Huvudintresse är neurohormonella reglerlekanismer för kontroll av blodtryck
och hjärtfunktion med fokus på strukturella förändringar av blodkärl vid
till hypertoni, hypertensiv hjärsjukdom, neuroendokrina reglermekanismer vid
hjärtsivkt och hur hypertoni kan leda till kronisk hjärtsvikt. Det
sympatiska nervsystemet och renin-angiotensin-aldosteronsystemet är av
