Postdoctoral Scholars

Sammy Andrzejaczek

I joined the Block lab in 2019 and am broadly interested in using modern tagging technologies to better understand the movement and behavioural ecology of sharks and other large pelagic predators. I completed my PhD at the University of Western Australia where my research focused on investigating the patterns and drivers of vertical movements of sharks and other large epipelagic predatory fishes. At Hopkins Marine Station, I aim to continue to investigate the vertical movement patterns of these animals, as well as evaluate how best to incorporate these findings into conservation and (...)

Simon Dedman

My work focuses on the use of machine learning approaches to understand the drivers of the movements of sharks and tuna, then predictively map these species to inform conservation management. I have developed software that automates and facilitates the use of Boosted Regression Tree techniques to ecological data, advancing the use of this approach among the shark community. Areas of study have been sharks off the coast of southern England, rays in the Irish Sea, lemon sharks in the Bahamas, anchovy off California, tuna in the North Atlantic, and sawfish off Florida.

Murray Duncan

I am a marine scientist trying to understand how environmental conditions drive ecological patterns of fish and fisheries through a physiological lens. The goal is to generate knowledge that can be incorporated into fisheries management frameworks to enhance resource sustainability. I earned my PhD at the Department of Ichthyology and Fisheries Science, Rhodes University under the supervision prof. Warren Potts in the SAFER lab, Dr Nikki James and Dr Amanda Bates in the Physiological Diversity Lab at Southampton University. I subsequently did a postdoc with the South African Institute for (...)

Laurent Formery

I graduated from Sorbonne University (France) in Molecular and Cellular Biology, and I started my PhD at the Villefranche-sur-Mer marine station, where my research focused on the develoment and evolution of the nervous system in sea urchins, and on the roles of intercellular signaling pathways in this process. As part of my PhD, I spent one year at the Shimoda Marine Research Center (Japan). I am now trying to understand how morphological diversity emerged from gene regulatory networks, using echinoderms and other cool animals like accorn worms. I am broadly fascinated by developmental (...)

Danielle Elaine Haulsee

Danielle Haulsee's interests include combining innovative technology and oceanographic remote sensing techniques with the biogeography and movement of marine species. She received her B.S. in Environmental Science from Gettysburg College in 2010 and her Ph.D. from the University of Delaware in 2017. At the University of Delaware she worked as a Ph.D. student and post-doctoral researcher with Dr. Matthew Oliver in the ORB Lab, focusing her research on threatened Sand Tiger sharks and endangered Atlantic Sturgeon. She used statistical models to quantify the habitat preferences, migratory (...)

Shaili Johri

I am a geneticist who works in the field of marine science and conservation. My work is aimed at reducing knowledge gaps in conservation science through scientific research, community partnerships and knowledge exchange across disciplines. Genomics research by our group aims to inform conservation policy and assist in reducing illegal wildlife trade.

Mikaela Provost

My research uses theoretical and empirical approaches to address applied problems in fisheries management and marine conservation. My projects span multiple species and places. Currently, I study abalone in Baja California, Mexico and the effects of climate-change refugia on abalone population dynamics with Dr. Giulio De Leo and Dr. Fiorenza Micheli at Hopkins Marine Station.

Paolo Segre

Maneuverability is critical to survival and plays an important role in prey capture, predator avoidance, and territorial disputes. I am interested in the fluid dynamics, kinematics, and ecological correlates of maneuvering performance across a range of animals. My PhD research focused on quantifying and comparing the acrobatic maneuvers of tropical hummingbirds in Central and South America. At Hopkins Marine Station I am applying similar engineering principles to the study of maneuvering performance in free ranging rorqual whales.
