I enjoy exploring the human immune system. In my research, I study human tissue-resident T cells and want to understand how T cells mediate homeostasis in their environment, eliminate threats, improve tolerance, and repair damage.

Currently, I characterize mucosal effector-memory CD4 T cells resident in the human gastrointestinal barrier.

In my PhD at the Center for Infectious Medicine, I uncovered the diversity of mucosal-associated invariant T (MAIT) cells across the human body to understand their role in tissue homeostasis and immune defence. During the COVID-19 pandemic, I joined the Karolinska's efforts to better understand how the human immune system responds to the disease.

Before I joined Karolinska Institutet, I trained as a paramedic, then studied biochemistry at the Friedrich Schiller University in Jena, Germany, with a focus on liver dysfunction and sepsis research.
