AAVSO's Stellar Spectroscopy Database

AVSpec is the first spectral database of the American Association of Variable Star Observers. Accessible to any astronomer with the capability to perform spectroscopy, AVSpec is the world-leading database for amateur spectroscopy of variable stars and novae.

​I was the Development Director of AVSpec from 2016 - 2018, developing the concept, backend, and frontend of the the database. I was supported in this role by the 2016 & 2017 Margaret Mayall Fellowships.

The site is now live: www.aavso.org/apps/specdb

My research interests lie almost exclusively within the realm of extragalactic astrophysics and cosmology. I use state-of-the-art optical and infrared observatories and surveys to study the lives of galaxies, and how their properties change over cosmic time. This includes detailed case studies of individual galaxies, as well as statistical analyses of large survey catalogs.
