How I became interested in Psychology

I had an excellent 101 course. Then, I started working with Dr. Michael Lambert at Brigham Young University and became involved in his research. From that, I pursued graduate training in clinical psychology.

Current Research and Professional Projects

I am currently studying the impact that outcome measures and other factors can have on the therapists’ judgment of client change and subsequent treatment decisions. I am also interested in applying research from the field of judgment and decision making to issues in clinical psychology.

  • Therapy outcome and process research
  • Clinical judgment and decision making
  • Client deterioration (getting worse) in therapy
  • How therapists determine client progress
  • Clinical use of therapy outcome measures
