About us

Our research centers on the theory of complex systems and biophysics, applied to a broad spectrum of problems, mainly in the context of the physics of living systems. Our research is often done in collaboration with experimental groups. Key themes of our lab include mathematical modeling of cell growth and mechanics, both at the single-cell level and the population level, stochastic processes, disordered systems, and coarse-grained modeling of complex processes.

Yipei's paper on the stability of gene regulatory networks is now published:



Well done to Paul on his new paper on diffusive waves, showing when the continuum description is adequate and when it fails, with rather counterintuitive results:



A big congratulations to Jie on starting as a professor in Peking University! Jie's paper on the dynamics of gene expression, with surprising connections to statistical physics, is now in press in PRL (https://www.biorxiv.org/content/10.1101/2020.08.26.268722v1).  

New papers on phenotypic variability and more

December 29, 2020
Two new papers related to phenotypic variability:
This paper by Felix Barber, joint work with Andrew Murray and Jiseon, on the effects of asymmetric division and stochasticity on the population growth,  and this paper by Jiseon on the fitness effects of asymmetric segregation of cellular resources. 

Congratulations to Yipei on her paper on stability of gene regulatory networks in press in Nature Communications, and to Paul's paper on diffusive relays (together with Jiseon and Daniel Irimia at MGH) published in eLife.

Finally, Ariel's book is now available for purchase in digital format, and will be available in print in February (https://amir.seas.harvard.edu/thinking-probabilistically

Congratulations Dr. Guo!

Well done to Yipei on successfully defending her Ph.D., and best of luck on your next adventure at Janelia Farm! Yipei will soon be joining the group of Dr. Ann Hermundstad for her postdoc.
