About

My research focus is in the area of applied cryptography. My recent work includes developing privacy-preserving cryptographic protocols for implementing anonymous electronic cash and identification. I helped to deploy the first two private, compliant stablecoins. I have also developed protocols that allow users to access databases without revealing which data they're accessing. Additionally, I have been working on new automation techniques to assist in the design and deployment of advanced cryptographic protocols.

  A new direct air capture (DAC) technology uses a moisture swing (MS) process with anion exchange membranes, potentially offering a more energy-efficient way to remove CO2 from the air. In this MS process, the membrane absorbs CO2 as it dries and releases it when water is added. Understanding the mechanical behavior of these membranes is essential for improving the design and efficiency of DAC systems and prolonging sorbent lifetime. This study tested one anion exchange membrane, Fumasep FAA-3, u…

• Design and demonstration of a direct air capture system with moisture-driven CO2 delivery into aqueous medium

  ArXiv.org · 2025-08-04

  preprintOpen access

  A moisture-driven air capture (DAC) system was designed and demonstrated. A laboratory-scale system delivering ~1 g CO2 per day was demonstrated in a laminar flow hood and a small pilot-scale system that could deliver ~100 g CO2 daily was operated outdoors in a 4.2 m2 (areal surface area) raceway pond. Elongated mesh tube packets were designed to contain AER beads with high surface area for contacting the air and were found to reduce drying and CO2 loading time ~4-fold over larger mesh bags. Whe…
