Visiting scientist program

  • The Murawala lab firmly believes that today’s science is highly interdisciplinary and requires collaborative efforts among like-minded people. 
  • With an active visiting scientist program at MDIBLevery year we welcome many researchers from across the world to spend a few weeks/months with us in the pristine environment of Mount Desert Island. These researchers enrich our knowledge and also get opportunities to learn science that is ongoing in our lab. 
  • If you would like to visit our lab to foster collaborations, please write to Prayag

Elena Pokidysheva, Visiting Scientist 2023

– Research Assistant Professor, Vanderbilt University, USA

Dr. Pokidysheva is a Research Assistant Professor in the Division of Nephrology, Department of Medicine at Vanderbilt University Medical Center in Nashville, TN. Her current studies focus on uncovering mechanisms of kidney failure caused by Alport syndrome. She is a visiting scientist at the Murawala Lab looking to extend her research through analysis of axolotls as a new animal model of Alport syndrome. The majority of Alport patients are missing collagen IV α345 scaffold in their glomerular basement membrane (GBM). Axolotls are naturally occurring double knockouts of col4a3 and col4a4 genes which makes them a unique model to study the disease.

Erik Figura, Visiting Scientist 2023

– Cand. Medical Doctor, Hannover Medical School, Germany

Erik Figura is a medical student at the Hannover Medical School (MHH), Germany. Currently, he is part of the Hinze Lab at Clinic for Kidney and Hypertension Diseases (MHH). Mr. Figura is interested in kidney research and regeneration potential. He is a visiting scientist in the Murawala lab at MDIBL as part of a joint project between the Hinze Lab and the Murawala lab. In this collaborative project Mr. Figura will study the cellular heterogeneity of the axolotl kidney using single cell transcriptomics, modern molecular biology and histology methods in both, the neotenic and the metamorphic state to build the first comprehensive genetic cell type atlas for the axolotl kidney.

Karen Crawford, Visiting Scientist 2023

– Professor, St. Mary’s College of Maryland, Maryland

Prof. Crawford is a developmental biologist. Her laboratory studies the cellular and molecular mechanisms of pattern formation during development and regeneration in animals. During the school year, her students study limb regeneration in the Mexican salamander (Ambystoma mexicanum), head and tail regeneration in a freshwater worm (Lumbriculus variegatus), and signal transduction cascades associated with pattern formation during development in squid embryos (Doryteuthis pealei, previously Loligo pealei).  Most summers, her research program moves to the Marine Biological Laboratory in Woods Hole, MA, where she has developed in vitro fertilization, culture and most recently, reliable microinjection methods for cephalopods. With this advancement her work has expanded through important collaborations to include CRISPR-Cas9 genome editing in squid. Her current collaborations include studying: heart, statocyst, and nervous system development, in addition to exploring fundamental questions of early patterning and development through CRISPR-Cas9 gene knockout and lineage analysis. Her studies in regeneration have also taken her to Dresden, Germany, and the MDIBL, Bar Harbor, ME, where she created and codirected the inaugural Regenerative Biology course. Over the years, she has served on both NIH and NSF grant review panels, and as a reviewer for a wide range of journals. She currently serve on the editorial board for Developmental Biology. She has also held a variety of leadership positions for the Society for Developmental Biology, Society for Comparative and Integrative Biology, and the Marine Biological Laboratory, Woods Hole, MA, where she currently chairs the Whitman Scientist Steering Committee.

Moshe Khurgel, Visiting Scientist 2023

– Associate Professor, Bridgewater College, Virginia

Prof. Khurgel’s fascination with morphogenesis began as an undergraduate student studying claw regeneration in lobsters with Dr. C.K. Govind at the University of Toronto and the summer lab at MBL. After exploring the role of astrogliosis in epileptogenesis and spinal cord regeneration, and stem cell transplantation for tissue repair in mammals during his Ph.D. and pos-doctoral studies, Dr. Khurgel set up his own lab with a quest is to understand how changes in metabolism influence development and limb regeneration in axolotls. He is collaborating with Murawala lab on the use of transgenic technologies.

Catherine McCusker, Visiting Scientist 2022-23

– Assistant Professor, University of Massachusetts, Boston

Prof. McCusker studied craniofacial development using Xenopus during her Ph.D.  in the lab of Dr. Alfandari at the University of Massachusetts, Amherst. She did her postdoc with Prof. Susan Bryant and Prof. David Gardiner at the University of California, Irvine studying axolotl limb regeneration. Since 2015, she is running her own lab at the University of Massachusetts, Boston in the department of Biology. Her core interests are limb development and limb regeneration. The Murawala lab collaborates with the McCusker lab on the role of nerves during axolotl limb regeneration.

Fabian Voigt, Visiting Scientist 2022-23

– Postdoctoral Researcher, Harvard University, Boston

Dr. Voigt is a developer of the mesoSPIM microscope during his Ph.D. in the lab of Dr. Fritjof Helmchen, University of Zürich, Zürich. Currently, he is doing his postdoctoral research in the lab of Dr. Florian Engert, Harvard University, Boston. So far, he has overseen the development of 12 mesoSPIM microscopes in various parts of the world. Dr. Voigt was instrumental in our effort to build a mesoSPIM microscope at the MDI Biological Laboratory which was built in 2022. He continues to collaborate with the Murawala Lab to improve the functionality of mesoSPIM microscopy further.

Hillary Maddin, Visiting Scientist 2022

– Associate Professor, Carleton University & Canadian Museum of Nature, Ottawa, Canada

Prof. Maddin did her Ph.D. in evolutionary biology at the University of Calgary and her postdoc with Prof. James Hanken at the Harvard University. Since 2015, she is running her own lab at the Carleton University. Her core interests are morphological and structural evolution of body plan with a special focus on amphibians. The Murawala lab collaborates with the Maddin lab on fin to limb evolution and understanding the principles of limb field induction.

Johannes Roeles, Visiting scientist 2021

– Resident Physician, Hannover Medical School, Hannover, Germany

Dr. Roeles did his medical doctorate (Dr. med.) from Hannover Medical School, Germany. Currently, he is serving as a resident physician at the Clinic for Kidney and Hypertension Diseases, Hannover Medical school. Dr. Roeles is passionate about vascular architecture of kidney.  He is a visiting scientist in the Murawala Lab at MDIBL, where he is learning the basis of tissue clearing and light-sheet microscopy which he wants to apply to African turquoise killifish (Nothobranchius furzeri).
