About

Dr. Juner Zhu joined the faculty of Northeastern University as an Assistant Professor of MIE in August 2022. Before that, he was a Research Scientist at MIT in Mechanical and Chemical Engineering. He received his Ph.D. from MIT in 2019. Juner co-developed the 2020-2022 phase of the MIT Industrial Battery Consortium and acted as the Executive Director working with eight world-leading companies in EV, battery, and electronics. He got his B.S. and M.S. degrees from Tsinghua University, where he graduated with top honor (the Top Grade Fellowship) for Tsinghua graduate students 2014-2015. Juner is leading the Electro-Chemo-Mechanics Lab on the Innovation Campus at Burlington. His research group tackles the fundamental challenges of integrating data-driven methods with physics-based theories for complex engineered systems with a particular interest in Li-ion batteries, solid-state batteries, and Li-metal anode.

Research Overview

Electro-chemo-mechanics, energy storage systems, scientific machine learning, battery sustainability and safety

Five out of the fourteen Grand Challenges for engineering in the 21st century identified by the National Academy of Engineering lie in the difficulty of deciphering complex natural or engineered systems. An extremely large example is the earth’s climate, the understanding for which the 2021 Nobel Prize in Physics was awarded. A smaller example is energy storage systems (ESSs) such as lithium-ion batteries (LIBs), the main technology that the 2019 Nobel Prize in Chemistry was awarded. The complexity of such systems comes from two major aspects: i) multiple length- and time-scales and ii) Coupled physical effects, such as mechanics, chemical reactions, and mass transport in LIBs.

The fundamental challenge of systematic engineering lies in the tradeoff between the abundance of data and the adequacy of physical laws. At the microscale, physics can usually be elucidated, but data are expensive and limited; at the macroscale, physical laws are often hidden in the big data that are hard to decipher. Physics-based or first-principle-based theories are robust but suffer from the “curse of dimensionality” as the number of variables and degrees of freedom increases. Recently, many data-driven approaches particularly machine learning have shown advantages in dealing with high-dimensional problems, but they are usually agnostic and prone to unphysical failure.

The research interest of the Juner Zhu Group lies in seeking the intelligent integration of physics-based theories and data-driven approaches using our intersectional expertise in applied mechanics, electrochemistry, system engineering, and data science.
