Jag leder en forskargrupp med huvudsakligt fokus på utveckling av metoder för medicinsk ultraljudsavbildning, med tillämpningar på kärl och skelettmuskulatur. Fokus ligger på signal- och bildanalys med spatiotemporala statistiska och djupa faltningsnät metoder tillsammans med skräddarsydd avbildning där vi har programmerbara ultraljudssystem (Vantage 256, Versonics, samt SonixTouch inkl DAQ unit, Ultrasonix).

Övriga kompetenser inkluderar elektromyografi (högdensitets multikanals yt-EMG), near infrared spektroskopi (NIRS), och eHälsa.

Examina: Docent Medicinsk teknik (2012), Tekn Dr Medicinsk Teknik (2007), Civ Ing Teknisk Fysik (2002).
