About me

Adjunct lecturer at the Division of Speech and Language Pathology since 2011 and employed by the Karolinska University Hospital at the Function Area of Speech and Language Pathology (SLP).

My main ​​clinical and research interest is assessment and treatment of patients with different types of voice disorders. Developing areas are occupational voice disorders and voice ergonomics and voice treatment for people with gender dysphoria. I am a member of the interdisciplinary "Gender-team" at Karolinska University Hospital.

Doctoral exam 1994 at the Karolinska Institutet, the title of the dissertation "Vocal fold closure during phonation - physiological, perceptual, and acoustic studies". Associate Professor at Karolinska Institutet in 2006. Fulbright Scholar at Columbia University in New York 1983-1984.

Education

Coordinator for the course "Voice, speech and communication disorders 2" (3 credits) at the study program in Speech and Language Pathology (SLP) at KI, and teacher/supervisor of students at clinical placements.

I also teaching physicians (ST-courses) about objectives and scientific evidence for voice therapy given to patients different voice disorders.

Coordinator for courses at advanced level, free-standing courses, the latest "Voice and speech in transsexual individuals - assessment and intervention" (7.5 credits), the next planned "Voice disorders and voice ergonomics" (7.5 credits).

Other teaching activities are supervision of degree projects for the study program in SLP and Master’s degree (30 credits) and

Supervistion of doctoral students. Main supervisor for Annika Szabo Portela and co-supervisor for Joakim Körner Gustafsson and Peter Pabon.

I participate in teacher exchange with the University of Sheffield in England and the University of Copenhagen in Denmark within the ERASMUS program.

Research description

My two research areas are "Occupational voice disorders" and "Voice and speech in people with gender dysphoria".
 
Voice usage during work and leisure is studied in people with vocal demanding work, e.g., teachers, who are at risk to develop severe hoarseness and vocal fatigue because of excessive load on the vocal folds. A portable voice dosimeter, Voxlog, has been designed to measure the speaker's voice activity and level of the environmental noise during a week's time. Voice data is stored in a database from which the covariance between voice usage, noise level and self-perceived voice problems can be identified. The results will create a basis for voice ergonomic recommendations.
 

Research about "Voice and speech in people with gender dysphoria" focuses on transwomen who are assigned male gender at birth but identify themselves as female. Many transwomen need voice therapy to adapt the male voice to match the patient's gender identity as female. Some patients also need additional pitch-raising vocal fold surgery. Treatment outcome studies are ongoing and planned for the patient group transwomen.
