Helena Nordenstedt finished her medical degree at the Karolinska Institutet in 2007. The same year she defended her PhD thesis in surgery with Professor Jesper Lagergren as main supervisor. After medical internship (AT) she spent 6 months in 2009-2010 at Baylor College of Medicine, Houston, Texas, USA as a postdoc under the supervision of Professor Hashem El-Serag.
In 2012, after working as a physician in a district hospital in the eastern part of the Democratic Republic of Congo for Médecins Sans Frontières, she is currently working as an Assistant Professor in Global Health. Since 2016 she is a specialist physician in internal medicine, working half time at The Department of Internal Medicine at Danderyd University Hospital.
In October-November 2014 she worked as a physician in an Ebola treatment centre in Liberia, and in August 2015 in an Ebola treatment centre in Guinea, both missions for Médecins Sans Frontières.
After defending her thesis in 2007, "Gastroesophageal Reflux Disease: Etiological factors", Helena Nordenstedt started studying epidemiology of esophageal, stomach and liver cancer globally.
Since 2013 her focus of research has changed to Global health, still with an epidemiological basis, working closely with Professor Anna Mia Ekström.
In 2015 received a grant from The Swedish Research Council for a project on cardiovascular diseases in aging HIV patients in Uganda.
Lately Helena has been working closely with Karin Båge, Hans Rosling and other collegues, on a Massive Open Online Course (MOOC) in Global health.
Together with Anna Mia Ekström, since 2013, Helena is responsible for a 5-week elective undergraduate course in Global health, with 70-90 students each semester, who spend 2 weeks of the course in a low-income country like Uganda, Tanzania, Vietnam and Laos.
In 2016 she was responsible for the 2-week Non-Communicable Diseases, Injuries and Disasters course, which is part of the Master of Global Health at KI.
