About

Welcome to the Herrera Lab at the Department of Biological Sciences of Lehigh University.

Our research focuses on understanding the consequences of interactions between marine life and their environment, from geological to organismal time scales. We make use of high-throughput data-gathering methods and computation intensive approaches, in combination with oceanographic expeditions and laboratory experiments, to generate and test evolutionary and ecological hypothesis using a range of non-model biological systems.

Research Topics




  • Deep-Sea Ecology

    How widespread are species ranges at different depths?


    How homogeneous is genetic diversity within the range of a deep-sea species?


    What drives biodiversity, or lack thereof, in extreme deep-sea ecosystems?

  • Dynamic Biogeography of the Deep Ocean

    What are the controls on faunal biodiversification in the deep ocean?


    What are the mechanisms responsible for similarities in evolutionary relationships and distributions of different species?


    How often do biological invasions to new ecosystems happen in and from/into the deep?

  • Cold-water corals

    How do cold-water coral ecosystems respond to environmental changes?


    How can corals with lifespans of hundreds to thousands of years adapt to rapid changes?


    Why are there twice as many coral species living in the deep ocean, relative to shallow seas?

  • Genomics and Epigenomics

    How do organisms respond and/or adapt to environmental stress at the DNA and protein levels?


    Can epigenetic modifications be a mechanism of rapid adaptation to changing environments in species with long lifespans?


    How does the genetic background constrain epigenetic plasticity?

  • Bioinformatics

    How do we extract meaningful information from massive 'omics' datasets?


    How can different kinds of 'big data' be integrated to understand biological processes?

Fieldwork in the Deep Ocean

We have lead and participated in more than a dozen scientific expeditions to deep-sea hydrothermal vents, hydrocarbon seeps, active volcanoes, mid-ocean ridges, continental margins, seamounts, ocean trenches and abyssal plains. In doing so, we have explored regions of the Atlantic, Pacific, and Southern Oceans, the Gulf of Mexico, and the Celebes, Caribbean and Mediterranean Seas and conducted over 320 days of fieldwork and 110 submersible dives.
