Marianna is a PhD student in the School of Medicine working on an interdisciplinary project in Optoelectronics with the School of Physics and Astronomy to develop antimicrobial Photodynamic Therapy. PDT is a possible alternative to traditional antimicrobials, considering the continuous growth of resistance to antibiotics by pathogenic microbes and the need for new treatments for these infections. With a Medical background, she has also worked as a General Practitioner directly with patients in situations of vulnerability and lack of resources, including during the COVID-19 pandemic. Her career goal is to pursue new technologies and treatment options for infectious diseases that mainly affect the most vulnerable people in low income countries, particularly in an expected era of antimicrobial resistance.
