Kort presentation
Vår ambition är att leda en avancerad forskning som kombinerar syntetisk organisk kemi, cell- och molekylärbiologi och preklinisk forskning för translationell medicin. Vi har ett internationellt team av forskare med komplementära skickligheter och vi letar alltid efter ambitiösa forskare (studenter och postdocs) med passion för science. För mer information om vår forskning, besök vår hemsida.

Oommen Varghese is an Associate Professor and University Lecturer at the Department of Chemistry, Ångström laboratory in the Polymer Chemistry program. Since 2011, he is a group leader at the Translational Chemical Biology laboratory and leads an independent research in biomaterial science, regenerative medicine (bone tissue engineering) and nucleic acids therapeutics. He has a state-of-the-art research facility that combines facilities to perform organic synthesis as well as cell and molecular biology. His interdisciplinary research team comprises of Ph.D. students, postdocs and masters students with exceptional skills in cell biology and synthetic chemistry. Currently, he is developing chemically modified nucleic acids (engineered plasmid DNA, short interfering RNA, and microRNA) that has the potential for clinical translation as it addresses some of the major bottlenecks in the field. Biomaterial research combined with nucleic acids therapeutics and regenerative medicine is the highlight of his research.
