Dr. Finsaas is interested in the phenomenon of separation anxiety, particularly as it is experienced by adults. Separation anxiety means impairing anxiety that arises in response to actual or impending separation from another person. It can be experienced by adults in the context of romantic relationships, for example, when a partner goes on a business trip. Sometimes, it shows up in the form of somatic symptoms (a stomachache before a trip), aggression (don't you dare leave me!), or incompetence (I can't do this without you). It is a relatively prevalent clinical problem--epidemiological studies show that about 1 in 15 adults will experience it in their lifetimes--and people who experience it fare more poorly in psychiatric treatments, both pharmacological and psychotherapeutic.

Her work in this area focuses in particular on how the ways in which one represents self versus other in the mind relates to separation difficulties, as well as on the measurement of separation problems. A current project includes developing a new tool to assess common modern ways of relating and regulating distance/closeness in relationships, namely, texting and social media use.

More generally, she works on questions of continuity and comorbidity of psychological disorders across development.

Finally, Dr. Finsaas teaches statistics and conducts research with a group of colleagues on interactions in linear regression. She has created two Shiny web applications (http://3dinteractions.com/ and https://mfinsaas.shinyapps.io/InteractionPoweR/) for researchers in the community to use.
