Asteroids have great interest: not only do they preserve information about the earliest times in the pre-Solar nebula, and as a result contain unique minerals, they are also hazards to the Earth (see Chelyabinks) and are the easiest objects to reach with spacecraft. As targets for human exploration, scientific discovery, retrieval to Earth-Moon space and sources of abundant resources both for space and on Earth, asteroids are worth paying attention to. I investigate all aspects of near-Earth asteroids related to hazards, expeditions and especially resources, i.e. asteroid mining. Read more about Martin Elvis: Asteroids
For a long time we have known that our view of the centers of quasars is often blocked by optically thick dusty material - the ‚Äúobscuring torus‚Äù. But to block a large solid angle requires a large height/radius ratio which is hard to achieve with cold matter. Andy Lawrence and I proposed that a thin torus that is twisted through large angles is a natural solution. I am investigating the spectral energy distributions (SEDs) of quasars in SDSS adding near-IR UKIDSS and mid-IR WISE data to see if the predictions of our model hold up.

Detection and characterization of exoplanetary atmospheres, with emphasis on developing new observational techniques to study the atmospheres of the Earth-like planets to be discovered by the NASA TESS mission.
