Ariel Amir, Principal Investigator 

Office: Pierce Hall 321

Ariel Amir grew up in Israel and received his B.S. from Hebrew University and his M.S. and Ph.D. from Israel’s Weizmann Institute of Science. In 2011, he came to Harvard University as a Junior Fellow, and in 2014, he joined the Harvard Paulson School as Assistant Professor of Applied Math and Applied Physics. His research centers on the theory of complex systems, which he applies to problems from physics, materials science, and living organisms, often in collaboration with experimental groups. He emphasizes the need to recognize unifying principles that cross disciplinary boundaries. For example, he has shown that the behavior within a class of different glassy systems is universal, and is currently working on extending these tools to systems not typically viewed as “glasses.” Similarly, his research in biophysics employs dislocation theory—widely used to analyze mechanical properties of solids—in modeling bacterial cell wall growth. Methods from statistical mechanics allowed him to address the problem of how microorganisms such as bacteria control the size of their cells. Current work in the group is focused on various aspects of disordered systems and stochastic processes, including structural coloration (generation of colors by means of specific structures at the sub-micron scale rather than pigments), shape regulation in microorganisms and the physics of glassy systems. 

Jie Lin, Postdoctoral Fellow 

Office: Pierce 314

Jie is generally interested in statistical physics of biological systems and soft matter. He has been working on different topics including population growth, cell size regulation, driven amorphous solids, and jammed packings.


Ethan Levien, Postdoctoral Fellow

Office: Pierce Hall 328B

Ethan is interested in understanding stochastic processes with applications in biological systems. He has worked on problems in chemical reaction network theory and diffusion in random environments. Most recently, he has been studying bet-hedging in microbes.


Ahmad Zareei, Postdoctoral Fellow


Ahmad is generally interested in fluid dynamics, nonlinear waves, continuum mechanics, and dynamical systems. He is currently working on modelling flow in porous media using random resistor networks and also modelling dynamics of Euler's disk with a focus on dominant dissipation mechanism due to purely elastic waves radiation.

Nitin Upadhyaya, Postdoctoral Fellow 
Current: Flame University, Pune



Po-Yi Ho, Graduate Student

Current: Huang lab, Stanford University 

Po-Yi's research focused on understanding how cells grow and divide. How do cells regulate and coordinate the timing of their divisions and the replication of their chromosomes? What is the stochastic nature of these processes, and how are they controlled?


Felix Wong, Graduate Student

Current: Collins lab, MIT

Felix's research focused on cell mechanis, and in particular on understanding the subcellular organization and regulatory processes needed for bacteria to maintain a robust shape. He was addressing this question using tools from differential geometry to coarse-grained numerical computation. 



Felix Barber, Graduate Student 

Current: Rojas lab, NYU

Felix was trying to understand the regulation of cell size through a combination of theoretical and experimental approaches. He was working on this problem in budding yeast, and had a joint supervision by Andrew Murray.
