Biosketch: 

After working for two years at the CNRS on a Feder project: SextoniAedes, Emmanuelle Clervil obtained a PhD in medical entomology within the medical entomology team at the Institut Pasteur de la Guyane, focusing on Aedes aegypti mosquitoes. This experience offered her the opportunity to refine her skills in medical entomology and virology, while also developing her teaching abilities through interventions in the school environment with high school students. 

Currently, she is preparing to take on a position as a medical entomologist at CESPA, where she will focus on a new research topic with a new study model, ticks. A new adventure that promises to be both varied and enriching. 

Nadia KHERIJI – Institut Pasteur de Tunis 

Thesis: Epidemiological and Biological Study of Monogenic and Multifactorial Forms of Diabetes in Tunisia: Impact of Genetic and Environmental Factors 

Quote: “The road is not always a straight line. It’s a curve, and it’s not finished until you keep going” 

Biosketch: 

Dr. Nadia Kheriji is a researcher in Human Biology with expertise in genomics, bioinformatics, and nutritional sciences. She completed her PhD at the University of Tunis El Manar in collaboration with the Pasteur Institute of Tunis, where she focused on monogenic and multifactorial forms of diabetes in the Tunisian population. Her research integrates next-generation sequencing, whole-genome analysis, and statistical methods to advance personalized medicine.    

She published 9 papers in high-impact journals. Dr. Kheriji has presented her research at esteemed international conferences, including the American Society of Human Genetics (ASHG) and the Francophone Diabetes Society (SFD). She is the recipient of several prestigious awards, including the Best Young Research Presenter Award at the African Society of Human Genetics Conference and multiple travel awards. Her contributions extend to teaching and mentoring graduate students, as well as engaging in multidisciplinary projects focusing on the genomics of metabolic diseases. Her primary goal is to enhance scientific knowledge and contribute to personalized medicine and targeted therapies for diabetic patients. 

Florencia RAMMAURO – Institut Pasteur Montevideo 

Thesis: Systemic Approach to the Antibody-Mediated Immune Response Against SARS-CoV-2 

Quote: “Sometimes it is necessary to do science that changes today” 

Biosketch: 

Throughout her career, she has studied the innate and adaptive immune responses in fields such as allergy, cancer, and infection (Leptospira spp., BLV, SARS-CoV-2). Since joining the Immunovirology Lab in 2018, she has led research on the humoral response to Bovine Leukemia Virus (BLV), supported by an INI-CSIC project, and collaborated on studies of bovine pathogens of economic relevance. 

During the pandemic, she developed and optimized ELISA-based methods to detect IgG antibodies against SARS-CoV-2, resulting in three versions of a national ELISA kit. This allowed the evaluation of the humoral response to COVID-19 vaccination in Uruguay, including transplant and chronic dialysis patients, and informed public health decisions on booster doses. These studies led to five peer-reviewed publications, international presentations, and a funded project to detect neutralizing antibodies against variants. 

Currently, she leads a research line on Human T-lymphotropic Virus (HTLV), focusing on molecular epidemiology and immune responses. As part of an HTLV working group integrated into a regional network, she coordinates a PAHO-funded project to enhance HTLV surveillance in South America. Since 2022, she co-coordinates the Immunovirology Lab at the Institut Pasteur of Montevideo. 

Emiliya STOYANOVA – The Stephan Angeloff Institute of Microbiology 

Thesis: A novel approach for treatment by epitope – specific tumor inhibition of mouse model of melanoma 

Quote: “I’m passionate about oncology and immunology and confident that my expertise in these areas will enable me to make a significant contribution to the field of research.” 

Biosketch: 

As a Ph.D. graduate from the Department of Immunology at the Bulgarian Academy of Sciences in Sofia, she is eager to share my research on tumor immunology. Her commitment to oncology and immunology stems from the recognition that current cancer therapies often lack selectivity, leading to challenges and failures in clinical trials. Therefore, developing new targeted drugs is crucial.  

Her work explores hemocyanins—copper-containing glycoproteins with potential as anti-cancer agents. These unique molecules have been effectively utilized to treat superficial bladder cancer and melanoma. In her study, she aimed to selectively suppress tumor progression in a mouse melanoma model using a chimeric protein vaccine that conjugates a hemocyanin molecule to a mimotope peptide resembling the tumor-associated carbohydrate epitope GD3. They successfully demonstrated that the engineered vaccines RtH-GD3P4 and HaH-GD3P4 elicited strong anti-tumor immune responses in the B16F10 murine melanoma model. Their findings indicate multiple mechanisms for tumor suppression and present a promising approach for cancer therapy and vaccine research. 

Khamsing VONGPHAYLOTH – Institut pasteur du Laos 

Thesis: Inventories of Sandfly and Sandfly-borne Pathogens in Laos 

Quote: “Insects are more than just arthropods; they are vital vectors of human diseases, linking nature and public health in ways that impact millions worldwide.”
