"Understanding nucleation, growth, and phase evolution provides a basis for rational control of inorganic material formation." We investigate how inorganic materials nucleate, grow, and evolve under solution-based synthesis conditions. Understanding these processes is essential for controlling not only particle size and morphology, but also composition, crystallographic structure, phase stability, and defect formation. Our research focuses on identifying the chemical and structural factors that govern the formation of complex metal hydroxides and oxides, including precursor chemistry, hydrolysis and condensation, supersaturation, coordination environments, and phase transformation pathways. By connecting these fundamental processes with experimentally accessible synthesis parameters, we aim to establish rational and transferable principles for the controlled preparation of multicomponent inorganic materials. "Programmable layered frameworks offer precise control over composition, local cation environments, interlayer chemistry, dimensionality, and post-synthetic transformation." Layered metal hydroxides and oxides provide versatile platforms for inorganic materials design because of their compositional flexibility, structural adaptability, and accessible interlayer chemistry. Layered double hydroxides, hydroxy double salts, phyllosilicates, and layered titanates, in particular, offer versatile two-dimensional crystalline frameworks that accommodate diverse metal cations through distinct structural and coordination environments, enabling systematic control over chemical composition, local coordination, and the spatial distribution of metal cations. A major focus of our research is to understand how composition and layered structure govern cation incorporation, distributi
