Forskningsområden

Jag studerar hur hjärnan hanterar rädsla och ångest. Speciellt intresserad är jag att förstå hur genetiska faktorer bidrar till hjärnfunktion som styr rädsla och ångest.

Forskning

Betydelsen av arv och miljö för känslomässiga processer i amygdala.

Hur påverkar genetisk risk för psykiatrisk sjukdom genuttryck och hjärnfunktion vid stress?
