**Hillary Catherine Maddin** is a [Canadian](/source/Canadians) [paleontologist](/source/Paleontology) and [developmental biologist](/source/Developmental_biology) known for her work on development in extinct and extant [amphibians](/source/Amphibian). She is currently an associate professor in the Department of Earth Sciences at [Carleton University](/source/Carleton_University).

## Academic and professional background

Maddin obtained her B.Sc. in biology from the [University of Toronto](/source/University_of_Toronto) (1999-2004). She went on to also complete her M.Sc. degree at the University of Toronto (2004-2006) researching [caseid](/source/Caseidae) [synapsids](/source/Synapsid) under the supervision of [Robert Reisz](/source/Robert_R._Reisz), followed by a Ph.D. degree (2006-2011) exploring the morphology and evolution of [caecilians](/source/Caecilian) at the [University of Calgary](/source/University_of_Calgary) under the supervision of Anthony Russell and Jason Anderson.

Maddin was awarded the highly competitive NSERC postdoctoral fellowship,[1][2] which she used to fund a position at the [Museum of Comparative Zoology](/source/Museum_of_Comparative_Zoology) and [Harvard University](/source/Harvard_University) in [Cambridge, MA](/source/Cambridge,_Massachusetts) (2011-2013), where she was supervised by Jim Hanken and was subsequently awarded the prestigious Banting Postdoctoral Fellowship,[3][4] which she used to fund a position at Carleton University in [Ottawa, ON](/source/Ottawa) (2013-2015), where she was supervised by Claudia Schröder-Adams. Since then, she has held her current position as a faculty member at Carleton.

## Academic contributions

Maddin's research encompasses a wide range of topics, primarily related to developmental biology using amphibians as a model system and exploration of morphological and phylogenetic patterns of [Paleozoic](/source/Paleozoic) tetrapods. She has published on a variety of groups, including a variety of synapsids,[5][6][7][8][9][10][11] [temnospondyls](/source/Temnospondyli),[12][13][14] and [lepospondyls](/source/Lepospondyli).[15][16][17][18] Much of her research in this area is directed towards anatomy of the braincase and other internal structures,[19][20][21] which extends to her work on extant amphibians, primarily examining caecilians.[22][23][24][25][26][27] She has also published several studies on the [African clawed frog](/source/African_clawed_frog) and the [axolotl](/source/Axolotl), both a model study system.[28][29][30][31] Her research has been published in leading scientific journals, including [Biological Reviews](/source/Biological_Reviews), [Nature Communications](/source/Nature_Communications), and [Nature Ecology & Evolution](/source/Nature_Ecology_%26_Evolution). Maddin has contributed to the naming of several new extinct taxa, outlined below:

Maddin has received numerous federal- or provincial-level grant awards to fund her research, including an Early Researcher Award (ERA) from the Ontario provincial government ($100,000 CAD),[35] a New Frontiers in Research Fund (NFRF) award from the Canadian federal government ($250,000 CAD),[36][37] and an [NSERC](/source/Natural_Sciences_and_Engineering_Research_Council) Discovery Grant ($40,000 CAD),[38] and her lab's research has been covered by leading news outlets.[39][40][41] She also serves as one of three managing editors for the Journal of Vertebrate Paleontology.[42]
