What I'm Working On

This page is my attempt to keep track of all the things I'm working on...

Blockchain Research

• Implementing RCanopus and further parallelizing the committer peer (with Christian Gorenflo, Ashwin Sekhari, Qingnan Duan, Linguan Wang, Lukasz Golab, Bernard Wong, and (at UMass) Stephen Lee and Prashant Shenoy)

• Designing a trusted smart meter to ensure that data that enters a blockchain can be relied upon. (with Dimcho Karakashev)

• Enhancing Fabric with quantum-safe cryptographic algorithms (with Bhargav Das, Amelia Holcombe, Geovandro Pereira, and Michele Mosca)

Energy systems

• Using computer science to improve forest landscape restoration (with Anil Madhavapeddy and David Coomes)

• Instrumenting campus buildings to measure electricity, chilled water, and steam heat consumption (with Ivy Liu, Yerbol Aussat and Costin Ograda-Bratu)

• Creating a website for homeowners and businesses to determine how many solar panels and how big a storage battery to buy to achieve a certain level of grid independence (with Brad Huang and Fiodar Kazhamiaka)

Misc.

• Designing an index to measure researcher influence and also identify potential research fraud (with Ankai Jie)
