          Are you willing to be interviewed for 20-30 minutes to learn
          more about your perceptions and experiences of Trinity
          and Hartford? (We’ll buy you a beverage or pastry to compensate
          you for your time.)

          The entire process is voluntary and

          participate, enter your information below so that
          one of our student researchers can contact you
          to set up a mutually convenient time and place for an interview:
