• Team of 15 faculty from Psychiatry, Computer Science, and Business
  • Twitter scrapes to detect increased incidences of suicide risk using a validated phrase dictionary from mental health and suicide experts. The data is  structured using natural language processing, and then analyzed by econometric experts from business.
  • Project funded by direct grant from Vice Provost for Research, Johns Hopkins University
  • Other projects being planned in a general survey of the population on depression, anxiety, and other milder forms of mental conditions, in collaboration with a team from Chile and Spain.
  • Collaboration with Center for the Business of Health on the economic consequences of the mental health impact of COVID-19. Individuals that develop or have worsened mental health conditions as a result of COVID-19 confinement and job loss may enter the chronic unemployment rolls, increasing the long-term deadweight loss to economic welfare.
