- Sciographies – Episode 21 – David Barclay, Oceanographer Thu, Nov 05, 2020
In the last Sciographies episode of the year, Dalhousie University pharmacology student
Gracious Kashéké tackles hosting duties to interview David Barclay for a change. When Dr.
Barclay isn’t moonlighting as the host of Sciographies, he’s an associate professor in Dal’s
Department of Oceanography and a Canada Research Chair in Ocean Technology Systems (Tier
Having grown up in Victoria, B.C., Dr. Barclay spent many childhood vacations sailing along the
West Coast. But it was actually a gig as a student researcher and a lifelong fascination with
sound, music, and recording that led Dr. Barclay down a career path in physical oceanography
and underwater acoustics.
Now Dr. Barclay runs the Dalhousie Noise Lab where his team designs technology that can
withstand harsh conditions to record sound waves from the ocean’s surface all the way down
to its deepest trenches. His technology is an essential tool in the fields of naval defence, naval
communication, and marine biology.
Guest host Kashéké sits down with Dr. Barclay to talk about his upbringing, creative side, and
research (including that popular scientific paper on noise in the ocean at the beginning of the

- Sciographies – Episode 20 – Sophia Stone, Molecular Biologist Thu, Oct 29, 2020
In this episode, we interview Dr. Sophia Stone. She’s a molecular biologist and professor in the
Department of Biology at Dalhousie University.
Thanks to mentorship from strong female influences and unwavering commitment throughout
her life, Dr. Sophia Stone built a career in science that can help society answer critical questions
about the future of food security. Her research explores the fundamental principles that explain
how plants respond to their environments and cope with changes. It’s an area of research
that’s especially important today because producing enough food to feed the growing global
population in the face of climate change is an urgent problem in need of solutions.
Host David Barclay sits down with Dr. Sophia Stone to talk about her experience immigrating
from Jamaica to Canada, her career path and research, and her passion for increasing diversity
in STEM fields.

- Sciographies – Episode 19 – Tess Cyrus, Economist Thu, Oct 22, 2020
In this episode, we interview Dr. Tess Cyrus. She’s an economist and associate professor with
Dalhousie’s Department of Economics.
Dr. Cyrus grew up in sunny California, just a stone’s throw away from Disneyland. As a self-
proclaimed bookworm, she spent hours on end reading anything she could get her hands on.
That natural curiosity sparked her desire to escape the American dream and experience life
outside of the United States. She got her chance in university, when she studied abroad for a
year in Scotland. While there, she had the opportunity to travel throughout Europe to witness
other cultures and ways of life — and that’s when she discovered a passion for international
Today, Dr. Cyrus is an associate professor in the Department of Economics and her research
focuses on understanding the forces that bring people together. She studies international trade
and bilateral trade flows with an emphasis on how culture plays a role in these processes.
As an educator, she’s also interested in designing and improving the economics curriculum. Her
commitment to putting her best foot forward for students has been recognized with
Dalhousie’s Faculty of Science Award for Excellence in Teaching.
In this episode of Sciographies, Dr. Cyrus talks to host David Barclay about what it was like to
grow up in a storied place like Southern California, why economics was the subject that
captured her interest (after a short stint in chemistry), and some of her most recent studies on
international trade and economics education.
- Sciographies – Episode 18 – Mark Stradiotto, Chemist Thu, Oct 15, 2020
In this episode, we interview Dr. Mark Stradiotto. He’s a chemist and professor with Dalhousie’s
Department of Chemistry. He has also won teaching awards and is the most recent recipient of
Dal’s Arthur B. McDonald Chair of research Excellence.
Dr. Stradiotto wasn’t planning on becoming a chemist until his third year of university, when a
course in inorganic chemistry (and its professor) sparked his interest in the field. From that
point on, he pursued chemistry as a career path and has become a leader in his field.
Today the Stradiotto Research Group at Dalhousie specializes in the study and design of ligands
— these are ions or molecules that bind to metals, and through that action allow the metals to
react in ways that otherwise wouldn’t be possible. Ligands are incredibly useful in
pharmaceutical chemistry, so some of Dr. Stradiotto’s innovations have even been patented
and commercialized for industry use.
Dr. Stradiotto tells us about his high-school years as a drummer in southern Ontario, his
participation in commercializing research, and his approach to teaching chemistry to
- Sciographies – Episode 17 – Tim Bardouille, Medical Physicist Thu, Oct 01, 2020
In this episode, we interview Dr. Tim Bardouille. He’s a medical physicist and assistant professor
with Dalhousie’s Department of Physics and Atmospheric Sciences.
An early fascination with technology and philosophy sparked his desire to study physics. When
he learned about medical physics — a field focused on the role physics can play when applied in
health and medicine to diagnose and treat patients — he pursued it as a career path.
After working in industry for a few years, Dr. Bardouille went back to school to get his PhD and
worked towards shifting to a research career.
Today his research in Dal’s Biosignal Lab explores how to capture and analyze imaging data on
the brain signals associated with disorders of the motor system, with a goal of creating
technology that helps improve patient outcomes.
Dr. Bardouille tells us about his career path, his research, and his experience organizing a Black
Lives Matter protest in Halifax that led to forming Dal’s new Anti-Racism Action Team.

