New Look!

I’ve refreshed this site and gone for a bit more of a retro look. A bit of nostalgia :)

Research

My research involves using data science to improve the services provided to people experiencing homelessness, mental health disorders and addiction. This ranges from developing algorithms to help spot folks who need help to creating data tools for staff working in agencies and clinics offering help.

We work in cross-disciplinary teams that include researchers and clinicians from psychiatry, medicine and social work. We are also proud to collaborate with some of the amazing community agencies that provide support to this very important group. These agencies include The Calgary Drop-In Centre, the Calgary Homeless Foundation and the Trellis Society.

Data science can be used in a variety of ways and it is important to emphasize that we are not developing algorithms that automate support and/or treatment decisions. Instead, our goal is to develop tools that provide information to support the human staff doing front line work with individuals who need help.

Here are a few presentations that provide an overview of some of my work.

• Can Chat-GPT Style AI Help Us Understand Emergency Shelter Data?
• Spreadsheets vs AI: When Good Enough is Good Enough
• How to Link Housing/Homelessness Agency Client Records and Preserve Privacy
• Visualizing Journeys Through the Homelessness and Housing System of Care

AI Guiding Principles

As a data scientist, I do sometimes apply AI and machine learning to the problems I work on. AI is evolving quickly and I think all researchers who use it should have some guiding principles to anchor their work. Here are mine:

1. I will not work on a project that involves developing an AI interface (chat or otherwise) to interact directly with a person in crisis.
2. I will not work on an AI project meant to replace a human decision maker or care giver.
3. I will use AI to improve the quality, intepretability and availability of the information that human care givers require to make the best possible decisions for the people they help.

A Note about Language

Language matters and it’s important to use terms that do not further disadvantage the people we’re trying to help. In particular, the use of the term “vulnerable people” can suggest that vulnerability is a property of that group rather than a set of external circumstances they are experiencing, many beyond their control. An excellent discussion of this issue that can be found here.

I am committed to not perpetuating harm with the language I choose. However, this has been a journey for me and some of the language I use in older publications and presentations may fall short of current best practices.
