Research Staff

Danielle Cazabon, BASc, MScPH

Danielle Cazabon obtained her B.A.& Sc. at the McGill School of Environment, completing a semester of her studies in East Africa. After several years of working in the environmental health field, she returned to McGill University to complete an MScPH. During her studies, she conducted mixed-methods research internationally and was involved in TB research, which furthered her passion for global health and infectious disease. Danielle interned at Grand Challenges Canada in 2016 and currently works as a Project Manager on the TB Reach initiative at the McGill International TB Centre, leaving her with a keen interest in the successful implementation of global health interventions.

Tripti Pande, MScPH

Tripti Pande, currently a Project Manager for the TB Reach initiative at the McGill International TB Centre, obtained her BSc in Microbiology and Immunology at McGill University and completed her MScPH with a concentration in Global Health at Université Laval. Throughout her studies, she developed an interest in infectious diseases and global health which led her to pursue TB research. Tripti finished an internship at Grand Challenges Canada in the Every Woman Every Child Innovation Marketplace in August 2017. She has conducted many quantitative studies during her studies including helping develop a beta version of a TB application for her masters thesis project.

Postdoctoral Fellows

Doctoral Scholars

Sophie Huddart, BSc, MSc
@skhuddart – sophie.huddart@mail.mcgill.ca

Sophie Huddart received a BSc in Immunology and Infectious Disease from Penn State University and a MSc in Biostatistics from the University of Glasgow as a Fulbright Scholar. She has conducted research in immuno-parisitology and statistical clustering methodology but has always been an epidemiologist at heart. In addition to being the team’s number cruncher, Sophie works on diagnostics and patient mortality in the Indian TB epidemic.

Emily MacLean, BSc, MSc

Emily completed her BSc in Biology at Simon Fraser University, and her Masters in Microbiology & Immunology at McGill, where her research focused on cutaneous leishmaniasis. Expanding upon her interest in infectious disease beyond the molecular level, she joined Dr Pai and his team at the McGill International TB Centre as an RA and is now pursuing her PhD in epidemiology. She’s currently working on a project concerning TB diagnostics and biomarkers.

Giorgia Sulis, MD, DTM&IH, ID specialist

Giorgia completed her medical school in Pavia (Italy) in 2011. After graduation, she worked at the University of Brescia (Italy) as a research fellow on HIV in migrant populations until 2013, when she obtained a TropEd Diploma in Tropical Medicine and International Health and started her fellowship in Infectious Diseases (ID) in Brescia. Besides clinical practice, she developed a strong scientific interest in tuberculosis with a particular focus on latent infection and TB/HIV. As a second-year ID fellow, she did an internship at the Global Tuberculosis Program of the World Health Organization Headquarters in Geneva, working with the TB/HIV team. After becoming an ID specialist in September 2017, she enrolled in the PhD program of Epidemiology at McGill University and started working with Dr. Pai at the McGill International TB Center.

Anita Svadzian, MPH
@svadzianita – anita.svadzian@mail.mcgill.ca

Anita Svadzian was a research assistant at the McGill International TB Centre, and is now pursuing a PhD at McGill University. As an RA, she was working on various projects through McGill’s agreement with UNOPS – Stop TB Partnership – TB REACH. Though Anita holds an honours B.A. in Art History and History, she has always had a strong interest in medical fields having worked in clinical research for the Cedar’s Breast Centre at the MUHC for the majority of her undergraduate studies and thereafter. This formative experience inspired her to seek formal training and consequently, she completed her M.P.H. from Boston University with a focus on Epidemiology. She is extremely interested in the social determinants of health and as such her somewhat unorthodox background has helped her in understanding the interdisciplinary dynamics of health research.

Master’s Students

Vaidehi Nafade

Vaidehi recently completed her BSc. in pharmacology at McGill University, during which she worked in preclinical drug research and studied drug resistance. Raised in India and then Montréal, her coursework and clinical experiences in Canada and abroad led her to develop an interest in infectious disease and global health. She then joined the team as a MSc. student in epidemiology in 2017.

Madlen Nash
@madlennash – madlen.nash@mail.mcgill.ca

Madlen is pursuing an MSc in Epidemiology at McGill University. Stemming from her educational background in microbiology and immunology, her global health interests are infectious disease prevention and diagnosis in high-burden, low-resource settings. She currently works as a junior research assistant at the McGill International TB Centre where her most recent project focused on evaluating a new molecular HIV-1 viral load test in India. As a passionate advocate for health and social justice, she is also involved with Universities Allied for Essential Medicines working to improve the accessibility and affordability of medicines and diagnostics.
