Steve Callaghan
Lab Manager

Steve has been with the Faculty of Medicine for 19 years.  During this time he was manager for the Canadian Stroke Networks Adenovirus Core Facility, and Lab Manager for Dr. David Park, former director of the uOttawa Brain and Mind Research Institute. Steve has also been a member of several health and safety committees, a member of the hazmat team and a member the procurement services evaluation project group.

Steve has joined the Rousseaux Lab looking to expand his knowledge in the latest molecular biology techniques including gene editing and flow cytometry.

Outside of the lab, he spends his time with his family camping, hiking and related outdoor pursuits.

Konrad Ricke, Ph.D.
Konrad is from Cologne (Köln), Germany, where he did his PhD on mitochondrial impairment in Parkinson’s disease. He showed that mitochondrial dysfunction together with cell type specific characteristics induce the selective vulnerability of neurons in the substantia nigra. Being born in Montréal, Konrad decided to proceed his scientific career in his country of birth and will now incorporate his expertise in mitochondrial biology into projects of the Rousseaux lab. In his spare time, Konrad enjoys canoeing, hiking, cooking and spending time with his family.

Graduate Students
Zoe Fisk, B.Sc.
MSc Student (Neuroscience)
Zoe is from Windsor, Ontario and is a recent Biology graduate from McMaster University. She has previously worked in an ecological genetics lab, where she discovered her love for the scientific process and research. She is excited to blend her laboratory and undergraduate background with her budding interest in neuroscience for her master’s degree, studying how genetic and molecular dysfunction can lead to neurological diseases. Outside of science, she is passionate about music and traveling, but mostly her yellow lab puppy.  
Haley Geertsma, B.Sc.
PhD Student (Neuroscience)
PRC Poole Family Fellowship; IBRO Travel Award, Ontario Graduate Scholarship
Haley is from Winchester, Ontario but received her B.Sc. in Cell and Molecular Biology from Memorial University of Newfoundland. She is pursuing a higher education in scientific research to feed her curiosity and continue learning. She is a dog person at heart but loves her little calico cat. In her spare time Haley enjoys hiking, reading, and relaxing with family.

Cloe (To) Losier, M.Sc.

PhD Student (Cellular and Molecular Medicine)

Co-Supervised with Dr. Ryan Russell

Vanier Scholarship, Ontario Graduate Scholarship

Cloe has recently graduated from the master’s program at the University of Ottawa. Her previous work focused on the link between stress and nutrient sensitive kinases and the pathogen-induced autophagy pathway. She will join the Rousseaux lab as a PhD student. Here, she is extremely excited to deepen her knowledge of advanced techniques in molecular biology and data analysis. In addition to science, Cloe has a strong love for bubble tea which keeps her calm during late night experiments.

Benjamin Nguyen, M.Sc.
PhD Student (Neuroscience)
Ben is from Atlanta, Georgia and completed his BSc and MSc in biomedical sciences at the University of Georgia in the US. There, he participated in blood-brain barrier research regarding stroke and Alzheimer's, which nurtured his passion for neuroscience and led him to join the Rousseaux Lab. He is eager to further his knowledge in cellular and molecular neuropathology to help push the boundaries of science and further our understanding of neurodegenerative diseases and its causes. Outside of the lab, Ben can be found doing videography, exploring new restaurants, and learning the in's and out's of being a Canadian.
Terry Suk, B.Sc.
PhD Student (Neuroscience)
ALS Canada-Brain Canada Trainee Grant, CNMD STaR Award
Terry has always had an interest in science and learning how things work. During his undergrad at Western, he discovered his love for genetics leading him to join the Rousseaux Lab for graduate studies. Here, he hopes to further pursue his interests in understanding genetic effects on complex diseases and discovering new targets to help prevent and treat such diseases. Outside of the lab, he spends his time playing a variety of instruments, hiking, exploring the outdoors, and playing volleyball.
Undergraduate Students
Hayley Lee
Honours student (BIM)
Hayley is in her fourth year of undergraduate studies in Biomedical Sciences at the University of Ottawa. She is fascinated by the molecular regulation of gene expression and is very excited to expand her knowledge as an honours student. In her free time, Hayley enjoys baking, taking long walks with her poodle, and spending time with her family.
Trina Nguyen
Honours student (TMM)
Trina is currently a fourth year undergraduate student at the University of Ottawa studying Translational and Molecular Medicine. With a strong interest in neuroscience and molecular biology, she decided to join the Rousseaux lab for her Honours Project to uncover how protein dysfunction can contribute to neurodegeneration. In her free time, she enjoys playing volleyball, bingeing the latest Netflix series, and spending time with her friends and family.
Nicholas Valentino
Honours student (BIM)
Nicholas is in his fourth year of Biomedical Science at the University of Ottawa and has joined the Rousseaux lab to complete his honours project. In the lab, he will be working towards understanding the binding patterns between alpha-synuclein and DNA. He intends to gain insight into the neuroscience community and how it desires to improve the quality of life of individuals with neurological diseases. In his leisure time, Nicholas enjoys jazz music, chess, and reading.
