Why does Nada deserve a spotlight?
As part of Dr. Robert Delatolla’s research group at the University of Ottawa, she leverages the unified wastewater surveillance dataset, a pivotal component of CoVaRR-Net’s WWSRG Major Initiative, to conduct a comprehensive and aggregated examination of wastewater surveillance data quality and its potential in strengthening public health monitoring in smaller communities.
Aliisa Heiskanen
Aliisa Heiskanen, BSc, graduated from the University of Ottawa in 2020 with a bachelor of science for which she majored in biomedical science and minored in psychology. She developed an interest for infectious disease epidemiology during the COVID-19 pandemic and is currently working towards her MSc in Epidemiology at the University of Ottawa. Her research focuses on the seroprevalence of SARS-CoV-2 and seasonal respiratory viruses.
Career Aspiration:
Aliisa hopes to continue working in the field of infectious diseases and assist with pandemic preparedness planning in a research or public health setting.
Why does Aliisa deserve a spotlight?
Since joining the CoVaRR-Net Biobank in September 2022, Aliisa has played critical roles in developing Standard Operating Procedures (SOPs), coordinating the collection of samples and data with study coordinators and partners, and liaising with researchers to arrange shipment of requested samples and data from the Biobank inventory. Her attention to detail has been welcomed in mobilizing the new Biobank Inventory Management System (BIMS). She is also a vital partner within the Data Platform as it heads towards the launch of its dashboard-accessible Metabase platform that will revolutionize sample and data queries, access, and sharing among Canadian researchers. This work is foundational to CoVaRR-Net Biobank operations and its future in pandemic preparedness, particularly as the team continues to build the Canadian Biobank and Data Alliance initiative. Outside of work, Aliisa keeps her mind, body and spirit vitalized through a commitment to athletics: a former varsity basketball player and current triathlete. This fosters an ideal work ethic of perseverance, dependability, commitment and excellent – core elements of our amazing Biobank Team!
