Pespeni Lab Photo – Fall 2020

Principal Investigator

Melissa H. Pespeni

Melissa is an evolutionary biologist interested in identifying the molecular underpinnings of complex adaptive phenotypes and understanding how ecological and evolutionary processes interact to shape a species’ or population’s capacity to adapt to current and future biotic and abiotic challenges. Her research involves genomic and physiological analyses in both natural and experimental populations. Read more about her personal story here.


Postdoctoral  Fellows

Inquire with Melissa. As of Fall 2021, she has funding for two postdocs.

Graduate Students

Lauren Ashlock

Lauren is a PhD candidate interested in understanding the potential resilience of marine organisms to global climate change. She uses multi-generational selection experiments in marine copepods to investigate the adaptive capacity for response to multiple and sequential biotic and abiotic stressors. As a fellow in the QuEST graduate training program, she has done an applied internship at the Farallon Institute.


Alison Hall

Alison is a PhD candidate interested in understanding the evolutionary mechanisms that underlie adaptation to climate change in marine ecosystems. She is excited to use genetic and genomic tools to conserve biodiversity and understand broader ecological implications of adaptation. Outside the lab, Alison enjoys playing in the beautiful East coast outdoors.

Csenge Petak

Csenge is a PhD candidate interested in molecular evolutionary biology and computational modeling. She is exploring the structure and function of sea urchin gene regulatory networks to infer their evolution and how they might facilitate evolvability. As a trainee in the QuEST graduate training program, she is planning to participate in interdisciplinary research regarding the general behavior of systems and the emergence of modularity.

Andrew McCracken

Andrew is a PhD student interested in understanding the role of the microbiome in animal health, particularly in the context of globally changing biotic and abiotic conditions. He is excited to integrate genomic, transcriptomic and molecular tools to explore the effects of specific conditions on disease phenotypes and identify the mechanisms underlying resistance, resilience, and vulnerability in wildlife diseases.


Undergraduate Students

Chelsea Darwin

Chelsea is a Biological Sciences major interested in marine biology and global change research. Her thesis explores the adaptability of the marine copepods to different environmental stressors such as changes in temperature and salinity.

Anya Steinhart

Anya is a Biology major interested in genetics and global change research.  She has designed her thesis to explore the genetic and physiological response mechanisms of the tropical sea urchin Lytechinus variegatus to extreme low salinity events, mimicking tropical storms.

And YOU?!

If you are a highly motivated and dedicated undergraduate interested in our research, please read, fill out, and send this application to Dr. Pespeni with an introduction to your motivations!  The typical flow is to first become familiar with the organisms and types of research questions addressed and tools used in the lab.  To do this, you would assist with current research projects and attend weekly lab meetings.  If you are particularly attentive to detail and compassionate, you can shadow current lab assistants to learn the ropes to become an animal care technician.  After on average a year in the lab doing the above activities, you may feel confident in designing and carrying out your own research project with Dr. Pespeni’s guidance.

Former members

Reid Brennan

Reid was a postdoc in the lab and is now junior faculty at GEOMAR in Kiel, Germany! Reid is an evolutionary biologist interested in how organisms respond and adapt to abiotic stressors. He is particularly focused on the mechanisms that enable populations to adapt to and persist in novel environments and utilizes physiological, transcriptomic, and genomic approaches.

Emily Shore

Emily earned her Masters in the lab as a student interested in human impacts on the environment.  Her thesis explored the impacts of microplastics on the fitness and behavior of copepods.

April Garrett

April earned her Masters in the lab as a student interested in understanding how multiple environmental stressors (particularly ocean warming, acidification, and disease outbreak) impact the physiology and resiliency of marine invertebrates and the adaptive capabilities of their subsequent populations.
