Research Interests

I research mental health problems within the context of close relationships. I am specifically interested in the role that close significant others (e.g., friends, family members, romantic partners) can play in helping their loved ones recover from traumatic stress.
My broad research interests include:
  • the bidirectional relationship between social support and PTSD
  • Concerned Significant Other experiences
  • PTSD treatment and prevention
  • technology-facilitated research and intervention methods

  • PSYC 251: Intro to Behavioral Res Method

    A systematic study of the principles of research design and methods. Topics include scientific methods of descriptive, correlational, basic experimental, quasi-experimental, and single-subject approaches, issues of validity and experimental control, ethical considerations, and skills in accessing and using psychological literature, critical reading, and scientific writing using American Psychological Association style.

  • PSYC 260: Intro to Psychopathology

    This course offers a framework for understanding maladaptive behavior focused on the symptoms, causes, and treatment of a range of psychopathology, including anxiety, personality, mood, psychophysiologic, schizophrenic, and substance abuse disorders. Each disorder is considered through a comparison of biological, psychological, and sociocultural viewpoints on the causes and treatment of abnormal behavior. Current research issues as well as legal and ethical issues related to the assessment and treatment of abnormal behavior are discussed.
