Observational Experience:

Space-based:

NASA Spitzer Space Telescope: 'Ultra-cool dwarfs viewed equator-on: surveying the best host stars for biosignature detection in transiting exoplanets' (P.I. Miles-Páez, 1074.7 h)

NASA TESS: 'Ultra-cool dwarfs viewed equator-on: surveying the best host stars for biosignature detection in transiting exoplanets' (Institutional PI: S. Metchev; USD 50k)

Ground-based:

I have been the PI of 18 accepted proposals (∼60 nights) and co-I in other 20 proposals (∼50 nights) using optical and near-infrared instrumentation on 1-10 m telescopes in various observatories, such as the Roque de Los Muchachos, Kitt Peak, Gemini North and South, and the Cerro Tololo Inter-American observatory. I have been observing at the telescope in ~100 nights, and I have more than 400 h of experience observing remotely using 1-m class telescopes.
