Hannah Waterman is a scientist, educator, and mentor dedicated to translating complex research into insights that inspire curiosity, foster growth, and connect science to real-world impact. She is currently a Postdoctoral Associate at the Duke Molecular Physiology Institute, where she conducts mechanistic human clinical research under the mentorship of Jonathan Campbell, PhD, and David D’Alessio, MD. Her work focuses on how pancreatic α-cell signaling regulates β-cell function and hepatic insulin sensitivity across metabolic health and early type 2 diabetes, reframing glucagon biology as a dynamic and context-dependent regulator of human metabolism.

Hannah earned her Doctor of Philosophy (PhD) in Molecular Physiology and Biophysics from Vanderbilt University School of Medicine, where she trained in the laboratory of Alan Cherrington, PhD. Her doctoral research investigated the physiologic and cellular mechanisms underlying the second-meal phenomenon, demonstrating that morning insulin establishes hepatic metabolic “memory” that enhances later postprandial glucose uptake and glycogen storage through coordinated insulin-dependent and insulin-independent pathways. Her work integrated sophisticated metabolic physiology with molecular analyses, linking whole-body glucose regulation to cellular adaptation. This research resulted in multiple first-author publications, nearly 20 presentations at local, national, and international meetings, and recognition through prestigious awards, including the Vanderbilt Basic Sciences Dean’s Award for Exceptional Achievement and the Vanderbilt Diabetes Scholar Award.

She earned an Honors Bachelor of Science (BS) in Biochemistry & Molecular Biology and Mathematics from Linfield University, where she conducted independent research on regulation of the human PPARγ gene under the mentorship of Dr. Megan Bestwick. This work laid the foundation for her interest in metabolism, physiology, and translational science. During this time, she also gained hands-on industry experience as a laboratory intern and specimen processing specialist at Precision Analytical Inc.

Hannah’s path to science has been shaped by resilience, curiosity, and mentors who recognized her potential. Growing up disadvantaged in a rural town in Washington, she navigated many challenges independently while developing a deep love of learning. Identified early for her strengths in math and science, she pursued advanced coursework, balanced athletics and leadership roles, and actively sought research opportunities that ultimately shaped her scientific trajectory.

Alongside her research, Hannah is deeply committed to education and mentorship. She holds a Certificate in College Teaching with specializations in STEM and online education and has extensive experience tutoring and teaching across K–12 and higher education. She teaches Human Physiology courses for gifted students through Vanderbilt’s Programs for Talented Youth and has mentored numerous students and trainees, fostering curiosity, confidence, and growth.

Hannah is also the founder of The Metabolism Lab, a science communication and mentorship platform created to provide the clarity and guidance she wished she had earlier in her career. Through writing, educational content, and storytelling, the platform translates complex research in metabolism and physiology into accessible insights and supports learners navigating scientific paths. She is particularly committed to empowering young women and underrepresented voices in STEM.

For Hannah, science is not only about discovery. It is about connection, opportunity, and lifting others as you rise. Through her research, teaching, and The Metabolism Lab, she works to advance knowledge while creating pathways for others to succeed, inspiring curiosity, confidence, and a lifelong love of learning.
