I had a lot of fun transitioning from playing with fire ants 🐜 in my PhD to experimenting with live fish 🐠! Hopefully, my other projects during the postdoc, one on fish robots and another on the vibration of dead fish, will be out soon too.

The ladder formation could provide fish schools hydrodynamic benefits similar to the diamond formation, but further research is required. We are also excited about future research adopting our computer vision pipelines to research internal structures of other fishes and in nature

While fish constantly rearranged in three dimensions as we often observe in aquariums and nature, our data showed that fish prefer a vertically-staggered formation, we called "ladder formation". This formation has never been characterized before but appeared in 79% of fish pairs.

We recorded 3D fish schools swimming in uniform water flow for ten hours at a time and tracked their relative positions. We found that fish rarely adopt the classical diamond formation, less than 0.1% of the time!

A classical work in 1975 suggested that a planar "diamond" formation is the most hydrodynamically efficient, and still shapes the direction of the fish school research today. Half a century later, we decided to test this hypothesis, using cutting-edge computer vision techniques.

Have you ever wondered about how fish self-organize in 3D? Due to reasons, experimental and theoretical research of fish schools has been limited to planar formations.

I am excited to share that my first postdoc research paper is out!! Thanks to the great collaboration with Radhika Nagpal and Abigail Girma at @EPrinceton and @georgelauder, Yangfan Zhang, and Yu Pan at @HarvardOEB https://t.co/1yj5xfkOOQ

Easier to make connections: I could tap on the shoulders and ask my colleagues to grab a drink at conferences leading up to the job cycle. I can find mentorship from both male and female professors more easily.

Easier to find social fit: Everybody in my zoom interviews was male. Most on the search committee were male. Most departments had few women.

Thrilled to see this paper published @JoRheology! Check it out at: https://t.co/ISktfldL4T In it, we describe how changes in rheology influence the unsteady flow of viscoelastic polymer solutions through microfabricated porous media. Summary in the tweetorial below ⬇️

I'm thrilled to embark on this new chapter of my academic career at @TuftsUniversity . I look forward to collaborating with researchers at Tufts and beyond to continue to advance the frontiers of robotics, biomechanics, and collective behavior.

Our goal: robotic swarms capable of adapting to and exploring unstructured underwater ecosystems, from coral reefs to kelp forests.
