Welcome to the Supramolecular Chemistry Lab

We are a multidisciplinary research group focused on supramolecular chemistry, smart materials, and biomimetic systems. His work lies at the interface of organic chemistry, materials science, and chemical biology, with a central aim to emulate nature’s design principles for the creation of functional and responsive molecular systems.

A key thrust of
our research is the development of hostguest assemblies using cucurbiturils, which are leveraged to construct complex peptide-based networks, dynamic self-assemblies, and life-like systems. These structures are explored for their potential in drug delivery, biosensing, and stimuli-responsive materials. The group is also pioneering the use of chemical clocks (pH- and redox-based) to construct transient, time-programmed assemblies, pushing the boundaries of anti-counterfeiting technologies by introducing time as an encryption dimension.

In addition, our lab is actively involved in the development of smart windows, stretchable motion sensors, and soft actuators, contributing to the growing field of adaptive, multifunctional materials.

We are passionate about collaborative science and the translation of fundamental chemical insights into practical applications.
