About me
My basic degree is doctor of veterinary medicine, and I graduated from SLU in 2003. After working as a veterinarian a few years, I decided to get a PhD and joined an EU project, which aimed at producing artificial spider silk for medical applications. The project started with me going on an “adventure trip” to South Africa to collect 100 spiders in the wild. Since then, I am fascinated by this impressive material, and the spiders that produce it.
In 2007 I received my PhD, and soon after we started the company Spiber Technologies AB to commercialise our research findings. I was CEO from 2008 to 2012. In 2011-2017 I worked as an Assistant Professor at Karolinska Institutet, where I still work part time, and as an Extension Specialist/Senior Lecturer in Translational Medicine at SLU. Since 2018 I am professor of veterinay medical biochemistry at SLU and in 2024 I was appointed Wallenberg Scholar.
Research and area of expertise
My research area and area of expertise include biomimicr, bioinspired materials, regenerative medicine, molecular biotechnology and medical biochemistry.
We can artificially synthesize spider silk fibers that are as tough as native spider silk fibers which makes them highly interesting as replacements for petroleum based (plastic) fibers. Our production method is biomimetic, meaning that it is completely water based and void of denaturing chemicals and high temperatures. We focus basic studies of the silk producing organs in spiders, on scaling up the production of artificial spider silk, develop fibers for the textile industry and use fibers and hydrogels for project related to regenerative medicine (tissue repair).

In another project we study a specific part, NT, of the spider silk protein, which increases the solubility of the spider silk proteins when they are stored in the spider’s silk glands. The solubility enhancing properties of NT apply also when NT is fused to other proteins with low solubility. Therefore, we use NT to produce protein drugs, which today are difficult or impossible to manufacture.
The spider silk proteins we produce form transparent hydrogels when the temperature is increased to 37 degrees. This discovery is now being developed further in projects related to injectable materials and as aplatform for immobilizing different proteins in a 3D matrix (Arndt et al. Nat Commun. 2022; Arndt, Chatterjee et al. Adv Funct Mater. 2023)

Current research
My research has several main focuses:
1. To make artificial spider silk replicas.
2. To use spider silk to regenerate damaged tissue and to be able to culture stem cells under defined conditions
3. to use Nature’s own solubility increasing domain (NT) to develop poorly soluble proteins (drugs).
4. to explore how spiders spin their silk and make better biomimetic silk fibers and bioinspired solutions for the life science industry

Research problems
How does the spiders' silk glands manage to produce extreme amounts of proteins and store them without encountering problems associated with premature aggregation?
Can we spin artificial spider silk fibers with the same mechanical properties as the natural spider silk fiber?
Can artificially produced spider silk be used as implants to replace damaged tissues and organs?
Can NT be used for the production of valuable and aggregation prone proteins with low solubility?

Extension
Spider silk has long been used in folk medicine. I aim to use spider silk in the treatment of diseases and injuries, for which there is no or poor treatment options available due to the lack of suitable materials. I also work to facilitate production of protein-based drugs together with a pharmaceutical company.
By close collaborations with national and international partners in industry and at universities, my research will benefit society at large.
Our research has been on public display at exhibitions at Nobel Museum in Stockholm, Arbetets Museum in Norrköping, Skansen Aquarium (Skansen-Akvariet), Sweden, the World Expo 2010 in Shanghai, and Paris Natural History Museum, 2011-2012.
