Computer Science PhD Student


I am a second year PhD student in the System Level Design group in the Computer Science department at Columbia University, focusing on heterogeneous system-on-chip architectures. My research interests include novel architectures, runtime management, and agile design techniques for many-accelerator systems-on-chip.

In 2019, I completed a Bachelors of Science in Electrical Engineering from Harvard University. At Harvard I studied computer hardware across the full-stack, learning architecture, circuits, VLSI, systems, algorithms, and applications, and, in particular, focused on the design of architectures for machine learning applications.

A product of many years of research from the SLD group at Columbia, ESP is an open-source platform for heterogeneous SoC design and prototype on FPGA. It provides a flexible tile-based architecture built on a multi-plane network-on-chip.

In addition to the architecture, ESP provides users with templates and scripts to create new accelerators from SystemC, Chisel, and C. The ESP design methodology eases the integration process by offering platform services, such as DMA, distributed interrupt, and run-time coherence selection, that hide the complexity of hardware and software integration from the accelerator designer.


A collaboration between IBM, Columbia, Harvard, and UIUC, the EPOCHS project is funded within the DARPA Domain-Specific System-on-Chip (DSSOC) program. EPOCHS is part of an effort to enable the rapid development of multi-application systems through a single programmable device.
