What's your background?
I am an interdisciplinary physicist with experience in complex systems, quantum machine learning, and cognitive science.
What's your role at LRC?
I am using tools from complex systems and modern cognitive science to investigate biological complexity, life as information and how scientists can discover regularities we call "laws of nature"---a kind of reverse-engineering of science. I hope this can help us develop a more scientific and powerful approach to artificial intelligence and to tackle some big questions in science and society.
What trend, breakthrough or discovery are you most excited about?
I am delighted to see the growing interest in the combination of first- and third-person methods for the investigation of the mind and its physical correlate. I am convinced this can provide unprecedented insights to help us tackle some big questions in science, build superior technologies, and develop a less fearful and biased, more socially and environmentally conscious society.
I am currently focused on understanding the origin of biological complexity, life as information, and the potential synergies between biology, AI, and physics. I am using analytical and computational tools to investigate the origin of biological complexity in protein interaction networks, which essentially underpin nearly all biophysical and biochemical aspects of known life. I am also interested in using the tools of modern cognitive science to understand life as information and investigate "scientific intelligence" by modeling scientists as biological/cognitive systems learning about the environment they inhabit.

As a Research Scientist at the NASA Quantum Artificial Intelligence Lab, John helped advance the field of quantum machine learning by contributing to successfully train, for the first time, a quantum annealing computer to generate, reconstruct, and classify images of hand-written digits. John earned a PhD in ICT-Physics at the Polytechnique University of Turin, Italy. His thesis work in Ricardo Zecchina's Microsoft Research theory group focused on the development of message-passing algorithms inspired on the physics of disordered systems for solving combinatorial socio-economic problems. Afterwards he worked as a posdoc with Alan McKane and Tobias Galla at the University of Manchester, combining tools of non-equilibrium statistical physics and agent based models to investigate socio-economic and ecological systems.
