Presenter: Santanu Chaudhuri, Argonne National Laboratory
Abstract: Understanding the dynamic nature of materials and evolution of material interfaces produced during manufacturing are crucial for microelectronics, sensing, and IoT applications. Controlling different methods for surface activation, growth, carrier density, and creation/annihilation of defects will be crucial for producing high-performance devices from promising 2D materials. Predictions from first-principles methods alone are difficult to connect the different length scales involved. Novel machine learning methods can help in this process when combined with first-principles calculations for the formulation of 2D-materials into inks. Multiphysics simulations of the manufacturing processes, and the ability to use in situ experimental measurements for the steering of manufacturing processes can significantly improve the capacity to produce custom sensors and devices. Ongoing work on machine learning for acceleration of materials synthesis, processing and 3D printing guided by atomistic and mesoscale simulations will be discussed. In particular, atmospheric pressure plasma for surface modification and growth, inkjet/aerosol-jet printing of electronics, and better control of microstructure will be discussed as examples of promising multiscale approach.
Bio: Santanu Chaudhuri is the director of manufacturing science and engineering at Argonne National Laboratory. He is also a professor of civil, materials, and environmental engineering at UIC, with a courtesy appointment in the chemical engineering department. Chaudhuri moved to Argonne and UIC in 2017, after serving as associate director in the Applied Research Institute at the University of Illinois Urbana-Champaign. Chaudhuri’s group, Accelerated Materials Research Laboratory (AMRL website: http://amrl.uic.edu), is working on advancing first-principles theory and molecular dynamics methods for developing multiscale science approach for structure-property-processing relations for the design of materials and manufacturing processes. Chaudhuri’s team develops atomistic and mesoscale simulation tools for using high-performance computing resources. Use of materials databases, high-throughput DFT, and computational workflow to inform machine learning models are currently the focus of multiple ongoing projects in the group.
Chaudhuri earned his PhD in materials chemistry and chemical physics from SUNY Stony Brook New York in 2003. During his graduate study, he received a NATO scholarship to work at Oxford University, developing first-principles guided molecular simulations of ionic conductors, catalysts and battery materials. From 2003-2006, Chaudhuri worked as postdoctoral research associate in Brookhaven National Laboratory’s Center for Functional Nanomaterials on developing DFT guided search and design of hydrogen storage materials for automobile applications.
