Queen’s University researchers have secured more than $1 million in research infrastructure funding from the Canada Foundation for Innovation (CFI) John R. Evans Leaders Fund.

“Through this support, researchers will be able to build the foundational research infrastructure required to conduct cutting-edge research, and contribute to important new developments in their fields,” says Kimberly Woodhouse, Vice-Principal (Research).

 A total of nine Queen’s researchers will receive the federal funding in a variety of fields, from the ongoing search for dark matter to investigating stem cells, to probing the transition from suicide ideation to attempts to establishing a mobile-inclusive music theatre makerspace.

The following Queen’s researchers have received funding:

Sheela Abraham (Biomedical and Molecular Sciences) has received $162,500 to further the study of cancer stem cells in relation to chronic myeloid leukaemia using systems biology. With the funding, she plans to investigate cell signaling events outside cells controlled by extracellular vesicles and look into if these extracellular vesicles may be key controllers in the aging of stem cells and how this could lead to cancer. Dr. Abraham will also investigate the possibility of using extracellular vesicles as biomarkers for chronic myeloid leukaemia, which would help doctors detect the disease more efficiently, and improve patient treatment and survival.

Joseph Bramante (Physics, Engineering Physics, and Astronomy) has received $49,970 to better determine dark matter’s origin, character, and connection to known physics. Novel new physics search techniques are being developed alongside identified techniques, including using thermal emission of neutron stars as a signature of dark matter, searches for multiply interacting massive particles at underground laboratories, the abundance of elements like gold in dwarf galaxy as a tracer of so-called “asymmetric” dark matter, and charting dark matter’s interaction with neutrinos.

Julia Brook and Colleen Renihan (Dan School of Drama and Music) has received $40,800 to create a music theatre makerspace in order to examine the development and implementation of music theatre activities with underserved populations, such as students in rural and on-reserve communities as well as seniors and adults with cognitive exceptionalities. Participants will work with facilitators to develop music theatre activities using acoustic and digital music tools as well as custom made sets and costumes from the makerspace.

Kenneth Clark (Physics, Engineering Physics, and Astronomy) has received $189,951 to develop a scintillating bubble chamber to support the ongoing search for dark matter. Direct detection involves the interaction of dark matter in a purpose-built detector such as that used by the PICO collaboration. This group has produced world-leading results for a spin-dependent interaction of dark matter with the backgrounds being the largest issue. The scintillating bubble chamber would identify these backgrounds, leveraging the current efforts for a significant improvement in the dark-matter hunt.

Vahid Fallah (Mechanical and Materials Engineering) has received $125,000 to support research into improving the process of selective laser melting, also called metal 3D printing. In this research program, the selective laser melting processing of reactive/sensitive metals will be optimized for more stability and a less reactive build environment. The former will be achieved by optimizing the laser optics assembly, and the latter will be realized by strictly controlling the build atmosphere through an innovative build enclosure design.

Madhuri Koti (Biomedical and Molecular Sciences) has received $150,000 to support her research program’s goals of identify tumour-specific genetic features that specifically associate with the anti-tumour immune responses and whether these could aid in decision making for combination immunodulatory treatment; design optimal combination of chemotherapy and immunotherapy approaches for use with immune stimulating drugs; and  develop markers of chemotherapy-specific host immune alterations for future design of biomarker guided clinical trials to improve patient outcomes.
 
Bhavin Shastri (Physics, Engineering Physics, and Astronomy) has received $132,500 to establish a facility with an experimental test and measurement platform and an optical probe station to demonstrate photonic integrated circuits for neuromorphic computing. Photonic neuromorphic processors have the potential to outperform microelectronics in energy efficiency and computational speeds by seven- and four-orders of magnitude, respectively.

Jeremy Stewart (Psychology) has received $100,000 to support research into identifying factors that predict the transition from suicide ideation to attempts. This transition is a pivotal target for suicide prevention, but little is known about which youth will make this shift and what processes are involved.  The research will employ electrophysiology, laboratory-based behavioural observation, and real-time, daily Smartphone-based assessments to gain novel insights into the processes involved.

Aaron Vincent (Physics, Engineering Physics, and Astronomy) has received $50,000 for his research into developing novel ways to search for and detect dark matter, using its effect on stars such as the sun, and how to use neutrinos as probes of new physics beyond the Standard Model. This research relies on computer simulations of particle physics and astronomical systems such as stars, clusters, and the cosmos, as well as statistical methods aimed at exploring the many possible models of new physics to compare them with data from dozens of different experiments conducted in underground laboratories, ground-based observatories, and in space.
