My research programme evolves around how toxic agents ("aggregates") that are associated with cell stress and neurodegeneration can be counterbalanced by the molecular recycling machines ("proteasomes") that are found abundantly in cells.

Read about my research to fight dementia in plain English.
Aggregation of misfolded proteins is a pathological process implicated in neurodegenerative disorders and dementia. While much research effort has focused on how aggregates are assembled, the reverse process of aggregate removal is less well-studied. Using advanced microscopy and cell biology approaches, my lab studies how proteasomes maintain cell homeostasis by targeting aggregates and how the ubiquitin-proteasome system is impaired in disease. Our recent results in vitro and in cells demonstrate that proteasomes restrict aggregate size and reorganise upon cell stress, assembling into foci around aggregates in a cytoskeleton-dependent manner. We are now focusing on the mechanisms underlying proteasome responses during aggregate formation in neurons, ultimately establish approaches to restrict and reverse dementia.
Our long-term goal is to identify distinct functions within the ubiquitin-proteasome system that will be amenable to therapeutic intervention at the different stages of neurodegeneration.

I (he/him) grew up in a small Nordic university town and have settled in the UK since undergraduate. Besides enjoying part of my postdoc fellowship in Boston in The Spirit of America, most of my time was spent in the nostalgic city of Cambridge. I am really thrilled to return to my alma mater and the innovative and diverse city of London.
Coming from a humble background, I have been immensely fortunate to have been guided by great mentors at various stages of my career. It is through their encouragement, as well as the unconditional support from my family, that I could pursue my goals without looking back.
When not busy in the lab, I enjoy racket sports, nature photography, tai chi (and others), chess (peak ecf 170, elo 1916) and beginner's Chinese calligraphy.
