pharmaceutical sciences

Mashaghi made the first observation of direct
DnaK function and made a discovery that, according to Ans Hekkenberg, "overturns the decades-old textbook model of action for a protein that is central for many processes in living cells".[3] He and his co-workers found that chaperone DnaK can recognise natively folded protein parts and thereby promotes protein folding directly. Furthermore, the lab was the first to use optical tweezers to study folding of a single protein molecule in a cytosol, revealing the collective contribution of chaperones to folding.[4] Inspired by single-molecule analysis of biopolymers, Mashaghi and his team developed a topology framework, termed as circuit topology, which enabled studying folded molecular chains, beyond what knot theory can offer.[5] The approach allows for topological barcoding of proteins and cellular genomes for medical applications.[6] [7]
Mashaghi also contributed to others areas in biophysics and bioengineering including
hemorrhagic shock syndrome, and later extended the applicability of the platform to various viral haemorrhagic syndromes.[11] Ebola and similar viruses pathologically alter the mechanics of human cells, which is recapitulated in organ chip models. Moreover, the Mashaghi team developed optical tweezers and acoustic force spectroscopy based assays to probe such mechanical alterations at the single cell level.[12]
Mashaghi is also active in interdisciplinary research in
medical diagnostics; this unprecedented link between physics and medicine may allow for early and efficient diagnosis of certain diseases.[15]
During his academic career, Mashaghi has been affiliated with various institutions including
Nano Research
.
In 2018, Mashaghi has been named as "Discoverer of the Year" by Leiden University.[19] He is the recipient of several awards including an honorarium from American Chemical Society.
