Data Visualization Incorporating Social Collaboration for Asset Management

Through this research project the intern will investigate the potential of data visualization incorporating a social collaboration element tied to typical data types in asset management. The partner organization Riva Modeling Systems will benefit from the proposed research by providing its clients with an enhanced asset management tool that allows various groups or individuals within the client organization to collaborate in various data views and to see their interaction records on the central dashboard with visualized data. The impact of this enhancement would include that it would set apart the company from its competitors with this novel collaboration functionality and that it would enable client organizations to engage in more effective collaboration and to achieve more optimal results in asset management.

McMaster MPP in Digital Society: Building a Better Picture of Competition in Canada

CAMP is a Canadian think tank focused on understanding and addressing the issues caused by monopoly and a lack of competition in the Canadian economy. As a driver of economic productivity, strong and effective policy to support competition is key to the future success of the Canadian economy. Key to improving competition in the Canadian economy is building and clearly communicating an informed understanding of the current state of competition, how we got there, and what policy makers might do to improve that trajectory.

Development of plaque assays for marine and freshwater algal and cyanobacterial viruses

Cyanobacterial and microalgal host cells produce a range of bioactive compounds that makes them good candidates for drug discovery. At the same time, they themselves get infected by a range of different viruses. This means that understanding the interplay of these hosts with the viruses that infect them is crucial in order to optimize bioactive compound production and harvesting. There is therefore a need to learn more about the viruses that infect these hosts. A major obstacle is the inability for many of these hosts to grow on a solid media, which in turn does not allow to characterize their viruses by a plaque assay; a common microbiological method for assessing the infectivity of viruses and their lifestyle. This project will develop new plaque assay methods for cyanobacterial and algal viruses, and optimize the growth conditions required for the hosts to grow on solid medium.

Path planning algorithm design for autonomous surveillance and coverage task

This project aims to develop a system that improves how robots with restricted operating ranges plan their indoor paths for cleaning or surveying. By dividing indoor spaces into manageable areas, the system will enable robots to complete their jobs more efficiently, optimally covering all necessary ground. This project involves both algorithm development and its implementation in a format that will be convenient to use for other robotics developers.

Developing Data Strategies to Enable Healthcare Machine Learning

The project “Developing Data Strategies to Enable Healthcare Machine Learning” aims to develop effective strategies to collect, curate, and maintain data in healthcare. A data strategy which enables Artificial Intelligence (AI)/Machine Learning (ML) models plays a pivotal role in building response healthcare solutions. The project is focused on understanding the fairness aspects of care quality at Grand River Hospital in the K-W region. To bring the AI revolution to healthcare systems, it is necessary to accomplish the critical task of understanding state of data collection and establish solid data foundations. The primary goal in the project will be to address this foundational need, which can impact the success of efforts beyond this project. The project will develop and build innovative solutions to strategically foster and stimulate the future advances at the hospital and the University of Waterloo to build healthcare systems for the digital age.

Canadian Parks and Wilderness Conservation Education and Outreach

??The Canadian Parks and Wilderness Society – New Brunswick Chapter is a non-profit organization dedicated to the permanent protection of land, rivers, and ocean areas in New Brunswick. We work to ensure that parks are managed to protect the nature within them, and we promote awareness of our connection to nature and the inherent values of wilderness through our education and outreach programs. ?We work collaboratively with community groups, governments, industry, Indigenous Nations, and individuals across the province, to encourage conservation action. ?Through this project, the intern will work on various outreach and education projects, such as facilitating in-parks, nature education events and activities, and drafting communication materials for our terrestrial and marine conservation campaigns. This work is critical in expanding our reach to more communities in New Brunswick, and increasing environmental awareness, nature stewardship, and support for conservation. ?

Targeting bacteriophage delivery of reprogramming transcription factor gene(s) to astrocytes in CNS by Intelligent Phagemid-Assembled Gene Expression (iPhAGE) technology

This project aims to develop a method for delivering reprogramming transcription factor genes to astrocytes in the central nervous system using Intelligent Phagemid-Assembled Gene Expression (iPhAGE) technology. By constructing specific gene blocks and fusion helper plasmids, synthesizing iPhAGE DNA, and purifying iPhAGE preparations, the project seeks to enhance transfection efficiency and assess immune responses and protection. The participating institutions will benefit from the advancement of biotechnological techniques and potential therapeutic applications for neurological disorders.

User Profile generation for Mobile Ad Targeting

Personalized ad targeting is one of the most important features to ensure a successful advertising campaign—e.g., F-150 ford pickup trucks are best shown to construction workers than teenage girls. Another important aspect of ad personalization is frequency capping the ads. For example, showing the same ad 100 times to 1 user will result in not having any budget left over for others, and this can make or break an advertising campaign. To generalize the targeting strategy across users that have not been observed in the past, either due to lack of data or due to new users, we aim to develop clustering methods based on similarity measure that receives user features as input and then assign the new user to a group of users.

Data Analytics for Improving Door-to-Needle Time in Acute Stroke at Grand River Hospital

It is shown that the rapid administration of treatment in acute stroke patients improves clinical outcomes. In particular, the time it takes to administer treatment once the patient has arrived at the Emergency Department with stroke symptoms is called Door to Needle Time (DTN). The median DTN time at the Grand River Hospital (GRH) currently exceeds the 30-minute target median set by the Canadian Stroke Best Practice Guidelines 2022. The goal of this project is to use data analytics tools to analyze past data to reduce DTN time so that most stroke patients presenting at its Emergency Department receive treatment within a median of 30 minutes.

Multimodal RAG Explainability

This project “Multimodal RAG Explainability (MRAGE)” aims to develop an interactive tool for explaining Large Multimodal Models (LMMs) augmented with retrieval capabilities. LMMs represent a significant advancement in AI, capable of understanding and generating content across multiple modalities like text and images. By employing the retrieval-augmented generation (RAG) methodology, this project queries external knowledge sources to empower the retrieval capabilities and reduce the hallucinations of the model. Counterfactual reasoning will be utilized to formulate explanations by extracting the input data that directly impacts the answer it generates. This approach will illuminate the decision-making process of multimodal LLMs, enhancing their transparency and interpretability.

The project holds the potential to significantly impact fields such as healthcare, law, and finance, where understanding the rationale behind AI outputs is crucial for trust and responsible deployment. An interactive tool enables users to understand the reasoning behind the model outputs and identify potential biases or errors.

A programmable microalgae cultivation platform for sustainable food production and waste resource recovery

The manipulation of gene activity in microalgae (cyanobacteria) offers the possibility of producing energy and materials directly from sunlight, water, and carbon dioxide, contributing directly to more holistic modes of food production, innovative bioproducts and reliable bioenergy solutions that reduce human carbon emissions. Despite their recognized potential, it has proven challenging to develop scalable genetic systems for industrial cyanobacterial strains. We are addressing this challenge, in collaboration with Purify, a local biotechnology company, using Arthrospira platensis (Spirulina). We will optimize Spirulina growth under a range of metal concentrations using a recently developed high-throughput lighting system at the University of British Columbia. Use of this lighting system will enable us to build a series of models describing optimal growth under a combination of different metal and media conditions, and isolate specific components that are essential for increased biomass yield or metal tolerance and recovery. We will use this combined platform to increase Spirulina carbon capture associated with nutraceutical or food production including overproduction of phycocyanin and selected cofactors with antioxidant or health promoting properties as well as potential applications in water treatment. Throughout this project we will work closely with Purify providing a path to market for the research while training highly qualified personnel primed for success in the emerging Canadian bioeconomy.
