"I am currently a Project scientist in Massimo Vergassola's lab at UCSD. After studying soft matter physics in Paris, I moved into the physical/quantitative biology field for my PhD with Didier Chatenay. I then joined Massimo Vergassola's group in the Pasteur Institute (Paris) for my post-doc. As the lab relocated to San Diego, I felt that I could use some sun in my daily life and squeezed into one of the boxes. I have been developping and conducting experiments on bacterial chemotaxis and adaptation. More recently optimal strategies for soaring/gliding has piqued my interests. You can find a tiny bit more here."

"I am currently a postdoctoral fellow in Massimo Vergassola's group at University of California, San Diego where our lab moved from Institute Pasteur, Paris. With a background in theoretical physics and a strong interest in biological questions, I try to work at the boarder of those two disciplines."

"After my undergraduate in engineering physics from IIT Bombay, and a brief stint exploring bacterial cell physiology, I joined Massimo's group in April, 2014. My current interests include understanding how certain biological organisms navigate complex, turbulent environments. Particularly, I'm interested in understanding the thermal soaring of birds and the olfactory searches of insects. The underlying theme is to figure out how living beings under strong selective pressure solve the general exploration and exploitation trade-off that constitutes most navigation problems in uncertain environments. To answer these questions, we collaborate with experimentalists and use modern tools from machine learning and the physics of turbulent transport to model decision-making in noisy conditions. From a more theoretical viewpoint, I'm also interested in extracting general features of optimal search strategies in uncertain environments and developing simple approximations to otherwise complicated optimal policies."

"I am a Phd candidate in physics at the University of Milan (Italy), where in 2012 I obtained my master's degree. Since 2013 I have been several times a visiting graduate students in Massimo Vergassola's group, now at the University of California, San Diego. I am interested in neurobiological problems, which I approach with methods from theoretical physics. At the moment, my main projects focus on grid cells and on somatosensation. Grid cells are neurons thought to be at the basis of spatial cognition. I am investigating the effect of functional constraints on the underlying neural circuit. Somatosensation is based on specific types of neurons activated by mechanical stimuli. I am studying how the ionic channels of these neurons are gated by external forces and which is the role of the tissue mechanics in the process."
