I am a results-oriented manager, scientist, and team leader with 12+ years of industry experience backed by strong scientific expertise and a publication record in the field of in vitro toxicology. Actively working in academia since 2019. 

My main scientific interest is in tissue engineering of reconstructed in vitro 3D organotypic models that are used for in vitro toxicity testing.  I have unique expertise in the development of in vitro assays with 3D tissue models, their validation and implementation into the regulatory toxicology and OECD Test Guidelines. 

I've been a part of many exciting scientific as well as business projects and gained invaluable managerial and business skills.
