Jordan L. Shivers

I am a Schmidt AI in Science Postdoctoral Fellow at the University of Chicago, where I am jointly mentored by Suri Vaikuntanathan and Aaron Dinner. I am broadly interested in the physics and engineering of active soft and biological matter, and I tackle problems in this area using a combination of computer simulations, theoretical soft matter physics, and machine learning techniques, often in collaboration with experimental groups.

I received a Ph.D. in Chemical and Biomolecular Engineering from Rice University in 2022, under the supervision of Fred MacKintosh. There, I used theoretical and computational tools from soft matter and statistical physics to model the mechanics and dynamics of disordered biological materials. In 2016, I received a B.S.E. with honors in Chemical and Biological Engineering from Princeton University, where I worked with Cliff Brangwynne to develop a novel experimental technique to study the dynamics of biological condensates in developing organisms.

Research interests
  • statistical physics of soft, active, and biological matter
  • mechanics and dynamics of living cells and tissues
  • machine learning for physics and engineering
  • metamaterials and trainable matter

I’m always excited to discuss new ideas and potential collaborations. Feel free to reach out if you’re interested in my research!
