Four Viterbi professors receive DURIP funding – USC Viterbi



Jay Ravichandran’s laboratory for complex materials and devices

The Defense University Research Instrumentation Program, which supports university research infrastructure, has chosen to fund four research projects at USC Viterbi. The projects cover a wide range of topics, including brain modeling, emerging materials, new fuels, and the automation of electromagnetic device design.

The Viterbi researchers were among the 144 university researchers selected by the Ministry of Defense. The researchers whose proposals were selected are Jean Marie Charles Bouteiller, Stephen Cronin, Jayakanth Ravichandran and Constantine Sideris. The projects are as follows.

Jean Marie Charles Bouteiller

Project: “Efficient scale transition methodologies for multiscale nervous system modeling”

Assistant Research Professor in Biomedical Engineering, Jean-Marie Charles Bouteiller studies the functioning of the nervous system in health and disease. As such, Bouteiller models in great detail the neuronal dynamics and synaptic transmission in the brain, thus making it possible to study the effects of drugs on different aspects of the functioning of the nervous system. Given the complexity involved, Bouteiller attempts to use mathematical models capable of predicting chemical interactions in the brain with a high level of realism and a reduced computational footprint. Bouteiller says: “The nervous system is inherently complex and multiscale – we have to find the right tools to model it: we have to get rid of the superfluous complexity and extract the essential accurately model the activity of the nervous system and its interactions with drugs in order to predict their effects on its health and functions. Bouteiller is also trying to understand the interaction between the electrical and chemical activity of the brain and compounds such as pesticides in order to understand their effects on neurodegeneration.

The award will allow his laboratory to have more computing power to accelerate and facilitate the development of more predictive models.

Stephane Cronin

Project: “Highly tunable ultrafast photon source for the interrogation of electrochemical and photocatalytic processes driven by hot electrons”

Funded by ARO, the laboratory of Stephen Cronin, professor of electrical engineering, physics and chemistry, studies the photoconversion of greenhouse gases into hydrocarbons. Cronin says of this project: “I am very excited to use this laser to explore new forms of chemistry driven by photoexcited electrons on metallic surfaces. Most of our previous work has been limited to steady state spectroscopy. This laser will allow us to extend our study into the time domain and explore the dynamics and time scales on which these chemical reactions occur.

Jayakanth Ravichandran

Project: “Characterization of the growth and in situ of thin layers of perovskite chalcogenides at incompatible vapor pressure”

For Jayakanth Ravichandran, Assistant Professor of Chemical Engineering and Materials Science and Electrical and Computer Engineering and Philip and Cayley MacDonald Early Career Chair, the award, funded by AFOSR, will help support the development of a new class of materials. which will allow secure communication and energy efficient electronics. In addition, it will help in the development of new materials that can improve infrared detection and imaging. This Ravichandran Laboratory for Complex Materials and Devices project is linked to work funded by a multi-university research initiative earlier this year to develop materials that support secure communication, sensing, memory and storage in the devices.

Constantin Sidéris

Project: “Advanced numerical methods at the petascal scale for the resolution and inverse design of massive computational physics problems”

Funded by AFOSR, this award will enable Sideris’ Analog / RF Integrated Circuits, Microsystems and Electromagnetism (ACME) laboratory at Sideris to create a high performance computing cluster based on GPU (Graphics Processing Unit) to advance research in computational electromagnetism.

Sideris, assistant professor in electrical and computer engineering and holder of a Viterbi Early Career chair, says: “The cluster will allow us to develop and execute highly parallelized algorithms to simulate and automate the design of very large and complex electromagnetic structures, such as nanophotonics devices and radio frequency antenna arrays. Such devices are ubiquitous in today’s technology and impact many applications such as wireless telecommunications and detection systems. Unfortunately, electromagnetic devices tend to be notoriously difficult to design manually, even for experienced engineers. Improved designs with higher yields, lower costs, and smaller sizes have become of critical importance in meeting society’s increasing performance demands for technology. This project aims to develop algorithms capable of synthesizing new electromagnetic devices from only the desired performance specifications as inputs, which can exceed the performance of human-designed devices and save time on tasks requiring design. manual.
