About me

I am a researcher at the Institute of Environmental Medicine at Karolinska Institutet with a background in genetics, cancer and toxicology. In recent years, my main focus has turned towards development of Adverse Outcome Pathways (AOPs) and New Approach Methodologies (NAMs), as well as their application in risk assessment and in safe and sustainable development of new technologies. Coupled to this focus, I also have a broad interest in making data Findable, Accessible, Interoperable and Reusable (FAIR). In addition to research, I function as coordinator within the Swedish platform for Nanosafety, SweNanoSafe, where I focus on communication, education and sustainability (e.g. Safe and Sustainable by Design, SSbD) aspects within nanosafety.

Ongoing projects and involvements:

Toward risk assessment without animals: Development of Adverse Outcome Pathways for lung cancer

PARC - European Partnership for the Assessment of Risks from Chemicals

HARMLESS - Advanced high aspect ratio multicomponent materials: towards comprehensive intelligent testing and safe by design strategies

Selected previous projects and involvements:

Teaching portfolio


I am course leader for the PhD course Human Cell Culture. Methods and Applications. (code 3127). I also lead course modules in the Master Program in Toxicology, including on bioinformatics and omics, as well as a workshop on toxicological high-throughput screening assays and data (ToxCast workshop). Furthermore, I provide a number of lectures both at KI and other universities and external courses in the areas of human cell culture methods, alternative (3R) methods, toxicogenomics and systems toxicology, bioinformatics, high-throughput screening approaches, data management (FAIR principles), Adverse Outcome Pathways (AOPs) and Safe and Sustainable by Design (SSbD).
