In this episode, we talk to Dr. Aaron MacNeil (BSc'01), a marine biologist and professor at ��ɫֱ��.�� Dr. MacNeil reflects on his formative experiences growing up in Wolfville, Nova Scotia, where summers spent at Rissers Beach ignited his early fascination with biology. He also shares how the mentorship of an influential high school biology teacher shaped his academic path, leading him to become a researcher in fisheries ecology.

In this episode we talk to Will Burt, a chemical oceanographer and ��ɫֱ�� alum (PhD’15). Dr. Burt is the Chief Ocean Scientist at Planetary Technologies, a carbon dioxide removal company headquartered in Nova Scotia. The company partners with Dal researchers to study the efficacy and safety of ocean alkalinity enhancement (OAE), a mitigation approach that harnesses the ocean’s natural ability to capture and store CO2 from the atmosphere.This special alumni episode, done in partnership with Dal’s Open Dialogue Live series, is the final episode of Sciographies’ fifth season. Host David Barclay interviews Dr. Burt about discovering a passion for oceanography, leaving a tenure-track position in academia to work in industry, and what it’s like to be on the frontlines fighting climate change.

In this episode, we talk to Dr. Kevin Hewitt, a professor and the Associate Dean, Equity and Inclusion in ��ɫֱ��’s Faculty of Science. His research involves designing optical diagnostic tools for disease detection. Outside of his scientific endeavours, he’s passionate about increasing the representation of Black professionals in STEM fields. He was a graduate student when his commitment to this work began with the earliest vision of , which is now a province-wide community partnership that helps to improve student success for youth of African heritage in Nova Scotia. The Natural Sciences and Engineering Research Council of Canada has also named him an inaugural Atlantic-region co-chair for Inclusion in Science & Engineering. Dr. Hewitt talks to us about immigrating to Canada, his mother’s influence on his success, and pursuing research related to health outcomes for African Canadians.

In this episode, we talk to Dr. Michael Freund, a materials scientist, professor and the Harry Shirreff Chair of Chemical Research at ��ɫֱ��. He uses his training in analytical chemistry to do research that informs the design of sensors, electrical devices, and energy storage technologies. He’s also the Director of ��ɫֱ��’s Clean Technologies Research Institute, where he facilitates the resources and funding needed to conduct studies that can help build a more sustainable future. Dr. Freund talks to us about designing sensor arrays that work with machine learning to mimic the brain’s olfactory system, the collaboration between fields to develop new materials, and more.

In this episode, we talk to Dr. Erin Bertrand,�� a marine biogeochemist and associate professor with the Department of Biology. Dr. Bertrand’s research examines the relationship between marine microbes and ocean metabolism. To do this, she travels to challenging environments like the Antarctic to collect samples of ocean water. She’s also a Canadian ambassador for the project. In this episode, she talks to us about pivoting from liberal arts to natural sciences, the challenging fieldwork she conducts in Antarctica, and her commitment to creating an inclusive lab environment for her students.

In this episode, we talk to Dr. Aaron Newman, a cognitive neuroscientist. Dr. Newman developed an early curiosity for computers in the ’80s. While at university, he found a way to combine his interest in technology with his studies in psychology and carved a path for himself in the field of cognitive neuroscience. Today Dr. Newman is a professor and department chair at ��ɫֱ��. He uses technologies like functional magnetic resonance imaging (fMRI) in his research to understand how different language experiences shape the brain. He’s also the director of Nova Scotia’s , a place for STEM students to explore technology, design thinking, collaboration, problem-solving and more.
