Biography
Associate Professor (Docent) Irena Loryan is a Senior Lecturer in the translational Pharmacokinetics-Pharmacodynamics (tPKPD) group in the Department of Pharmacy, Uppsala University, Sweden. She received her M.D. in 2001 and Ph.D. in pharmacology and biochemistry in 2007 from Yerevan State Medical University, Armenia. She then from 2008 to 2011 worked as a post-doctoral fellow at the Division of Pharmacogenetics at the Department of Pharmacology and Physiology, Karolinska Institutet (Prof. Magnus Ingelman-Sundberg Lab). From 2011 to 2013, she worked as a post-doctoral fellow at the Department of Pharmaceutical Biosciences, Uppsala University (Prof. Margareta Hammarlund-Udenaes Lab) in collaboration with Janssen Pharmaceutica, Beerse, Belgium. Since 2013 she has been a researcher and since 2021 a PI in the tPKPD group. Her current research interest focuses on neuropharmacokinetics, implying a mechanistic understanding of drug disposition in central and peripheral nervous systems involving passage across CNS and PNS barriers, distribution within parenchyma and elimination processes in health and disease.
