses on investigating how exposure to early life adversity can affect susceptibility or resilience to stress later in life. I am interested in the intersection of bioinformatics and molecular neurobiology, particularly in the context of healthcare application. Outside of the lab, I enjoy being in nature, reading, and training Brazilian jiu-jitsu.

Dr. Fatemeh Sadat Zolfaghari

Research Assistant

About me: I'm Fatemeh, a hold a PhD in Exercise Physiology. Currently, I am a research assistant in the Lopez Laboratory. I am interested in exploring neurochemical and molecular markers in animal models of stress and anxiety. When I'm not immersed in scientific pursuits, I find joy in photography. Writing literary texts and poetry has been a cherished activity of mine since I was 9 years old. Additionally, I am deeply passionate about engaging in various sports activities.

Lucas Sébastien Dumargne

MSc Student

About me: I am in the first year of my master’s degree at the ENS de Lyon, France. My project in the Lopez Lab is to set up a pipeline for performing analyses of various social complex behaviours in freely moving mice. Whenever I'm not in the lab, I like to spend time in nature and discover new places in Stockholm.

Manar Manla Hasan

Research Intern/Medical Student

About me: I am undertaking an introductory research course here at KI alongside my studies in the medical programme. In the Lopez lab, I assist in optimizing behaviour detection in freely moving groups of mice within an enriched environment by annotating videos containing multiple behaviors of interest. During my free time, I enjoy participating in outdoor activities and further exploring Stockholm.

Otto Boldemann

Research Intern/Medical Student

About me: I'm a second-year medical student at KI with a growing enthusiasm for research. Currently, I am contributing to an engaging project focused on machine learning-assisted behavioural phenotyping in mice. In this capacity I identify behaviours, in hopes of providing insights to the research team's efforts. When I'm not immersed in my academic pursuits, I find joy in the company of friends and my girlfriend. Additionally, I have a passion for sports such as football and table tennis, as well as strategic games like chess and board games.
