Malcolm Maden (pictured left in photo with Paul Martin). Professor of Biology, Department of Biology, University of Florida. Malcolm served as my postdoctoral adviser, mentor, tennis partner, and is a renowned regeneration and developmental biologist. Malcolm and I collaborate intellectually on multiple aspects of regeneration.  Paul Martin was instrumental in helping inform my early work with spiny mice and conducts wound healing and regeneration research across a broad array of animals.

Spiny mouse consortium. With more biologists adopting spiny mice to study regeneration, reproduction and behavior, a spiny mouse community has begun taking shape. With a genome sequencing project complete, (see resources page) we continue to expand our molecular toolbox and look forward to a lifetime of productive collaborations. An ever-expanding list includes over 50 researchers worldwide.

Stephen G. Kiama Vice Chancellor, University of Nairobi and Professor of Veterinary Anatomy and Physiology, Department of Veterinary Anatomy and Physiology, University of Nairobi. Dr. Kiama and I are collaborating (with Vanessa Ezenwa) on research that tests how biases in immunity impacts regeneration in African spiny mice. As a visiting professor in the Department of Anatomy and Physiology I advise graduate students with Dr. Kiama working on wound healing and regeneration in mammals. We are also working together to develop opportunities that can bridge the gap between biomedical research in East Africa and the United States.

Sarah Calve (pictured at left) Associate Professor of Mechanical Engineering, UC Boulder. Dr. Calve and I share an interest in how the extracellular matrix can control cell behavior in the context of development, repair and regeneration. Sarah has been developing new methods to visualize the matrix in whole embryos and in  different injury paradigms.  We are currently exploring how the extracellular matrix may control the regenerative response in African spiny mice. 

Vanessa Ezenwa Professor, Department of Ecology and Evolutionary Biology, Yale University. Dr. Ezenwa and I collaborate (with Dr. Kiama) to examine how inflammation and immunity affect regenerative ability in wild populations of African spiny mice. 

Adrian C. Stier (right) is an ecologist & marine biologist and Bret Pasch (center) is a mammalogist & vertebrate biologist. We've mastered the art of work and play together and collaborated on several projects since graduate school. Recently Adrian and I began working together to look at tissue repair and regeneration in stony corals.

Carla Rothlin and Sourav Ghosh are biologists of the highest caliber and co-direct a laboratory at Yale. Carla is the Dorys McConnell Duberg Professor of Immunobiology and Professor of Pharmacology and Co-Leader of Cancer Immunology at the Yale Cancer Center and Sourav is an Associate Professor of Neurology and Pharmacology at Yale. We share an interest in trying to better understand how the inflammatory response is regulated during injury to positively affect tissue repair and regeneration. Our collaborative work addresses this problem by studying macrophage behavior.
