Career Timeline:

  • 2010-Present Assistant Professor, Department of Biology, Saint Michael’s College
  • 2008-2009 Assistant Professor, Div. of Basic Pharm. Sciences, Xavier Univ., Coll. of Pharmacy
  • 2007-2008 Assistant Professor, Department of Biology, Xavier University of Louisiana
  • 2005-2007 Postdoctoral Fellow, University of Washington, Otolaryngology Department
  • 2002-2004 Postdoctoral Fellow, Emory University, Biology Department
  • 1995-2002 Ph.D., Neuroscience Program, Ohio University
  • 1990-1994 B.A., Biology and Psychology Double Major, University of Delaware

Areas of Expertise:

Neurobiology / Neuroscience; Neuron Networks; Computer Modeling; Comparative Biology; Electrophysiology; Biophysical Modeling

Courses I Teach:

  • Communications in the Biological Sciences
  • Human and Comparative Anatomy
  • Introduction to Cell Biology and Genetics
  • Neurobiology

My recent scholarship involves both neurophysiology and computer modeling of biological processes. Through this experience, Saint Michael's College is now one of a relatively few institutions that offers in-class experiences recording from single neurons and small networks of neurons, as well as working with computer models of these same neurons.

2010 VPAA Summer Research Grants and two student grants, Saint Michael’s College

Recent Projects

Characterize the central pattern generator neurons and their synaptic connections of the heartbeat system of North American leeches.

Noteworthy Activities

I have mentored several undergraduate researchers on independent research projects, including Kristen Cowens, Danielle Shepard, and Amanda Willette.

Life Off Campus:

Outside Saint Michael's, I enjoy cycling, skiing, computer programming and music production.

Adam Weaver, associate professor of biology, recently collaborated with his former research student, Bryanna Evoy ’16, on a poster presentation, “Phase analysis in a reduced model of the leech heartbeat system,” which was presented in November 2016 at the Society for Neuroscience conference in San Diego, CA. The experiment behind the presentation was performed on a mathematical model of a network in the leech nervous system responsible for blood flow to determine the role of network properties in producing functional motor patterns.

Adam L. Weaver, assistant professor of biology spoke to the Neuroscience program at Middlebury College on Feb. 28. His topic was “Life-Sustaining Rhythm: Neuronal Analysis and Mathematical Models of the Leech Heartbeat System,” based on the work of his laboratory at Saint Michael’s investigating small networks of neurons called central pattern generators or “CPG’s” in order to gain insights from medicinal leeches on ways CPG’s affect nervous system functions and critical motor behaviors
