Natarajaswamy Kalleda, PhD

Natraj Kalledagraduated in Biotechnology from Osmania University, Hyderabad, India. After completing his master’s degree, he worked as a researcher in different institutes in India. During his research at University of Delhi, he developed the interest in studying the fungal infections caused by the invasive mold Aspergillus fumigatus and A. nidulans. He designed and developed a specific gene silencing mechanism induced by diced small interfering RNAs in model filamentous and human pathogenic fungus A. nidulans (Kalleda et al. PLoS One, 2013). Subsequently, he applied this method to study essential gene functions in A. fumigatus. In 2013, Kalleda joined the Beilhack lab to investigate immune defense mechanisms against A. fumigatus lung infections. His main research addresses four different topics i) to investigate the timing and magnitude of host immune cell response following A. fumigatus conidial inhalation, ii) to study continuous host defense responses throughout the different developmental stages of fungi iii) to dissect which immune cells fight against infection under immunosuppression iv) to examine how immunosuppressive treatments affect the anti-A. fumigatus properties of immune cells. To this end he is using an interdisciplinary research approach by applying multicolor flow cytometry, invasive lung infection animal models, adoptive cell transfers, electron microscopy, state-of-the-art light sheet fluorescent microscopy (LSFM) and multi-photon laser scanning microscopy to monitor the dynamic interactions of immune cells with Aspergillus conidia and hyphae. In 2017 Natraj defended his thesis and graduated from the Graduate School of Life Science Würzburg of the German Excellence Initiative with the highest distinction, summa cum laude.
