About me
I've studied signal processing engineering
at Grenoble INP before discovering
synthetic biology thanks to the iGEM competition in 2011. Following
this I decided to re-orient myself and finished my Master's working
on noise in metabolic feedback loops with Guy-Bart Stan and
Diego Oyarzún at Imperial College. I then started a PhD
with Pascal
Hersen and Grégory Batt at Université Sorbonne Paris Cité in 2012
during which I worked on real-time control of a genetic toggle switch.
After graduating, I joined the lab of Mary Dunlop at Boston
University as a post-doc in 2018 and have been working on a range
of projects from control of gene expression to label-free Raman
imaging, image analysis, and antibiotic resistance.
My research interests are broad, but can be grouped
together as quantitative approaches for the study and control of
the dynamics of cellular processes. I have applied techniques from
control theory, machine learning, optics, and synthetic biology to
the study of antibiotic resistance or biofuel production in
single bacteria. In the last few years I have been following the
sustained progress in deep learning as I find it particularly
well-suited
to identify patterns in complex and noisy biological datasets,
especially as experimental
methods keep increasing in throughput. In particular deep
reinforcement learning,
which lies at the intersection of machine learning and control
theory, is a promising
avenue of research for AI in biology, as these methods can navigate
complex landscapes efficiently. Currently, I'm developing
interfaces bridging cells
and machines to harness these advanced algorithms, while exploring
the unique challenges that they face in biological contexts.
