Research at a Glance

A full research program, connected by one design logic

The group's current program connects hard-carbon storage, transparent conductors, defects and doping, and electrolyte/interface chemistry through the same design logic: identify the mechanism, test its realism, and turn it into a rule that can guide experiments.

Inverse materials design

From target property to mechanism, realism check, and design rule

The group does not treat computation as candidate-list production. The central task is to connect structure, chemistry, and electronic response to experimentally testable mechanisms.

Material systems

Hard carbon / Na-ion storageinterlayer spacing, pores, oxygen chemistry, plateau capacity
Gapped metals / transparent conductorsintrinsic carriers, off-stoichiometry, dielectric response
Defects / dopinglocal symmetry breaking, compensation, antidoping
Electrolytes / interfacesion pathways, solvent coordination, degradation mechanisms

Research engine

1 Function capacity, mobility, transparency, stability, response
2 Atomistic model structure, disorder, defects, interfaces, local chemistry
3 Mechanism what controls the property and why it changes
4 Realism check thermodynamics, kinetics, competing phases, observables
5 Design rule what to tune and how to test it experimentally

Calculation layer

DFT defect thermodynamics molecular dynamics ML potentials optical response post-analysis tools

Outputs

  • mechanistic explanation rather than a list of candidates
  • falsifiable signatures for experiments and collaborators
  • design knobs for composition, structure, defects, and interfaces

For Us, Inverse Design Means

Start from function, then find the physics that can survive reality

The group avoids treating computation as candidate-list production. The aim is to identify the mechanism that controls a property, test whether it is realistic, and convert it into a rule that experimental partners can use.

Function first Begin with a measurable target such as plateau capacity, transparency with conductivity, ion mobility, defect control, or dielectric response.
Real structure matters Disorder, local symmetry breaking, pores, interfaces, off-stoichiometry, and intrinsic defects are treated as design variables rather than nuisance terms.
Theory must be testable A useful prediction should explain what to tune, why it works, and which experimental signatures would prove or falsify the mechanism.
Tools follow the question DFT, defect thermodynamics, optical-property calculations, molecular dynamics, machine-learned potentials, and data analysis are combined only when they clarify the mechanism.

Current Project Spine

What the group is building now

Since 2024, the public research direction is organized around three connected threads: carbon anodes, gapped metals, and Casimir-Lifshitz physics driven by real optical properties.