- Sciographies – Episode 16 – Hal Whitehead, Marine Biologist Thu, Sep 24, 2020
In this episode we interview Dr. Hal Whitehead in his backyard, which overlooks the ocean in
Herring Cove, Nova Scotia. Dr. Whitehead is a marine biologist, a professor in the Department
of Biology, and author of several books. His interest in animal behaviour led to a scientific
career studying the cultural lives of whales (even though his academic life began with an
undergraduate degree in pure mathematics).
He tells us about travelling between Maine, USA and England, UK while growing up, and how
that experience on the eastern seaboard of the United States nurtured an early love of sailing
that persists today.
Now Dr. Whitehead uses his own sailboat to track sperm whales and northern bottlenose
whales at sea for weeks at a time. A handful of graduate students join him to collect visual,
acoustic, and biological data on how the whales behave and communicate with each other.
- Sciographies – Episode 15 – Natalie Rosen, Psychologist & Sexual Health Researcher Thu, Sep 17, 2020
In this episode we interview Dr. Natalie Rosen, a sex therapist, sexual health researcher, and
associate professor of psychology. She tells us about growing up in Ottawa, being inspired by
Dr. Sue Johanson’s sex education broadcast programs, her path through university and grad
school, and insights from her couples-based research on sexual relationships. Dr. Rosen also
tells us about her knowledge mobilization initiative PostBabyHankyPanky.com, which boils
down her research findings into short, informative videos that aim to help new parents talk
about the very common sexual concerns that arise for both partners after having a baby.
- Sciographies – Season Three Trailer Thu, Sep 10, 2020

- Sciographies – Episode 14 – Christine Chambers, Clinical Psychologist Thu, Oct 31, 2019
In this episode, Dr. Christine Chambers tells us about her laser-focus career path and different types of pain. She also shares the motivation behind her deep commitment to science communication and knowledge mobilization.
Dr. Chambers grew up in Halifax, Nova Scotia and knew at 12 years old that she wanted to become a child psychologist. That path began at Dalhousie, a few blocks away from her childhood home, when she took the undergraduate psychology program. Then she finished up her PhD in clinical psychology at UBC and started working as a psychologist, scientist, and professor.
Now Dr. Chambers is a Killam Professor in the Department of Psychology & Neuroscience (Faculty of Science) and the Department of Pediatrics (Faculty of Medicine). She’s a leading figure in pediatric pain management and a member of the Royal Society of Canada’s College for New Scholars, Artists and Scientists.
Her lab is based in the IWK Health Centre and that’s where she churns out evidence-based strategies for helping kids manage pain, while also making sure those strategies are reaching parents, family doctors, and other front-line healthcare providers.
…And here are just a few more titles Dr. Chambers is known by:
- Canada Research Chair in Children’s Pain
- Scientific Director of SKIP: Solutions for Kids in Pain
- Incoming Scientific Director of the C I H R Institute of Human Development, Child and Youth Health
