Work on late-life suicide

Our lab uses behavioral experiments and neuroimaging to understand decision processes leading to suicidal behavior. We work with older adults who have attempted suicide. Suicide, especially in old age, is often viewed as a strategic, rational decision. In contrast, we argue that the suicidal crisis often escalates unexpectedly. Catastrophic choices follow a failure to consider present experiences in the context of prior knowledge and values.
