RESEARCH PROFILE

From soft-matter theory to complex systems.

I am a theoretical physicist working across soft condensed matter and complex systems. My research combines analytical theory and computational modeling to understand how structure, interactions, and constraints give rise to collective behaviour. In polymer and soft-matter systems, I study molecular topology, chain correlations, and phase behaviour using statistical field theory and fluctuation methods [work] [work] [work] [work]. I also study diffusion, phase behaviour, and collective dynamics in heterogeneous and nonequilibrium systems [work] [work] [work]. In parallel, I develop computational methods for inverse design and combinatorial optimization [work] [work]. With additional training in computer science, I am particularly interested in applying statistical-physics ideas to complex networks [work] [work], and in exploring neural networks and artificial intelligence as complementary tools for physical modeling and optimization.

RESEARCH THEMES

Theory connecting structure, topology, transport, and complex systems.

01

Polymer field theory

Develop SCFT for polymers with transformable topology [work] and RPA descriptions of chain correlations and microphase separation [work]. I also apply numerical field methods to nanoparticle assembly [work] and orientation in block copolymers [work].

02

Thermodynamics & dynamics in porous media

Develop statistical theories for hyperuniform structure formation under attractive interactions [work] and for diffusion in hyperuniform porous media [work]. I also use eigen microstate theory to characterize collective modes in polymer diffusion [work].

03

Combinatorial optimization & inverse design

Develop simulated bifurcation methods for large combinatorial problems, from polymer sequence design [work] to traffic signal optimization on real networks [work]. The same statistical physics framework is adapted to molecular and urban systems with discrete variables, complex constraints, and no analytical gradients.

04

Selected collaborative studies

Contribute theoretical analysis to entropy effects in exciton dissociation and charge transport [work] [work], and to Onsager theory for phase separation and interfacial behaviour in driven mixtures [work]. I also contribute to model analysis in transport networks [work] and analysis of large literature datasets on organic photovoltaics [work].
