Mona is a postdoctoral fellow specialized in microbial ecology, community ecology, computational biology, and bioinformatics. She holds a Ph.D. in Biology and a DESS (diplôme d'études supérieures spécialisées) in bioinformatics from the Université du Québec à Montréal (UQAM), Canada. Her doctoral research focused on the drivers of plant and soil microbiome diversity and composition in agro-ecosystems and their variation in response to perturbations. This work was funded by Agriculture and Agri-Food Canada. She also has an M.Sc. in Horticulture from the University of Tehran, Iran, where she studied the genetic diversity of Iranian Basil populations. Mona is interested in environmental effects on microbiomes, host-microbe and microbe-microbe interactions, and drivers of microbial community assembly in different environments, including humans, plants and soil. She addresses these objectives by applying ecological theory and using different high-throughput sequencing approaches, including meta-barcoding and meta-omics.
Other than research, Mona enjoys cooking new recipes, traveling and living in different places around the world, learning about different cultures and languages, and exploring science and art integration.

Michelle is a Postdoctoral Associate in the Departments of Physiology & Pharmacology and Pediatrics at the University of Calgary, as part of the Arrieta lab. She holds MSc and PhD degrees in Nutritional Sciences from the University of Toronto (Dr. Deborah O’Connor’s lab) where she studied the role of early-life nutrition for growth and microbiome development of very-low-birth-weight infants. Building upon her prior research, Michelle is now focused on characterizing the complex nutritional and immunological “system” of human milk and its importance for orchestrating microbiome assembly and immune system development in preterm infants as part of the Alberta BLOOM study. Michelle’s research is generously supported by postdoctoral fellowships from the Killam Laureates, Molly Towell Perinatal Research Foundation, and L’Oreal Canada-UNESCO.

BIO:
Emily is a Ph.D. student in the Arrieta lab, holding a Bachelor of Science in Microbiology from the University of Guelph. She completed her undergraduate thesis under the supervision of Dr. Emma Allen-Vercoe, a prominent gut microbiome researcher, which utilized 'Robogut' technology to explore gut microbial community assembly dynamics in naturally depleted ecosystems, such as in inflammatory bowel disease. Emily's interest in the gut microbiome initially stemmed from her passion for travel and experiences abroad, but further evolved as she became curious about the role of early life adversity in our lifelong health trajectories. In her Ph.D. thesis, Emily will explore interkingdom assembly dynamics in the infant gut microbiome and examine the relationship between early life stress and the establishment of the gut microbiome and stress-related brain circuitry in premature infants. Her research interests include microbial ecology, metabolomics, host-microbe interactions, the gut-brain axis, and brain development. Outside of the lab, Emily enjoys hiking, traveling, and the outdoors.
