Bio

My research focuses on the application of artificial intelligence, particularly large language models and autonomous agents, to challenges in chemistry and chemistry education. My most recent project delves into using voxel-based representations within fine-tuned convolutional neural networks. This approach aims to accurately predict the free energy of solvation, a critical factor dependent on the 3D conformations of molecules. This work is instrumental in advancing drug development, particularly in predicting ligand-protein docking, a key process in pharmaceutical research.

My foundational training as a physical and materials chemist, with specialized expertise in photoactive materials, has provided me with a deep understanding of molecular behavior and interactions. In the last decade I concentrated on organic photovoltaics, where I explored the impact of small molecule packing and the role of aggregation in charge transport and photoinduced charge generation at donor-acceptor interfaces. Additionally, my work with photoactive self-healing polymers further reinforced my ability to analyze and manipulate complex materials.

This extensive background in chemistry and materials science now informs and enhances my application of AI-driven methodologies, allowing for more sophisticated models and predictions in molecular chemistry and materials research.

CHMP-342
3 Credits
This course provides fundamental concepts, and organizing principles of quantum chemistry, applied in all aspects of chemistry and related fields. A rigorous and detailed explanation of central, unifying concepts in quantum chemistry will be developed. Mathematical models will be described, which contain the underpinnings to concepts applied in analytical, inorganic, organic, and biochemistry courses, as well as more advanced topics in chemistry. The course will cover: Postulates and formulation of Schrödinger equations, Operators and matrix elements, Solutions for the particle-in-a-box, simple harmonic oscillators, the rigid rotor and angular momentum, the hydrogen atom; spin, the Pauli principle. Approximation methods will be described for the helium atom, the hydrogen molecule ion, the hydrogen molecule, Diatomic molecules. Linear combinations of atomic orbitals and computational chemistry will be introduced and quantum chemistry applications will be provided. In addition this course will cover standard thermodynamic functions expressed in partition functions and spectroscopy and light-matter interaction
