Dr. J. Andrés López is an ichthyologist at the University of Alaska Fairbanks (UAF) where he holds a joint appointment with the College of Fisheries and Ocean Science as Associate Professor of Fisheries and the University of Alaska Museum as curator of the fish and marine invertebrate collections. Andrés has a master of science degree in Fisheries from the University of Washington and a doctoral degree in Ecology and Evolutionary Biology from Iowa State University. Andrés primary research interests center on the evolution of fish diversity with particular emphasis on the timing and pattern of diversification of freshwater fish groups. To understand fish evolution, Andrés and his collaborators most commonly use genetic data to reveal evidence of past and ongoing relationships between groups, species or populations of fishes. Over the past 10 years at the University of Alaska Museum, Andrés has overseen the growth of fish and marine invertebrate research collections through collaborative relationships with state and federal agencies, as well as the integration of an historically important research collection previously maintained at the Auke Bay Laboratories in Juneau. As a teacher and biologist, Andrés enjoys sharing stories of the rich and complex history of fish evolution and of the cultural and technological developments that shape our ability to understand the evolutionary process. Scientist in Residency Fellow mid April - mid May 2019
