About me

I obtained my doctoral degree from Department of Medicine Huddinge, Karolinska Institutet (KI) in 2013. Following my two year postdoc  I joined the  Department of Laboratory Medicine as Assistant Professor in 2015, where my research focuses  on multi-omics system biology approach to understand the disease control mechanism in a group of HIV-1 positive individuals who control viral replication without any therapy called Elite Controller.
