I apply principles from cognitive and social psychology to answer questions about suicide and self-injury among youth. How can we more objectively assess suicide risk? Do certain patterns of thought place individuals at greater risk of self-harm? How do cognitive and other types of risk factors vary between adolescents and adults? To answer these questions, I conduct research through laboratory experiments, hospital-based data collection, and meta-analyses.
