Mechanical Engineer

Cognito Therapeutics, Inc. is a venture-backed (Morningside Ventures, FoundersX, IAG, Starbloom) late clinical stage company translating scientific findings from MIT into therapeutic approaches for brain health, including Alzheimer’s disease and other neurodegenerative conditions. We were awarded a Breakthrough designation by the FDA in December 2020 based upon our feasibility data that showed our therapy’s strong safety profile and a notable preservation of cognition and function in patients with mild-to-moderate Alzheimer’s. We completed enrollment in our pivotal study, HOPE, in June 2025 and expect to release topline data from the trial in summer 2026. We are a fast-moving, highly motivated team of innovators with the ambitious goal of helping millions of patients and caregivers around the world who are impacted by neurodegenerative conditions. With our patented brain stimulation technology, we are committed to developing convenient, safe and effective neuroprotective therapies to improve brain health and well-being for all.
