The Joyner lab studies how genes regulate the cell behaviors (proliferation, differentiation, migration) that underlie organ development, tissue repair and cancer. They focus on the brain where stem cells must produce hundreds of cell types at the right times and in the correct numbers, and the cells then migrate to the correct positions and synapse with partners. The lab uses sophisticated mouse genetics approaches to probe how cell-cell communication and cell intrinsic genetic programs determine the way by which normal cerebellar circuitry is established and regulates behaviors, or are disrupted in diseases including cancer.

Disclosures

Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.

MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.

Alexandra Joyner discloses the following relationships and financial interests:

  • Science Advances
    Provision of Services

The information published here is for a specific annual disclosure period. There may be differences between information on this and other public sites as a result of different reporting periods and/or the various ways relationships and financial interests are categorized by organizations that publish such data.

This page and data include information for a specific MSK annual disclosure period (January 1, 2019 through disclosure submission in spring 2020). This data reflects interests that may or may not still exist. This data is updated annually.
