**About Sick

Kids**
Dedicated exclusively to children and their families, The Hospital for Sick Children (Sick

Kids) is one of the largest and most respected paediatric healthcare centres in the world.

As innovators in child health, we lead and partner to improve the health of children through the integration of healthcare, leading-edge research and education.

Our reputation would not have been built - nor could it be maintained - without the skills, knowledge and experience of the extraordinary people who come to work here every day.

Sick

Kids is committed to ongoing learning and development, and features a caring and supportive work environment that combines exceptionally high standards of practice.

When you join Sick

Kids, you become part of our community.

We share a commitment and determination to fulfill our vision of
_Healthier Children. A Better World_
.

Don't miss out on the opportunity to work alongside the world's best in paediatric healthcare.
**Position Description**
We are seeking a postdoctoral fellow to join our research program focused on understanding glial mechanisms of learning and memory.

The Williamson laboratory studies astrocyte biology across cognition, disease, and development.

Our research integrates techniques that span molecular, cellular, circuit, and behavioural neuroscience.

The fellow will help dissect the cellular and molecular mechanisms by which astrocytes control the plasticity and function of memory circuits.

The successful candidate will lead a project focused on: Defining astrocyte responses to neuronal inputs during memory formation
Identifying molecular and cellular mechanisms of astrocyte-neuron interactions underlying learning and memory
Delineating mechanisms of astrocyte allocation to memory-related ensembles
Integrating molecular to behavioural approaches in mouse models for understanding how astrocytes regulate neural circuits and complex behaviours
This position offers a well-defined project with abundant foundational data and cutting-edge theoretical and technical approaches.

The fellow will have opportunities to learn and apply molecular, cellular, circuit, and behavioural neuroscience techniques.

Supportive mentorship, aid with fellowship applications,



and opportunities for publication, presentation, and career development will be provided.
**Here's What You'll Get To Do**
Design, execute, and troubleshoot experiments investigating astrocyte roles in learning and memory using mouse models
Perform stereotaxic surgeries for viral transduction and gene-modification experiments using approaches such as chemogenetic or optogenetic actuators, fluorescent biosensors, cellular ensemble tagging, CRISPR/Cas9-mediated gene editing, and/or overexpression systems
Perform functional assays, including immunostaining, confocal imaging, mouse behavioral assays, chemogenetic manipulations, optogenetic manipulations, circuit mapping, RNA sequencing, and/or fiber photometry
Assist with development, testing, or application of novel molecular genetic constructs
If desired by the fellow, assist with or lead projects related to astrocyte-neuron interactions after stroke and other forms of brain injury.

Analyze and interpret experimental data using standard statistical and analysis software such as Graph

Pad Prism, Imaris, ImageJ, Excel, and R
Contribute to analysis of transcriptomic and/or proteomic datasets, including differential expression, pathway-level analysis, and integration with experimental findings
Stay current with literature on astrocyte biology and learning and memory
Prepare figures, manuscripts, fellowship applications, and presentations
Present findings at lab meetings, seminars, and national or international conferences
Help mentor junior trainees in experimental design, lab techniques, data analysis, and scientific communication
**Here's What You'll Need**
A PhD in neuroscience, physiology, genetics, or a related field, with eligibility for appointment at the postdoctoral fellow level.

Candidates should have no more than four years of cumulative research experience following completion of the PhD.
A conceptual background in astrocyte biology, learning and memory, cognition, molecular biology, neural circuits, or related areas
Experience with _in vivo_ neuroscience, rodent surgery, molecular biology, and/or fluorescence microscopy
Experience with viral transduction, including overexpression, shRNA knockdown, CRISPR/Cas9-based gene modification,



and/or construct design is an asset
Experience with mouse behavioural assays is an asset
Familiarity with basic bioinformatic analysis, including working with transcriptomic datasets and using R for data visualization and analysis is desirable
Strong organizational, analytical, problem-solving, and communication skills
Ability to work independently while contributing to a collaborative team environment
**Employment Type: Full-time temporary 1 year contract, 1.0 FTE**
The principal investigator for this position is Dr.

Michael Williamson, who leads a multi-disciplinary research program focused on astrocyte biology of cognition and disease.

The lab is based in the Neurosciences & Mental Health Program in the Hospital for Sick Children Research Institute.
**Our Commitment to Diversity**
