  • Jul 2017 - Present

  ‣ Early Monreo results here: https://www.youtube.com/watch?v=XIrqyxU3k5Q ‣ Gathered a top-notch team to fill coding, analysis, and security/operational roles. ‣ Co-designed the Monero Archival Project's custom archival daemon. ‣ Discovered Big Bang attack on dynamic blocksize, subsequently mitigated in the Monero protocol. ‣ Quantified activity leaks through single-output transactions, resulting in Monero protocol modification. ‣ Uncovered transaction lock time anomalies, resulting in Monero protocol modification to prevent juvenile spending. ‣ Detected and documented selfish mining activity. ‣ Discovered anomalies such as Merlin blocks and non-latency-induced long alternative chains (e.g. routinely 30 blocks long). ‣ Quantified subtle (invisible) centralization due to IP bottlenecks. ‣ Discovered a new heuristic for tracking through Monero churn: identifying sets of transactions with non-standard decoy selection algorithms. ‣ Studied emergent behaviors arising from edge cases in game theory / financial incentivization. ‣ Began initiative to push for fixed fee options in future network upgrades. ‣ Learn more at https://noncesense-research-lab.github.io Show less

  • Jun 2018 - Jul 2018

  Designed and built OperatorAware, a quality assurance tool for 911 call center supervisor augmentation. OperatorAware listens to caller-dispatcher recordings and identifies emergencies that were not handled appropriately.



Uncaged Potential

• United States
• Research

• Researcher & Technical Editor

  • Jan 2018 - Sep 2018

  ‣ Founded the Monero Archival Project, which designed the first methods and tools that allowed detection of blockchain anomalies and study of network topology & latency ‣ Released the Seed Sieve algorithm, a modular text filter that allows any platform (e.g. social media, email, etc) to protect their users from accidentally revealing cryptocurrency seed mnemonic phrases. ‣ Copy edited Mastering Monero, the first official comprehensive guide for said cryptocurrency, to be published in fall 2018 as an electronic and hardcover resource. ‣ Invented machine learning classification tools for discerning evolutionary history and geographic origin from raw genetic data (consulting, led to patent exploration) ‣ Translated & copy edited technical articles (from Italian) ‣ Designed back-end signal processing (scaling and noising) of historical financial timeseries for use in an adrenalizing training simulator on cryptocurrency-fiat pairings ‣ Proposed improvements to Monero's fungibility by subjecting spend time distributions and decoy selection to improvement by generative adversarial network (GAN) learning Show less

• Research Assistant

  • Aug 2009 - May 2012

  ‣ Synthesized novel substituted benzofluorenone dyes, in order to analyze their ability to induce and report the formation of G-quadruplex structures. ‣ Experimentally determined element-specific error for x-ray fluorescence spectroscopy, and subsequently developed an improved standardization procedure for the device ‣ Studied zigzag instability in small clusters with fewer than 10 microspheres. Studied wave propagation in chains of dust particles more than one particle wide. ‣ Paired images of galaxies from NASA/IPAC Extragalactic Database with data for telescope positions. Matched observed photometric features to corresponding kinematic features. ‣ Calculated stellar kinematics such as rotational velocity and velocity dispersion for the central objects for four galaxies.
