Comprehensive Exam Presentation Slides, at University of Waterloo, Tuesday, April 14, 2020:

Overview:

Ongoing colonialism and lack of self-determination for Indigenous peoples in the land known as Canada pose serious obstacles to confronting ecosystem disruption and extractivism, and to moving towards more sustainable paths for future generations, and improved relationships with all beings. With attention to Indigenist perspectives, and in the context of land use -- timber extraction in particular -- I critically analyze a) the literature at the nexus of Indigenous worldviews and western science-based settler epistemologies; and b) the literature on food...

Do changes in cigarette smokers’ frequency of cannabis use influence their chances of successful smoking cessation? Findings from the 2016 & 2018 ITC Four Country Smoking and Vaping Survey, at Society for Research on Nicotine and Tobacco (New Orleans, LA, USA), Thursday, March 12, 2020:

Significance: Cigarette smokers are more likely to use cannabis than non-smokers. Couse may impede successful smoking cessation. This study examined whether changes in cannabis use frequency influenced tobacco smoking cessation outcomes.

Methods: A prospective cohort of representative samples of adult smokers (n=4,480) from Canada, the United States, England, and Australia were surveyed in 2016 and 2018. In each year, smokers were asked how often they typically used cannabis in the previous 12 months. Self-reported use in each year was...

S(ymplectic) duality: where do we stand?, at Fields Institute, Toronto, Friday, February 7, 2020

video of the talk

Around 2007, Braden, Licata, Proudfoot and I came up with the slightly daft idea that certain singular symplectic varieties come in dual pairs whose definition we could not explain, with relations between them that we struggled to articulate, let alone prove. By 2014, we were able to produce at least a coherent list of properties we expected to match in dual pairs, the most striking being a Koszul duality between associated category O's.

This was...

Abstract:

Work on Bezrukavnikov and Kaledin provides a bridge between representation theory and algebraic geometry, giving an equivalence of derived categories between certain categories of coherent sheaves and non-commutative algebras. Their original construction involved a strange detour into the land of characteristic p, but with some insight from 3-d gauge theory, we can avoid this in the case of BFN Coulomb branches,...

PAPER: Claiming neurodiversity: Autism, expertise, and resistance, at National Women's Studies Association Conference 2019, San Francisco, Saturday, November 16, 2019:

Authors:

Patty Douglas, Brandon University

What are we to make of neurodiversity discourse, both in its activist origins and its more recent expansions into the mainstream? Drawing upon blogs, research articles, and popular media, and engaging with critiques from feminist science and technology/disability studies, this paper considers how neurodiversity arguments for a re-valuation of autism and other forms of human variation...

Machine Learning for Modelling and Decision Making in Complex Physical Domains, at Centre for Artificial Intelligence Decision-making and Action (CAIDA), University of British Columbia, Vancouver, BC, Monday, November 4, 2019

Abstract:

My lab at the University of Waterloo carries out work on a variety of topics within Artificial Intelligence and Machine Learning with a focus on using real world problems to discover computational challenges for modelling of uncertainty, dealing with large or streaming datasets, learning predictive models and enabling decision making. In this talk I will provide a brief overview of a few ongoing projects where these challenges arise from different sources. In combustion modelling for energy production and engine design, standard practices...
