Professor Ravi Jagadeeshan heads the Molecular Rheology group within the Department of Chemical Engineering at Monash University. His group is focussed on developing a theoretical and computational description of the flow behaviour of polymer solutions using a using a multiscale approach that combines molecular simulations at the mesoscopic scale with continuum simulations on a macroscopic scale. He is also interested in applying methods of soft matter physics to studying problems in biology. Professor Jagadeeshan attained his PhD in chemical engineering from the Indian Institute of Science in 1989. He undertook postdoctoral and research positions at the National Chemical Laboratory Pune (India), Cavendish Laboratory at the University of Cambridge (UK) and the Swiss Federal Institute of Technology Zurich (Switzerland). He was a Humboldt fellow at the Technical University of Kaiserslautern from 1999 to 2000, and in 2001 Professor Jagadeeshan joined Monash University.

Several systems such as granular materials, colloidal suspensions, polymeric liquids, and biological matter, are classified as complex fluids because their micro-structure crucially influences their material properties. These systems are inspiring several new technologies. A key challenge is to describe their flow behavior by understanding the connections between their microscopic structure and macroscopic properties. Ravi Jagadeeshan’s research is focused on developing a theoretical description of the complex flow of polymer solutions. Molecular models and a continuum level description are used in his group to advance the microscopic and the macroscopic description of complex fluid dynamics. The primary aim of the research is to gain fundamental insight into the computational modelling of complex fluid flow by using a multi-scale approach that combines insight at the microscopic scale with advanced numerical techniques on a macroscopic scale.
Professor Jagadeeshan’s research group is currently investigating:
Computing the dynamics of Chromatin folding.
Influence of shear flow, crowding and internal viscosity on semi-dilute polymer solutions.
Monitoring Drug Binding in Cells for Enhanced Drug Discovery.
Nanotechnology Enabled Electrochemical Energy Storage Materials from Indigenous Natural Graphite
Graphene, a 2D honeycomb arrangement of Carbon atoms of one atom thickness, is the center of attraction in nanoscience and nanotechnology. Graphene based macroscopic electrodes produced from exfoliation of graphite and their reconstitution have much higher surface area and ionic mobility in electrochemical energy storage devices. Utilising the state-of-the-art in nanomaterials processing, functionalization chemistry, characterization and computer simulations, the project aims to develop a technology package for reclaiming natural graphite fines mined in Southern Australia. Our partner organisation has a strong commitment indicated by a high cash to kind contribution, eagerness to collaborate and possibility of long-term alliances.
Hydrodynamic Fluctuations in Soft-Matter Simulations
Designing polymer additives to control breakup of jets and impacting drops
In agricultural spraying, pesticide is wasted as a fine mist, or because drops rebound off leaf surfaces, causing serious soil and water pollution. Small amounts of polymeric additives can add elasticity to sprayed liquids that greatly suppress these problems. We combine decades of expertise at Monash and MIT on the flow behaviour of dilute polymer solutions to investigate how chemistry, structure and concentration of such additives can be designed to control a spray-and-deposit process. This study will help to significantly reduce the serious environmental impact of pesticide wastage in agricultural spraying.

Biomedical Engineering Sensing and Imaging Facility
A major facility in biomedical engineering sensing and imaging is proposed. It will foster multidiscipline teams of medical and engineering researchers to develop innovative processes and technology for the prevention, diagnosis, and treatment of disease, for patient rehabilitation, and for improving health. The new facility will build on a number of existing research strengths and resources across the participating universities as well as the CSIRO and hospital-based research groups.

Understanding the Behavior of Single-Walled Carbon Nanotubes in Liquids
A significant hurdle to using Single Walled Carbon Nanotubes (SWNTs) for manufacturing materials capable of unprecedented performance has been the difficulty of arraying SWNTs into ordered macroscopic samples such as fibres. This research aims to obtain a detailed understanding of the liquid-state processing of pristine SWNTs, which is currently the most promising route for overcoming this challenge. It will lead to progress in porting properties from individual nanotubes to macroscopic fibres or sheets, and to important advances in realizing the goal of manufacturing the ultimate material.
The flow properties of proteins and other biopolymers
The living cell is an extraordinary organization with a vast variety of biomacromolecules carrying out myriads of functions with great specificity and accuracy. The key issue in cell biology is to unravel the structures of biopolymers and the deep connection that exists between structure and function. This interdisciplinary research program combines recent advances in experimental nd theoretical rheology, with advances in protein science, to investigate the response of biopolymers to deformation. This approach will lead to insights into the problem of protein folding, the interaction of biopolymers with surface, and the physical basis for the mechanical properties of biopolymers.

DNA Dynamics is shear and extensional flows: Simulation and single molecule experiments
The proposal seeks to establish a collaboration between Monash University and Standford University in order to combine several recent experimental and theoretical advances that have been made by the individual groups in single molecule experimental techniques, extensional rheometry, and molecular rheology to obtain new insights into the structure and dynamics of biopolymers. The central aim is to make a significant contribution towards bringing state-of-the-art techniques used for the characterization of polymeric systems to bear on the nature and origin of the elastic properties of biopolymers
