High Contrast Probe Cleavage Detection (CRISPR-diagnostics readout with Silicon Photonic biosensors)
Post-deadline talk at OSA Frontiers in Optics and Laser Science conference… needs work, next one on this topic I will add a clearer discussion of how CRISPR diagnostics work.
Towards Optical Proof of Work; MIT DCI Cryptoeconomic Systems Conference 2020
This one went much better than the Tel Aviv talk in 2019. 20 minutes was a much constraint.
The associated publication: Towards Optical Proof of Work Dubrovsky et al.
Optical Proof of Work; Scaling Bitcoin 2019
A project I’ve been working on for a while (and finally making some progress!)

First experimental results showing HCPCD works
High Contrast Cleavage Detection
Theory paper on a new sensing method we invented at SiPhox to read out CRISPR and Toehold Switch RNA/DNA diagnostics with silicon photonic sensors.
Towards Optical Proof of Work
The full conference paper with details on Heavy Hash and various extras.
Optical Proof of Work Whitepaper, Nov 2019
We finally published an overview of oPoW (cryptography excluded) on arXiv. Academic paper with the cryptography recently submitted for peer reviewed publications.

Simply Grid @ Techcrunch Disrupt 2014
I spent a good part of my early 20s waging a crusade against urban emissions.
Simply Grid, initial deployment at Union Square 2013
This was supposed to be the first of thousands of installations via multiple city partnerships. This is how I learned that cities can remain irrational longer than you can remain solvent :).
