Ronni received his PhD from University of Nottingham (UK) in 2019. His PhD research elucidated the molecular mechanisms in Neisseria meningitidis for lipoprotein processing and localisation of Factor H binding protein (FHbp), an antigen currently used in two vaccine formulations against the serogroup B of N. meningitidis. Ronni demonstrated that FHbp, thought to be a lipoprotein, can be exported to the outer membrane without processing due to amino acid substitutions on its signal peptide. This could have implications for vaccine formulation and predicted coverage.

Ronni is originally from Brazil, but has spent time in the US, the UK and Germany for his education. In Singapore, Ronni is a post-doc within the Singapore-MIT Alliance for Research and Technology (SMART), working on a joint project with Prof. Jianzhu Chen (MIT) and Kimberly Kline (NTU). Ronni is part of the SMART Antimicrobial Resistance (AMR) integrated research group which is a unique translational research and entrepreneurship program that aims to solve the growing threat of resistance to antimicrobial drugs. Ronni is particularly interested in harnessing the power of the human immune system to tackle AMR. In keeping with Kline lab interests, Ronni will be working with microorganisms of medical relevance including E. faecalis and E. coli.

You can find Ronni with a book and a cup of coffee when he is not reading an article or planning his next experiment. When not reading, Ronni is planning which country to visit next and the new type of food he could try when in there.
