Evaluating Characteristics of CUDA Communication Primitives on High-Bandwidth Interconnect

Published in International Conference on Performance Engineering, 2019

CommScope is a set of microbenchmarks designed to help system and application developers analyze and optimize memory transfer behavior across various data placement and exchange scenarios in heterogeneous systems. It evaluates CUDA data transfer primitives on architectures like POWER and x86 with interconnects such as PCIe and NVLink, providing insights into system design and application optimization.

Collective Identity in Collective Action: Evidence from the 2020 BLM Protests

Published in Frontiers in Political Science, 2023

This study investigates the role of collective identity versus individual interest in driving protest participation, using data from Twitter users involved in the 2020 Black Lives Matter protests. The findings suggest that individual interest, rather than collective identity, is a stronger predictor of protest participation, challenging prior research that conflated these factors and overestimated the role of collective identity.

Enabling Computational Democratization: A Proof-of-Stake Bounty System for User-Proposed Problems and Solutions.

Published in MIT Undergraduate Research Technology Conference, 2023

A novel framework replaces energy-intensive Proof-of-Work (PoW) mining with a modified Proof-of-Stake (PoS) consensus mechanism that rewards miners for solving user-proposed computational problems. This approach incentivizes PoW miners to transition by allowing them to leverage their existing hardware investments.
