Signal Synchronization Strategies and Time Domain SETI with Gaia DR3
The Astronomical Journal, 2023 Spatiotemporal techniques for signal coordination with actively transmitting extraterrestrial civilizations, without the need for prior communication, can constrain technosignature searches to a significantly smaller coordinate space.

Search for Extraterrestrial Intelligence with the ngVLA
The Astronomical Journal, 2022 Abstract The next generation Very Large Array (ngVLA) will be the premiere centimeter-wave radio array in the Northern Hemisphere by the mid 2030s and thus has the potential to be one of the most effective instruments for the search for extraterrestrial intelligence (SETI).

The Local Galactic Transient Survey Applied to an Optical Search for Directed Intelligence
The Astrophysical JournalWe discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrestrial Intelligence sources in the closest galaxies. Our analysis follows P.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
Mass Spectrometry Reviews, EarlyView.ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is
