I am currently a Tenure-Track Associate Professor at SJTU.
I received my PhD from Penn, and did my postdoc at Emory.

@aapahlavan Amir, congratulations!

Our work on JFM is featured on GSNP image of the month.

[@APS_DSNP @aps_dsnp]

The results are in! This month we are featuring Dr. Ranjiangshang Ran, for their work on "Poincaré map of the chaotic flow colored by the trajectory rotation average (TRA)."

Nice job @rrjs29!

Bacterial rheotaxis is ENHANCED in non-Newtonian fluids! In collaboration with @AJTM_M, Albane Thery, and non-Xers. Read about our experiments and simulations in our new PNAS manuscript at https://t.co/ZdznEn12UW @MEAM_Penn @PennEngineers @apsfluiddynamic @ApsDsoft @SoRheology

@mn_alipour @aapahlavan @apsfluiddynamic @YaleEngineering Great work, Mobin!

@burtonlab @apsfluiddynamic Thank you, Justin!

Thanks to @JFluidMech & Jeff Guasto for highlighting our work on the interplay of bacterial activity and Lagrangian coherent structures in 2D flows - it leads to Bacterial Barriers | Journal of Fluid Mechanics | Cambridge Core - https://t.co/poFUjLJmwB with @rrjs29

Hu et al. shows that successful dynamic large-eddy simulation models in turbulent flows hinges on the principal directions of the resolved strain rate tensor. By minimizing the Germano-identity error along fewer components, effective modeling is achieved! https://t.co/ND0Eqo2L1I

Bacterial Barriers (Part 1): New manuscript with @rrjs29 in @JFluidMech shows how interactions between swimming bacteria and flow elliptic Lagrangian coherent structures @GeorgeHallerETH form Lagrangian vortex boundaries (i.e., mixing barriers). See it at https://t.co/gzCvrx61Sg

How does particles settle in the presence of bacteria? In this new JFM article https://t.co/FRvuGferp8, we show that particle-bacteria interactions can lead to bioconvection patterns even in the dilute regime. With @pradeep_shravan, @dougsjunkdrawer, Bryan Maldonado, and @rrjs29

[Paulo E. Arratia @ArratiaPaulo]

How do swimming microorganism interact with flow currents/structures? Using a flow cell, we show that Lagrangian vortex structures (following @GeorgeHallerETH) enhance transport barriers by "expelling" swimmers. Check it out https://t.co/mXtvutq5ad Beautifully done by @rrjs29
