My PhD was supervised by Prof Nico Bruns at the Adolphe Merkle Institute, University of Fribourg, Switzerland. My work focussed on the fabrication of cell inspired polymer nanocontainers that displayed ON-OFF biocatalytic activity in presence of external stimuli such as light or hydromechanical stress as well as polymerisation-based diagnostics for blood borne diseases. Moreover, a diagnostics company was spun-out from my PhD receiving over 1M USD in funding.

I joined the group of Prof Molly Stevens at Imperial College London as a Postdoctoral Fellow (Swiss National Science Foundation Early Postdoc Mobility Fellowship and Marie Skłodowska Curie Actions Individual Fellowship) to study the implementation of life-like properties to a family of aqueous polymer and enzyme ensembles through non-equilibrium feedback communication processes.

In September 2023, I joined the Department of Chemistry at Queen Mary University of London as Lecturer, where I lead a research group focussing on the synthesis of polymer-based artificial cells as experimental models to understand physicochemical parameters that underpin biological phenomena and to achieve novel technologies at the Living/Non-Living Interface.

Research

Research Interests:

One of the most intriguing questions at the interface between chemistry and biology is “how did inert matter transition into living matter?” Though life on Earth is mainly composed of lipids, proteins, and nucleic acids it is possible that in other parts of the universe –which harbour very different physicochemical conditions– life could be composed of different building blocks. For example, Titan –which is one of the moons of Saturn– presents very similar properties to Earth: it presents seas, lakes, and rivers although instead of being composed of water, they are composed of liquid ethane and methane, which are carbon sources. This poses another intriguing question for synthetic biologists: “can we synthesise living matter from alternative building blocks to Earth life (lipids, proteins, and nucleic acids)? Or at least, “can we make artificial ensembles that display life-like properties?” These systems would have to be dynamic in nature and be capable of harvesting energy from the environment to display vital functions such as metabolism, growth, replication, or even (chemical) cognition.

By combining expertise in polymer chemistry, enzymology, nanotechnology, and organic synthesis our group is investigating the synthesis of artificial cells that display life-like functions which will provide understanding of physicochemical parameters that are required for life, insights into the origins of life on Earth – and maybe some other parts of the universe–, and to provide novel tools for living cell manipulation. The technologies can also be applied for drug delivery, controlled catalysis, and novel diagnostics platforms.
