Christopher H. Martin

edit

Christopher H. Martin is an American evolutionary biologist serving as an Associate Professor in the Department of Integrative Biology at the University of California, Berkeley. He leads the Martin Fish Speciation Lab, focusing on the evolution and ecology of adaptive radiation in fishes.[1]

Education and Early Career

edit

Martin earned his B.S. in Biology from Duke University in 2005. He then spent a year living in Malawi on a Fulbright scholarship studying cichlid diversity. He completed his Ph.D. in Population Biology at the University of California, Davis in 2013 with advisor Peter Wainwright. He received a Miller Postdoctoral Fellowship[2] at UC Berkeley and worked with postdoctoral mentors Craig Miller and Erica Bree Rosenblum for two years. He then began his first academic position in the Biology Department at the University of North Carolina at Chapel Hill in 2015.

Academic Position

edit

Joining the UC Berkeley faculty in 2019 as part of the Department of Integrative Biology and Curator of Ichthyology in the Museum of Vertebrate Zoology[3].

Research Focus

edit

Martin's lab investigates the mechanisms behind rapid speciation and the origins of biodiversity, particularly in tropical fish systems. The lab uses field experiments, natural history observations, population genomics, behavioral ecology, functional morphology, quantitative and functional genetics, and phylogenetic methods to understand evolution within rapid radiations of three or more species.The lab's goal is to map the complex interactions among genotype, phenotype, performance, fitness, and environment to understand adaptive diversification.

Notably, the Martin lab published the genome assembly for the Devils Hole pupfish, discovered three novel craniofacial development genes, and popularized pupfishes as an evolutionary model system.

Key Model Systems

edit

The lab’s research spans three prominent case studies:

  1. Caribbean pupfishes, notable for microendemic adaptive radiations of trophic specialists in the Bahamas and Yucatán.
  2. Cameroon crater lake cichlids, classic examples of sympatric speciation.
  3. Death Valley pupfishes, critically endangered desert fishes with extremely limited ranges.
