Now heading back to Montreal in a beautiful #ViaRail Budd car consist with a loco each at the front and back. Not sure, if it is push-pull or pull-push. Either way. We have enough power for a 1-min early departure 🤔 #traintoot

Finished my last talk in a Community Science symposium. I had the pleasure to open the session with a 40 min talk. Fantastic session with excellent discussions on how to start and conduct community science. If you do, you are in for the long haul with a lot of relationship building required, especially if you are tackling a long-standing problem. #communityScience #citizenScience #openScience

Lots of good ideas for teaching and research during the last two days at #x2026. #activeLearning, #peerInstruction and use of #ai in #teaching and #research on display with excellent critical, but respectful discussions. A lot of student involvement, too.

And a very interesting talk from members of the #TAME initiative on the calibration of #lowcost/mid-cost #sensor networks through colocation and “transfer calibration” methodology. Also, season-dependent issues with gas sensors. Very interesting #airquality #x2026

Today I have been to a number of talks that focused on helping students to become members of the departmental #commumtiy - how to create a sense of #belonging through support and providing a welcoming environment in #highered. #x2026

Things are off to a good start at #x2026 with interesting talks and conversations. Today, I will be giving my first of three talks (two on #teaching #science and one on #airquality data analysis from a #citizenscience project ) —

First, I will report on a field course on introductory research practices for first-year students that I teach at #Concordia #ScienceCollege.

After a pleasant and productive train ride to #Toronto, #x2026 is about to start - the annual #Chemistry and #ChemicalEngineering conference (held together this year)

Guilty academic #summer pleasures: Occasionally stopping halfway on my 17 km bike ride to work at my favourite café on the #LachineCanal. At 8 am sharp (when they open) I will have an espresso on the « terrasse » and answer student advising emails. Then arriving at work with a feeling of accomplishment. It does not get much better than that #academicchatter #velomtl

@DanMorgan Ironically, the most iconic of the songs in 5/4 (and other seemingly unusual signatures) was written by … Paul Desmond ;)

Undergraduate Research Day, which runs after each term (S/F/W) at #Concordia in the Department of Chemistry and Biochemistry is such an awesome showcase of #undergraduate #research. I am especially happy for those students who saw me as the advisor when they were struggling in their program (and sometimes in their lives) and proudly presented their work on a poster or defended their Honours thesis in front of a committee. Kudos for your perseverance to overcome challenges not always under your control! #academia

@sellathechemist The atmosphere is a resource that keeps on giving, when teaching thermodynamics - from latent heat transfer to crude models of hurricanes as Carnot cycles and phase diagrams of water-salt mixtures…; it is all there and so relevant for the everyday life (of undergraduates). Opening class discussing a weather phenomenon going on outside the classroom window is so much fun! #academia #teaching #academicchatter

#Introduction I am Gregor Kos, a Senior Lecturer at #Concordia University in #Montreal, #Canada.

I teach #Thermodynamics, #AnalyticalChemistry, Introductory Research Methods and #MachineLearning for Chemists and Biochemists. I am working on hyper-local urban air quality using low-cost sensors.

#Présentation Gregor Kos, maître de conférences à l'Université Concordia de Montréal, au Canada.

J'enseigne la #thermodynamique, #chimieAnalytique, les méthodes de recherche et l'apprentissage automatique (machine learning) aux chimistes et aux biochimistes. Je mène des travaux de #recherche sur la #qualité de l'air en environnement urbain à l'échelle hyper-locale à l'aide de capteurs à faible coût.
