Research Field Research Interests

1. Characterization of L subdwarfs: discovery, classification, atmospheric and population properties (Primeval - IPrimeval - IVZhang+18cPrimeval - V).

2. Search for the most metal-poor very low-mass stars, transitional brown dwarfs (T-BD; Primeval - IIPress releasePrimeval - III) and degenerate brown dwarfs (D-BD; Primeval - VI) in the Milky Way.

3. Revealing the observational and physical properties of very low-mass stars and brown dwarfs with benchmarks in binary systems

(Burgasser+25pressBenchmark - IPress releasePrimeval - VIIIPress releasePrimeval - VIIZhang+13Zhang+10Press releasePavlenko+15).

4. Discovery and characterization of ultracool dwarfs in large area surveys (Zhang+09Burningham+10Day-Jones+13).
