Dr Alberto Ospina Stella

Adjunct Associate Lecturer

PhD (molecular virology), M.Sc. (molecular medicine), B.Sc. (molecular biotechnology).

Medicine & Health
The Kirby Institute

Alberto obtained a B.Sc in molecular biotechnology (2012) and a M.Sc. in molecular medicine (2014) from top-rated universities in Germany.  He then completed his PhD at UNSW (2019) and continued his work as postdoctoral research scientist at the Kirby Institute, working on HIV host-pathogen interactions and gene therapy cure approaches for HIV infection.  Since March 2020 (first COVID-19 wave in Australia), Alberto was recruited to work full-time on SARS-CoV-2 (novel coronavirus) research, as part of our institute’s rapid response strategy to the pandemic.
