Dr. Jacqueline Evans conducts research on investigative interviewing in its many forms, to include interviewing cooperative witnesses, interrogating uncooperative suspects, gathering intelligence from sources, and interviews in epidemiological investigations. In addition, her research addresses the ability (or lack thereof) to detect deception in a variety of contexts. Some of the variables/constructs Dr. Evans is currently interested in include: language proficiency, presence of a translator, and interviewee intoxication. Dr. Evans works on these projects with both graduate and undergraduate students. She hopes that findings will help to inform professionals in various legal, national security, and public health contexts regarding the most effective methods to use when engaging in an investigative interview and assessing interviewee credibility.
