Introduction
Current research projects include:
1) Investigation of the role of subsurface and surficial volatiles in the evolution of the Arabia Terra region of Mars.
2) Detailed investigations of central pit craters throughout the solar system and the role of subsurface volatiles in their formation.
3) Using crater statistical studies to constrain the contraction history of Mercury.
4) Investigation of the formation of unusual ejecta deposits on Mars.
5) Development of lunar crater database.

Differences in the shape and density of crater size-frequency
distribution curves have been interpreted as indicators of different
impactor populations. Within the inner solar system two production
populations are seen. The signature of the first is recorded in the
heavily cratered regions of the Moon, Mercury, and Mars and displays a
multi-sloped...
Internal and external processes have reworked the Earth's surface
throughout its history. In particular, the effect of meteorite impacts
on the early history of the earth is lost due to fluvial, aeolian,
volcanic and plate tectonic action. The cratering record on other inner
solar system bodies often provides the only clue to the relative
cratering...
This study has provided a more detailed chronology than currently exists in the literature and has created some changes to the currently accepted geological evolutionary sequence of Mars. The period of heavy bombardment, although dominated by impact processes, experienced many forms of volcanic activity and at least one episode of intense fracturin...
The Mariner 9 and Viking images of the Martian surface revealed much evidence of volcanic activity, both from early in the planet's history and more recently. The morphology of volcanic features range from plains to a variety of constructs, known as paterae, tholii (domes), and mons (shields) calculation of the density of superposed impact craters...
Existing Martian relative age chronologies rely entirely or predominantly on Mariner 9 images, extrapolated numbers of craters, and craters < 10 km in diameter. All of these factors produce uncertainties in the resulting cumulative size, frequency distribution curves from which the chronologies are derived. Data used in this study include craters g...
The cratering record in the inner Solar System shows two crater populations based on their size/frequency distributions. The heavily cratered surfaces of the Moon, Mercury and Mars all show a similar multisloped crater size distribution which represents the period of heavy bombardment. On the younger plains units of the Moon and Mars the crater siz...
The crater size/frequency distributions of large ( 8 km) craters on the Moon and terrestrial planets display two very different curves representing two crater populations. The heavily cratered regions of the Moon, Mercury, and Mars show the same highly structured curve which cannot be represented by a single slope distribution function. In contrast...
The Mars Crater Morphology Consortium ,was formed ,in 1997 to facilitate exchange of martian impact crater data among,researchers through standardizing nomenclature, integrating crater databases into one community-accessible GIS-based system, encouraging collaborations among researchers, and organization of Mars crater-related workshops and confere...
We used THEMIS night-IR imagery to characterize the preservation state of 5545 impact craters in selected regions of Mars. Our results support previous reports about the ages of these regions, episodes of degradation, and stability of subsurface volatile reservoirs.
We are conducting a comparison study of central pit craters on Mars and Ganymede, the first study of these features since the 1980's. We utilize THEMIS VIS and daytime IR data for Mars and Galileo and Voyager imagery for Ganymede. Our global study includes 1604 central pit craters on Mars (912 floor pits and 692 summit pits) and 471 central pit cra...
