In this week’s episode, Anthony Cruz and Maris Schneider are joined by our newly reappointed international commissioner, Lucas Ferreira Marques dos Santos. Lucas is a PhD candidate in the Department of Chemistry, but today he is telling us all about his experience moving to Canada, conducting research as an international student, and sharing the exciting new opportunities he pours his heart and soul into to help make Western a welcoming community for all. Tune in and get ready to think about how your soul is doing!

In this week's episode, hosts Ryan Baxter and Mark Ambrogio interview GradCast's own Scott Walters, a long-time host and producer. Shortly after his successful PhD defence on June 11, Scott's thesis was​ published on the Western website.

Scott's research explored how the feeding patterns of water-associated birds are reflected in the levels of omega-3 fatty acids in their bodies. Surprised by the results, Scott talks the hosts through some of the prevailing hypotheses that contextualized his research and talks through an explanation for his findings.

In their conversation, Ryan and Mark also listen as Scott recounts his journey from the West Coast to Western. With Scott's time at GradCast winding down, they reminisce about collaboration with Radio Western, playing analogue music (vinyl and CDs) live on air, and the importance of family and friends to a well-rounded graduate experience.

In this week's episode, hosts Ryan Baxter and Mark Ambrogio interview John (Jack) Kausch, who recently completed his PhD in Library and Information Science, formally graduating in June. In his research, Jack looks at past attempts to establish a universal language, as a way of communicating knowledge and ideas across linguistic and cultural divides. Attempts to establish a universal language can be said to go back to ancient Egypt and continued with Francis Bacon and the quest for a "perfect language." Using Real Language Character ontology, Jack built, in his dissertation, a knowledge organization system which is a work of art intended to provoke questions concerning our assumptions about the cross-linguistic universality of knowledge, and also demonstrate expanded potentials for information retrieval in the era of machine learning. You can find the web-art implementation of Jack's work here: https://realcharacterlanguage.world *The episode title is a reference to John Wilkins' famous 1668 essay "An Essay Towards a Real Character and Philosophical Language."

This week, PhD candidate Mila Strelnikova gives a crash course into adapting the scientific spirit, and exploring problems in electrochemistry with a basic science focus (and pioneering steps towards making novel, state-of-the-art microscopy approaches usable across Ontario’s nuclear ecosystem!).

What is pitting corrosion? Why is it something that’s harder to catch when we’re inspecting metal equipment breaking down, and why is this important? How are these problems being tackled and broken down in the lab?

Join Chrishma Perera and Victor Lau as they hear more on Mila’s journey in learning about and building at the edge of this field. Come to hear about the electrochemistry and how she’s been supported by a great group of lab mates, and stay a bit longer to hear about her involvements as a grad student outside her research.

People can reach out to Mila via LinkedIn at https://www.linkedin.com/in/liudmila-strelnikova/ ; And find more about the Gateman lab at https://sites.google.com/view/gatemanresearchgroup/home .

In this week's episode, host Mark Ambrogio interviews GradCast alumna Amalie Hutchinson, a PhD candidate in Biology. Amalie was a GradCast host and producer, ultimately serving two terms as Chair and Managing Editor. She returns to GradCast as she prepares to enter the fourth year of her program (after a maternal leave – congratulations, by the way!). In her research, Amalie studies how hummingbirds use torpor, a state of inactivity characterized by a lowered body temperature and decreased metabolic rate, to preserve energy at night. While this phenomenon is not entirely unique to hummingbirds, the extreme temperature they lower their body to is. Amalie is currently looking at the energy demands of migration, using the wind tunnel at Western's Advanced Facility for Avian Research to study how hummingbirds consume energy over long-distance flights. In their conversation, Amalie and Mark also discuss their shared history with GradCast as well as ways of staying grounded as graduate students. Anyone interested in Amalie's research may contact her at: asaab4@uwo.ca

In this week's episode, hosts Mark Ambrogio and Ryan Baxter interview Kelly Wang, a first-year PhD Student in Education. Kelly is exploring how digital media tools can enhance English language learning to support learners who are older adults and seniors. With her research, Kelly aims to contribute to a field that heavily emphasizes supporting children and youth, and less on older adults and seniors in their English language learning journey. The goal of her research is to support older newcomers in English-speaking regions to learn the language more efficiently and with greater confidence.

Tune in to hear Mark, Ryan, and Kelly’s conversation about her family’s immigration story, how it influenced her research, and how she’s preparing for her upcoming comprehensive exam.

In this week's episode, hosts Chrishma Perera and Mark Ambrogio interview Pilar Rodriguez Mata, a PhD Student in Digital Humanities and Hispanic Studies. Pilar is studying Spanish-language tweets written from 2009 to 2022. Rooted in the humanities, Pilar studies the digital form, utilizing coding – to study the more than 3.5 million tweets she collected, with a focus on learning what enormous amounts of data can tell us about feminism in the Spanish-speaking world. Chrishma and Mark talk with Pilar about what brought her to Western, her journey learning computational tools for her research, and how therapeutic music and reading can be for graduate students.

Doing science is never about a single approach. Join hosts Bruno Mesquita and Rafaela Platkin as they chat with guest Camdyn Holmes, a MSc student in Biochemistry whose research compares two different approaches in examining what makes us human. Most people know that our DNA is an important part of who we are, but not all genes are active everywhere in our body. How do scientists study and measure the different ways our genes express throughout our cells?
