Overview and Research Interests

I am a Research Scientist in the Computing Sciences Area at the Lawrence Berkeley National Laboratory. I have a combined background in computational science and domain sciences of physical waves and electronics. My current primary research interest is in high-fidelity computational algorithms for microelectronics applications. I work closely with material scientists, device designers, circuit architects and machine learning experts, to codesign workflow that benefits the development of future electronics.

Microelectronics and Quantum Chip Modeling

Emerging post-CMOS technologies often rely on trial-and-error development strategies due to the lack of adequate simulation tools. There is an ever-increasing need for higher-fidelity simulations via higher spatiotemporal resolution and/or improved coupling that can seamlessly incorporate new physics into algorithms for widely-used, standard models.
We address the need for enhanced modeling for more realistic devices by developing an algorithmically flexible capability that is performant on manycore/GPU-based supercomputers. The main product of this research is the Microelectronics package. Microelectronics package is able to effectively capture the multiphysics aspect of emerging microelectronics, with increased spatial resolutions. This allows for GPU simulations of various devices including multiferroic logic, ferroelectric capacitors and transistors, magnetic RF devices, high-frequency circuits, etc.

I received the Ph.D. degree in December of 2017 from Electrical and Computer Engineering (ECE) Department at University of California, Los Angeles (UCLA), and continued pursuing research in the same department as a postdoc until September of 2019. During my graduate study, my research has been centered on using new physical coupling in novel electronic devices, specifically the design and characterization of miniaturized multiferroic components in RF systems. I have proposed, modeled, and characterized strain-mediated multiferroic antennas , as well as contributed to building ferromagnetic resonance-enhanced electrically small antennas, Lamb wave resonators with parametric amplification, and magnetic field receivers based on resonant precession modulation.
