Interests: Observational cosmology, extragalactic and galactic astronomy, binary stars,

- First application of two-dimensional flat-fielding to a photoelectronic imaging device, 1970
- First evidence for merging of galaxies within clusters of galaxies, 1973
- First evidence for large-scale motions of clusters of galaxies, also known as cosmic flows, 1973, 1978
- Disproved the idea that first-ranked cluster galaxies have constant surface brightness, 1975
- The Cosmological Correspondence Principle, 1985
- Discovered a method of CCD operation known as Partial Inverted Operation, 1985
- Pioneered a method of accurate surface photometry of cluster galaxies whereby overlapping images of contaminating galaxies are iteratively modeled and subtracted, 1989
- Discovered a new systematic bias present in cluster galaxy data which affects relative distance estimates and evolutionary history; showed that the "fundamental plane" is really two intersecting planes; revised the "Faber-Jackson" relation, 1991
- Wrote and made available on the internet several astronomy software packages, including a widely used combined solution binary star program, 1992 - present
