Hi, my name is Ishant Tiwari and I am a Postdoctoral researcher at the Bhamla Lab at Georgia Tech, Atlanta. My Postdoctoral advisor is Saad Bhamla. I am currently studying various entangled and knotted systems, ranging from tangled fibers to knotted worms. I am fascinated by both the effects of topological complexity on the mechanical response of a system and how slender biological organisms might utilize knots and tangles for functional purposes. 

I did my doctoral work at IIT-Bombay in the broad area of experimental nonlinear dynamics, specifically, the dynamics of an ensemble of self-propelled particles. My Ph.D. was supervised by Punit Parmananda.  

I finished my Masters in Physics at IIT-Bombay with an experimental thesis on the general topic of Stochastic Resonance, studied using an electrochemical system involving the dissolution of Iron in Sulfuric acid.

My Bachelors in Science with Physics(Hons.) was from S.G.T.B. Khalsa college, University of Delhi. 

Since my master's in Physics, I have worked or am working on the following subjects, in arbitrary order:-

• Organismal Biophysics

• Entangled systems and Knot formation

• Active matter and its ensemble dynamics

• Stochastic Resonance

• Synchronization

• Oscillation Quenching

• Agent-based epidemic modeling

Ongoing Projects

• I am currently studying entangled systems (biological and artificial). Specifically, I am trying to understand the dynamics of fiber extraction from a tangled filament and what role topology plays in it. 

• I am fascinated by topological complexities (such as knots) that appear in nature across a variety of length scales and am currently exploring some of these systems. 

• I am also interested in understanding the peculiar interfacial dynamics of a water-walking insect from the genus Rhagovelia.

• I am also trying to understand the physical aspects of the worm blobs formed by Tubifex spp. and the California Blackworms Lumbriculus variegatus. I am fascinated by complex behaviors that emerge when a collection of active agents comes together.
