個人簡介

Dr Carolyn A Cohen joined the HKU-Pasteur Research Pole at the School of Public Health of the University of Hong Kong in 2018 as a Research Assistant, before completing her PhD in 2023. She was supervised by Dr Sophie Valkenburg and supported by the Hong Kong PhD Fellowship Scheme and a Doctoral Entrance Scholarship for Medical Excellence. Her PhD in Immunology was focused on immune response to SARS-CoV-2 infection and vaccination in children and adults.

Her broader research interests are adaptive immunity to viral infection and vaccination with a current focus on SARS-CoV-2 and influenza. She aims to broaden understanding of serological and cellular adaptive immune responses that may contribute to protection against viral infection or severe diseases, particularly in the absence of robust neutralising antibodies. She uses plasma and cells from human clinical samples in classical immune assays to understand specificity, cross reactivity, function and memory of antibodies, B cells and T cells.
