Research topics:
Even their underlying old stellar populations are especially compact. Their Halpha SFRs are larger than SED-fit SFRs, indicating recent SF.
Some galaxies have enormous HI reservoirs but have almost totally failed to form any stellar populations.
Low mass central galaxies in small groups are more gas-rich and star-forming than those in isolation, perhaps fed by filaments of the cosmic web.
Cold gas mass predictions from dust
HRS sample, systematics
High-z HI detections, turbulence
Extremely low metallicity dwarf galaxies
Phosphorus production in AGB stars
Gas-rich ultra faint dwarf galaxies in the Local Group?
