We are excited to announce the inaugural Mathematical Oncology meeting in Spring 2023 (30th April - 3rd May) in Phoenix. To support the growing momentum in our field of Mathematical Oncology, we feel the time is ripe to establish a new regularly recurring (annual or bi-annual) meeting that will provide an international venue for collaboration, integration, training and synergy for our exciting fusion of disciplines. We look forward to seeing you in Phoenix to launch the next chapter in Mathematical Oncology as we leverage the power of mathematics to drive forward positive change for patients with cancer. Note: Registration for the meeting will open at a later date.
