John's research focuses on fish diversity of South America. His taxonomic specialties are catfishes and electric fishes. He is a Co-Principal Investigator on the NSF funded All Catfsih Species Inventory. With previous funding from the National Science Foundation he has conducted ichthyological expeditions to explore the deep river channels of the Amazon River in Brazil and the Orinoco River in Venezuela. He also investigates fossil fishes from South America that show that many living groups of fishes are much older than once thought, that many fishes were more widespread in the past than today, and that local extinction has been a major factor in the modernization of the South American aquatic biota.

Mark has primary responsibility for the care and maintenance of our extensive collections. He also is involved in a taxonomic revision of the neotropical catfish family Doradidae (thorny catfishes) with descriptions of several new species, modern and fossil. Mark has field and collecting experience in freshwater ecosystems throughout the United States and on four continents including a total of 40 expeditions to Argentina, Bolivia, Brazil, Canada, Colombia, Finland, Guyana, Mongolia, Peru, Suriname, Thailand, Uruguay and Venezuela.
Kyle's first experiences at the museum came through the Academy's REU (Research Experience for Undergraduates) program, funded by the National Science Foundation, during the summer of 2002 in the Botany Department where he did some work with the collection as well as digital imaging and illustration. Kyle is currently assisting John Lundberg, through a NSF grant, in his research involving the discovery and description of the world's catfish species. His duties include digital imaging of preserved specimens and skeletal material, X-raying specimens, clearing and staining specimens, preparing skeletons, and preparing figures for publication. He is also working with Mark Sabaj, assisting with care and maintenance of the fish collection. Kyle's other interests include teaching, through the Scout Badge program here at the Academy, and working as a freelance scientific illustrator. He has done work for the Paleontology Dept. at the American Museum of Natural History, and is currently working with Academy Paleontologist Ted Daeschler, providing illustrations for his publications.

Dan Fromm and his wife Pat have collected fish in the new world tropics and have donated preserved specimens, primarily fish but also amphibians and aquatic insects, to the Academy and to the Smithsonian Tropical Research Institute. Their specimens have been used in a variety of studies including descriptions of new species. Dan, now retired, comes to the Academy to work up some of their specimens and to try to understand better what they’ve found.

His principal research interests focus on the diversity of tropical freshwater fishes, which has involved fieldwork to the Amazon and other major river systems ofBrazil, Bolivia, and Venezuela, and most recently at high elevations in the Andes of Ecuador, Peru, and Venezuela. He is one of the world’s leading authorities on the systematics and evolution of catfishes.
