Biography

My research interests focus on the use of theoretical & computational methods to study the properties of molecular solids and liquids and the self-assembly of both natural and synthetic macromolecules. In collaboration with brilliant students and postdocs, I have developed computational methodologies and carried out computer simulations to understand the phase behavior and properties of systems ranging from small molecules, such as water, to larger molecules such as surfactants and lipid bilayers, as well as natural and synthetic macromolecules. Other applications have been aimed at understanding the sensing and gating mechanisms Nature’s nano-scale machines, such as membrane-bound ion channels, as well as designing molecular therapeutics to combat both viral and bacterial infections.

PhD: 2007, SISSA – Scuola Internazionale Superiore di Studi Avanzati, Trieste, Italy

Affiliation: Department of Biology, Temple University

Phone: 215-204-4214

Email: [email protected]

Office: SERC 710

Bio and Research description:

Vincenzo Carnevale received B.Sc. and M.Sc. degrees in Physics from the University of Pisa and a PhD from SISSA – Scuola Internazionale Superiore di Studi Avanzati in Trieste, Italy. He currently holds the position of Associate Professor in the Department of Biology.

The Carnevale research group uses statistical physics and machine learning approaches to investigate sequence-structure-function relations in proteins. A central theme of the group’s research is how interactions give rise to collective phenomena and complex emergent behaviors. At the level of genes, the group is interested in epistasis – the complex entanglement phenomenon that causes amino acids to evolve in a concerted fashion – and how this shapes molecular evolution. At the cellular level, the group investigates how intermolecular interactions drive biomolecules toward self-organization and pattern formation. A long-term goal of the group is understanding the molecular underpinnings of electrical signaling in excitable cells. Toward these goals, the group applies and actively develops an extensive arsenal of theoretical and computational approaches including statistical (mean)field theories, Monte Carlo and molecular dynamics simulations, statistical inference of generative models, and deep learning.

Biography

I received my B.Sc. in Chemistry from Ramakrishna Mission Residential College, Narendrapur (Kolkata, India) in 2016. Subsequently, I joined the integrated Ph.D. program at the Indian Institute of Science, Bengaluru, India. After completing my M.Sc., I joined Prof. Biman Bagchi’s research group at the Solid State and Structural Chemistry Unit of the Indian Institute of Science (Bengaluru, India) in 2018. During my Ph.D., I formulated the multidimensional non-Markovian theory and explored it in studying kinetics in several systems, such as the cis-trans isomerization reaction of stilbene, insulin dimer dissociation in water, and gas-liquid nucleation. I also studied the diffusion-entropy scaling relation, the hydrodynamic Stokes law at molecular length scales, microdroplet chemistry, dielectric relaxation of dipolar confined fluids, etc. Currently, I am working with Prof. Michael L. Klein’s group at Temple University as a post-doctoral research associate. Looking ahead, I aspire to remain in academia to continue my research and teaching.
