Research Interests

I use microbial parasites as model systems to study eukaryote cell and genome evolution. This work also leads to new insights into the molecular basis of host-parasite and parasite-microbiota interactions. My research focus on the mucosal extracellular parasite Trichomonads and the intracellular parasites Microsporidia infecting human and/or animals. Topics include the role of lateral gene transfer and gene duplications in parasite genome evolution, surface and secreted proteins mediating host-parasite and parasite-bacteria interactions and mucosal microbiology, including the microbiota of the digestive tract (gut and oral cavity), the urogenital tract and the respiratory tract.


• Provide a better understanding of eukaryote origins and diversification through comparative genomics and molecular phylogenetics

• Broaden comparative molecular and cellular studies of eukaryotes to provide a more comprehensive picture of their condition

• Contribute to deciphering the molecular and cellular basis of mucosal microbes interactions with their hosts, integrating both pathogens (microbial parasites) and mutualists (including bacteria)

Current Work

My research has the following research foci:

1) Comparative, Evolutionary and Functional Genomics
We are using comparative genomics and transcriptomics to investigate (i) the contrasting roles of vertical and horizontal inheritance, (ii) the role of gene duplications in shaping eukaryotic genomes and (iii) functional importance of specific genes central to host-parasite and parasite-microbiota interactions. These investigations focuses on gene families acquired through horizontal gene transfer and those encoding proteins orchestrating (a) membrane trafficking and (b) host-parasite and parasite-microbiota interactions. These investigations also lead to new insights into human-microbiota interactions contributing to both health or disease.

2) Comparative Cell Biology
We are investigating the molecular and cellular organization of eukaryote endomembranes of endogenous (the secretory and endocytic pathways) and endosymbiotic origins (the mitochondria and their derived organelles hydrogenosomes and mitosomes).

3) Molecular and cellular basis of Trichomonas species pathobiology and host-microbiota interactions
We are investigating the cellular transformation of Trichomonas into amoeba upon contact to host tissue and the cell surface proteins involved in host tissue binding. We are characterisation of novel family of surface metallopeptidases shared between T. vaginalis and a range of human-associated bacteria including the abundant gut microbiota member Bacteroides thetaiotaomicron and relatives. We are also interested in the mechanisms used by the parasite T. vaginalis to evade patients adaptive immune responses.

My teaching is led by my research on the comparative biology of microbial parasites and members of the mucosal microbiota and it aims at inspiring and stimulating students to participate in the process of fundamental research. It also illustrates how new biomedical knowledge can potentially be applied to reduce the impact of infectious diseases and chronic conditions involving host-microbe interactions. My teaching covers a broad range of topics around the molecular cell biology, genomics and evolution of microbial parasites and their bacteria and viral neighbours at mucosal surfaces.  We also cover fundamentals of the host mucosal immune system required to protect us from pathogens and how members of the microbiota contribute to numerous aspects of mucosal homeostasis.
