Lab Members


Dr. James Monaghan is the principal investigator and an assistant professor of biology. He received his BA from DePauw University and his PhD from the University of Kentucky. He joined Northeastern University in 2012.

Dr. Ester Comellas is a postdoctoral researcher at the Shefelbine and Monaghan groups. She investigates the mechanobiology of joint formation using axolotl and computational models. Dr. Comellas received her PhD from Universitat Politècnica de Catalunya.

Anastasia Yandulskaya is a fifth-year graduate student. Her research project focuses on retinal regeneration in the axolotl. She received her BA in Neuroscience from Colgate University in 2016.

Alex Lovely is a fifth-year graduate student investigating the early role of epithelium in limb regeneration. He has helped established the use of V3 HCR FISH in the axolotl and worked at Northeastern’s Chemical Imaging for Living Systems Center. Alex holds a BS in Biology (’16) from Northeastern University.

Tim Duerr is a fourth-year graduate student. He studies limb patterning, nerve dependency of limb regeneration, and mechanobiology of joint formation. Tim earned his BS in Biology from SUNY Cortland in 2017.

Ari Lechsinska is a second-year graduate student. Her project investigates the role of nerves in axolotl limb regeneration. She received her BS in Biology from the University at Albany in 2017.

Jackson “Jebediah” Griffiths is a first-year graduate student. He researches nerve dependency in limb regeneration, hypertranscription, lung regeneration, and application of V3 HCR FISH to mouse and human tissues. He has a BA in Cell and Molecular Biology (’19) from Northeastern University.

Samantha Johnson is a BS/MS student. She studies the role of nerves in regeneration of axolotl limbs.
