MECHANISMS OF MEMORY IN THE BRAIN

THE UNIVERSITY OF BRITISH COLUMBIA

DEPT. OF CELLULAR AND PHYSIOLOGICAL SCIENCES

& DJAVAD MOWAFAGHIAN CENTRE FOR BRAIN HEALTH

WE AIM TO UNDERSTAND HOW THE BRAIN FORMS, STORES, AND RETRIEVES MEMORIES.

To do this, we take a multidisciplinary, multiscale approach. We combine cutting-edge experimental techniques with computation, engineering, and mathematics to study memory across the spatial scales of the nervous system: molecules, cells, circuits, and behaviour. With this combination, we aim to generate a comprehensive understanding of the neurobiological rules of memory in both health and disorder. Some examples of our funded projects include study of fear memory, recognition memory, traumatic brain injury, autism spectrum disorder, epilepsy, and schizophrenia, and we gratefully acknowledge our funders of our research.

About Mark

marku2.jpg

Mark S. Cembrowski received his BSc in Mathematics from the University of British Columbia (2007), where he conducted research examining complex oscillatory behaviour of a sixth-order nonlinear partial differential equation. He later received his MS (2008) and PhD (2011) in Applied Mathematics from Northwestern University, where he combined computational modeling and patch-clamp electrophysiology to study retinal processing as a joint student between William Kath, Hermann Riecke, and Joshua Singer.

As a postdoc, Mark worked in the laboratory of Nelson Spruston at the Janelia Research Campus of the Howard Hughes Medical Institute. His research combined computational modeling, big data analysis, transcriptomics, electrophysiology, viral circuit mapping, and animal behaviour to study the role of cell types in memory.

Currently, Mark is an Assistant Professor in the Department of Cellular and Physiological Sciences at the University of British Columbia, and an Investigator with the Djavad Mowafaghian Centre for Brain Health. He is also a Next Generation Leader with the Allen Institute and a Visiting Scientist with the Janelia Research Campus of the Howard Hughes Medical Institute.

In his spare time, Mark practises and teaches yoga, handstands, and calisthenics.

We do not look for any particular skills for applicants; rather, we seek people that are passionate about science and interested in working in a collaborative and supportive lab environment.

How to apply?

All applicants: Applicants interested in the Cembrowski Lab should contact Mark via email at mark.cembrowski [ at ] ubc.ca with a CV, unofficial academic transcript, and a brief and specific explanation of why they are interested in the lab. Emails that do not meet these criteria, or that do not address following additional points, are not responded to.


Postdoctoral applicants: A brief cover letter (2-3 paragraphs) summarizing past work and future goals should be included in the email.

Graduate students: Graduate students can apply to the lab through programs in Neuroscience, Cell and Developmental Biology*, Biomedical Engineering, Bioinformatics, Experimental Medicine, or Mathematics. In the Canadian system, it is important to note that (1) rotations are typically not present in graduate school, and thus (2) applicants should reach out to Mark before applying to their graduate program of interest to assess fit, Applications for September 2024 start are now closed, and the earliest we are considering additional graduate students is September 2025. Applicants interested in a September 2025 start should contact Mark in fall 2024. *Although the CELL graduate program has a March deadline, CELL applicants are encouraged to submit their applications by January 15th for full consideration.

Technicians: A brief explanation of research experience and previously used techniques should be included in the email.

Undergraduate students: We do not take students for volunteer positions, as this perpetuates existing inequities in science. Undergraduate students typically begin in the lab through credit-based opportunities (e.g., via Directed Studies, Honours Thesis). International students typically join via longer stays through programs that are partnered with UBC (e.g. year-long VIRS program placements). For summer positions, current and prior lab members are given priority, but other UBC and Canadian undergraduate students can inquire about full-time positions. Note: our undergraduate positions are currently full, but students are encouraged to reach out to see if there may be upcoming space. Due to high demand, undergraduate positions are typically booked 8-12 months in advance.
