AmanPreet Badhwar, PhD, completed her doctorate at McGill University, where she integrated brain imaging, mass spectrometry-based quantitative proteomics and in vivo measures of neurovascular coupling to study the interaction of neuronal and neurovascular damage in Alzheimer’s disease models, and the impact of therapeutics on these two components. In 2014, she was awarded the Canadian Institutes of Health Research Age+ Prize, which recognizes excellence in research on aging, for her work. Currently, a postdoctoral fellow at the IUGM, University of Montreal, under the supervision of Dr. Pierre Bellec, Dr. Badhwar primarily uses fMRI data to study Alzheimer’s disease and to determine how aspects of brain connectivity could be developed as biomarkers of progression in Alzheimer’s disease. Dr Badhwar was the recipient of a post-doctoral fellowship from the Alzheimer's Society of Canada (2015-2017), and a CIHR post-doctoral fellow since 2017. Dr. Badhwar is also involved in public outreach through her artistic works where the topics of brain organization, plasticity, and memory are recurrent. In 2014, she was a winner in the HBM/Neuro Bureau Brain-Art Competition.

Pierre-Olivier Quirion, PhD, completed his doctoral work in Astrophysics in 2006 under Prof. Gilles Fontaine at Université de Montréal. He then went on a postdoc journey, first with Prof. J-C Dalsgaard at Aarhus Universitet in Danmark and at the Canadian Space Agency’s quiet suburb headquarter on the south shore of Montréal, under Dr. Jean Dupuis. In all, he spent about ten years studying the evolution and seismology of white dwarfs and solar like stars. He followed this period with a two years stint in the film industry, working has a Technical Director in the dynamic CGI production environment in downtown Montréal. It is with this eclectic background, always lined with high performance computing, that Dr Quirion joined the SIMEXP lab for two years (2016-18) as a research professional. There, he developed software for MRI image analysis and distributed computing both on bare metal clusters and with the CBRAIN portal. Since early 2018, he joined Compute Canada and Genome Québec, where he keeps working on scientific workflows for high performance computing.
