Patrick Desrosiers – Complexité et simplicité des réseaux de neurones

Mardi, 23 Août

Patrick Desrosiers est un physicien mathématicien qui s’intéresse aux systèmes complexes et tout particulièrement au cerveau. Il cherche entre autres à élucider le problème de la résilience des réseaux de neurones, c’est-à-dire leur capacité à récupérer leur état normal après une perturbation importante (p. ex. pertes de connexions entre les neurones ou surcharge d’influx électriques). Pour y parvenir, son équipe et lui ont développé des méthodes efficaces de réduction dimensionnelle qui s’inspirent de la théorie des graphes et de plusieurs outils mathématiques couramment utilisés en physique, dont le spectre des matrices.

Depuis 2014, Patrick Desrosiers est chercheur au Centre de recherche CERVO et professeur associé au Département de physique, de génie physique et d’optique de l’Université Laval. Il co-dirige le laboratoire de recherche Dynamica, affilié au Centre interdisciplinaire en modélisation mathématique de l’Université Laval

Pour entendre parler de la recherche du professeur Desrosiers, venez au séminaire le 23 août!

 

Renée Hložek – The Big, Dark and Beautiful Universe

Tuesday, August 30th

We are living in an incredible time in the life of the universe, where we can see stars and galaxies in the night sky, and also measure how the universe is expanding! Dr. Renée Hložek will talk about what the universe is made of including dark energy and dark matter, how they shape how our universe as it evolves with time and how the structures we see around us were seeded from quantum fluctuations billions of years ago. She will discuss how observations of the sky at different wavelengths of light tell us about different properties of the universe – and some of the amazing telescopes we are building to unlock the mysteries of the cosmos.

Renée is an Associate Professor at the Dunlap Institute and the David A Dunlap Department of Astronomy and Astrophysics at University of Toronto. She was born in Pretoria, South Africa where she also did her undergraduate degree. She completed her Masters at the University of Cape Town, South Africa before moving to the UK in 2008 as a South African Rhodes Scholar. After four years as the Lyman Spitzer Postdoctoral Fellow at Princeton University, she moved to Toronto in 2016. Her work uses data from telescopes around the world to test the predictions of novel cosmological theories about our universe, how it started, what it contains and how it will end.

Ben Newling – Magnetic resonance imaging in materials science: tricky techniques for awkward situations

Tuesday, September 6th

Magnetic resonance imaging (MRI) is non-invasive and non-optical, which has cemented its usefulness as a tool in clinical medicine. Careful manipulation of the nuclear spins can make MRI sensitive to a variety of physicochemical parameters such as temperature, chemical potential or displacement. These features make MRI a powerful measurement method in materials science. However, MRI signals in most materials are shorter-lived than in the clinic and more difficult to measure. The UNB MRI Centre develops new MRI methods for use in awkward materials in the lab and in the field, from catalysts to chocolate, from sea ice to maple sap.

[CANCELLED] Cornelia Hoehr – How nuclear physics can treat cancer

Tuesday, September 13th

Physics and especially nuclear physics has always played a direct and indirect role in medicine as very early on scientists realized the potential of radiation in medicine. My research focuses on two main areas where radiation is implemented: Proton Therapy dosimetry and Novel isotopes for nuclear medicine. 

TRIUMF operated Canada’s only Proton Therapy centre from 1995 until 2019 and is actively pursuing Proton Therapy research. Cancer treatment with protons takes full advantage of their superior dose deposition versus the traditional treatment with high energy photons. This allows the healthy tissue around the tumor to be spared from excessive harm while destroying the cancer cells, resulting in a very successful cancer treatment. I am investigating ways to improve Proton Therapy even further by investigating novel detectors for dosimetry, treatment monitoring via novel ways of proton range verification, and the use of proton FLASH.

Nuclear imaging and Targeted Radioisotope Therapy (TRT) uses radioactive isotopes to diagnose and treat diseases like cancer. We are researching and developing methods to produce existing and novel medical radioisotopes. This work concentrates on the targets used at medical cyclotrons and spans the fields of engineering, physics and chemistry.

Valery Milner – Spinning quantum objects in a laser centrifuge

September 27th, 2022

Valery Milner investigates quantum “weirdness”, such as superfluidity in liquid helium, using ultrashort laser pulses. His research group taylors the pulses to a very unique shape, known as an “optical centrifuge”, which enables them to spin molecules inside the quantum system of interest. The reaction of the system to the molecular rotation provides them with new information about the quantum world at the molecular nano-scale.

Valerie Booth – Biophysics – what you do when you can’t decide what kind of scientist you want to be when you grow up.

Tuesday, October 4th

Biophysics involves applying physics ideas and techniques to biological and medical problems.  There is a huge variety in the types of projects that biophysicists take on.   Prof. Valerie Booth’s group uses physics, biochemistry and computational techniques to: 1) develop novel antibiotics to help address the growing problem of microbial resistance to our current drugs; 2) learn how the biomolecular machines inside cells continue to operate even though their environment is jam-packed full of other molecules, i.e. very crowded; 3) figure out how lung surfactant, the mixture that coats the inside of all our lungs, helps reduce the surface tension in alveoli and prevents our lungs from collapsing.
