Short bio

I did my integrated Masters and Ph.D. degree from Tata Institute of Fundamental Research, Hyderabad. I studied the collective behaviour of living and active matter using theoretical and computational tools.

Afterwards, I was a postdoctoral researcher at the Department of Living Matter Physics, Max Planck Institute of Dynamics and Self-Organization, Goettingen, Germany.

There, I focused on nonreciprocal interactions in living and active matter.

Research interests and hobbies

The lack of time-reversal symmetry and detailed balance in living and active matter allows for dynamical phases forbidden in equilibrium statistical mechanics.

My research focuses on building theoretical and numerical frameworks governing these non-equilibrium states.

I use analytical tools and large-scale numerical modelling to connect microscopic irreversibility and macroscopic self-organisation.

Beyond work, I pursue whatever piques my interest.

Complex Interactions in Living and Active Matter

Interactions at the extreme scales of physical reality are governed by the fundamental forces. At the smallest scales, subatomic particles, atoms and molecules interact through electromagnetic, strong, and weak nuclear forces. On the other end, gravity, in the Newtonian description, dominates the dynamics of planets, stars and galaxies.?

Life exists on the intermediate scales of reality. From molecular motors to massive cyanobacteria blooms, life constantly consumes energy to run, repair, and reproduce, operating far out of equilibrium.Living matter falls into the broader class of active systems that are composed of individuals, each consuming energy and dissipating it.

Interactions in living and active are mediated by numerous complex mechanisms such as chemical signals, sensory inputs, and the environment-mediated couplings (see figure). Complexity not only emerges naturally in living systems, but life also harnesses it to enhance adaptation and survival. Complex interactions, in general, break the Action-Reaction symmetry which drives global oscillations, emergent order, and chaotic states.

The central focus of my proposal is to investigate the origin and consequences of complex interactions in living and active matter. I will use the tools from non-equilibrium statistical physics to understand their consequences on the collective behaviour in such systems.
