Research Staff

Tom Landry Demim
Dr. Thomas Landry PhD

Tom has a background in Neuroscience (BSc Neuroscience, Dalhousie) and completed his PhD in 2011 at the University of Melbourne/The Bionics Institute. His PhD research focused on various effects of auditory nerve stimulation by a cochlear implant in combination with a drug therapy delivered directly into the cochlea in a rodent model of profound deafness. This work involved combining a number of research techniques, including surgery, chronic electrical stimulation, histology, optical and electron microscopy, and neural response recording to electrical and acoustic stimulation. Tom joined Dr. Jeremy Brown’s research team in 2011, bringing to the group expertise in these biological research methods.


Deborah Wright Denim no 2

Ms. Deborah Wright, RN

Deborah has over 30 years’ experience in health care.  After many years in Critical Care, Emergency and Flight Nursing, Deborah moved towards management and administration within Nova Scotia Health Authority.  In 2012 as NSHA’s Cardiology Research Manager, she led the development of the research enterprise and in this capacity managed large-scale projects. In October 2017, Deborah joined Dr J. Brown’s research team as Project Manager and as such provides management and administrative support for Dr Brown’s multiple research endeavors with the focus being on the current AIF project.

Rob is interested in the application of light and sound to the diagnosis and treatment of disease.  Upcoming and ongoing projects include, Developing a microscope that can see through the eardrum for diagnosing hearing disorders and planning ear surgeries, Combining ultrasound and optical treatments for skin disease to allow for efficacious treatment with fewer side effects,Intrasurgical tools for photoacoustic imaging of vasculature during brain surgery, Improved electrical circuit designs to achieve fast, short pulses to create ultrasonic cavitation for histotripsy



Dr. Adrienne Weeks. MD, FRCSC, Division of Neurosurgery, NSHAACW Pic_

Adrienne is a Neurosurgeon and Basic Scientist at Dalhousie University. Her clinical interests are in Neurooncology and Neurovascular. She has slowly made her way from coast to coast in Canada. She began her training at University of British Columbia medical school. From there she moved east to Toronto, where she obtained her PhD working under Dr. Jim Rutka, while completing her Neurosurgery Residency. Her laboratory at Dalhousie focuses on discovering novel therapeutic  strategies for malignant brain cancer.


Dr. James P. Fawcett, PhD, Professor of Pharmacology and Surgery at Dalhousie University


Dr Fawcett completed his BSc, MSc, MScT at McMaster University.  He completed his PhD at McGill and PDF at Toronto Universities.  The Fawcett Lab is interested in developmental neurobiology with an emphasis on intracellular signaling complexes underlying neuronal polarity. We utilize molecular and cellular approaches, combined with mass spectrometry based screens to characterize protein complexes involved in establishing neuronal polarity and synapse



Dr. John Frampton. PhD, Assistant Professor , School of Biomedical Engineering, Dalhousie UniversityJohn Frampton- Denim

Dr Frampton’s laboratory develops new technologies and approaches for microscale tissue engineering with an emphasis on neural tissues. The laboratory is also actively involved in the development of microtechnologies for user-friendly, cost-effective in vitro assays and analysis systems for cells and biomolecules.



Dr. Roger J.  Zemp,PhD, Peng, Professor, Department of Electrical & Computer Engineering, Adjunct Professor, Department of Biomedical Engineering, University of AlbertaDenim

Dr. Zemp’s research interest primarily involve novel methods of biomedical imaging, including biomedical optics and biomedical ultrasound. These new technologies aim to provide information to clinicians and biologists that are presently difficult to obtain with other imaging techniques. He is also interested in technologies for improved drug and gene delivery, and disease diagnosis using biomarkers and ultrasound. His research encompasses system design, physical modeling, micro- and nano-fabrication methods, optics and laser systems, ultrasound hardware and software development, image and signal processing and analysis, molecular biology-based methods, and nanotechnology.
