What We Do


The group has established a strong presence in the scientific community through a robust publication record and the successful acquisition of competitive research funding. It consists of a vibrant and diverse team of PhD scholars, postdoctoral researchers, and MSc students, fostering a collaborative and interdisciplinary environment for scientific inquiry and discovery.

To pioneer at the intersection of fundamental molecular theory and computational innovation, CTCC is dedicated to decoding the interesting un predicatble nature of the chemical bond. Our research focuses on the rigorous analysis of non-covalent interactions, aromaticity, and electronic structure to provide a definitive understanding of molecular behavior. By integrating traditional chemical intuition with emerging technologies in Machine Learning, Artificial Intelligence and Quantum Computing, we strive to advance the frontiers of catalysis, molecular recognition, and solvation dynamics. Our mission is to foster an interdisciplinary environment that empowers the next generation of scientists to bridge the gap between abstract theory and sustainable solutions in molecular materials science, energy science, drug discovery etc , ensuring a future grounded in molecular excellence.

Non-Covalent Interactions (NCI): Modeling and deconstructing weak interactions, specifically hydrogen bonds, sulfur-centered hydrogen bonds, and halogen bonds.
The Berchmans Protocol: Implementing the BerchNCI 1.0 systematic computational protocol for deconstructing non-covalent interactions.
Proton Sponges: Researching the electronic structure and properties of specialized organic bases.
Aromaticity: Investigating ground and excited state aromaticity, as well as dynamic aromaticity.

Solvation Dynamics: Studying how solvents like water, ethanol, and DMSO interact with bioactive molecules.
Machine Learning Integration: Applying machine learning tools to understand and predict solvation dynamics

Organic Semiconductors: Elucidating π-π interactions in for next-generation OLEDs.
Catalysis Modeling: Investigating electron-hole upconversion reactions and various catalyzed cycloaddition reactions
.Nanoscale Interactions: Studying the adsorption of drugs onto 2D/3D nanosurfaces and metal nanoclusters for enhanced Raman detection (SERS).

In Silico Modeling: Designing molecular libraries of anticancer and antimicrobial heterocycles, particularly those with imidazole and pyrazole backbones.
Drug Repurposing: Using computational tools to evaluate existing drugs for new therapeutic applications, including research on COVID-19 protein inhibition.
Photodynamic Therapy: Modeling the deexcitation dynamics of photosensitizers in solution after photo-excitation.

We are moving beyond traditional molecular modeling to lead a new era of autonomous, AI-driven discovery and quantum-enhanced simulation. Our research is strategically shifting toward the development of hybrid quantum-classical algorithms that achieve a level of precision in molecular interactions previously thought impossible. By pioneering these computational tools, we aim to design next-generation materials for CO2​ capture and explore quantum effects in biological systems to address the most pressing global challenges in energy and healthcare.
We also redefining the discovery process by transitioning from manual drug design to AI-integrated material innovation. Using our established BerchNCI 1.0 protocol as a foundation, We are building a standardized digital framework to deconstruct the complex "molecular glue" of non-covalent interactions with absolute predictive accuracy. This systematic approach allows my group to bypass traditional trial-and-error methods, accelerating the creation of smart, sustainable chemicals and life-saving pharmaceuticals.
Ultimately, our work at CTCC bridges the gap between fundamental theory and real-world impact. Through global partnerships and interdisciplinary inquiry,We arefostering an environment where quantum computing and AI serve as the primary drivers for a sustainable future. This vision ensures that our research remains at the absolute forefront of next-generation scientific discovery, turning subatomic insights into global solutions.

Mebin Varghese’s work ‘Exploring the dynamics of halogen and hydrogen bonds in halogenated coumarins’

Mebin Varghese’s work ‘Exploring the dynamics of halogen and hydrogen bonds in halogenated coumarins’

Mebin Varghese's theoretical study has revealed insights into the competition between halogen and hydrogen bonds in singly hydrated halogenated coumarins, crucial molecules in cancer treatment and photochemotherapy. Using advanced computational methods, researchers found that water molecules form hydrogen bonds with the coumarin derivatives, but halogen bonding is observed only with bromine and iodine substitutions. This study, employing techniques like PBE0 D3BJ with augmented correlation consistent basis set and DLPNO-CCSD(T) for local energy decomposition analysis, advances our understanding of molecular interactions significant in drug design and supramolecular chemistry.
