James D. Angstadt

James D. Angstadt is a Full Professor of Biology at Siena University, serving continuously since 1991 with promotions from Assistant to Associate to Full Professor. He maintains dual academic appointments through summer faculty positions at the Marine Biological Laboratory since 2008.

His educational background includes:

• Ph.D. in Neuroscience, University of Wisconsin Madison (1986)
• B.S. in Biology magna cum laude, Juniata College (1980)

Dr. Angstadt's research program investigates cellular neurophysiology using the medicinal leech as a model system, focusing on ion channel mechanisms underlying neural excitability, synaptic transmission, and rhythmic motor behaviors. His electrophysiological and molecular approaches examine postinhibitory rebound, circadian rhythms, and neuromodulation, consistently involving undergraduate researchers in hands-on laboratory work.

Analysis of his 15 most recent publications reveals persistent investigation of ion channel properties (particularly potassium and sodium channels) and their modulation by neurotransmitters like serotonin and dopamine. His work demonstrates how specific ionic conductances generate neural oscillations and motor patterns, contributing significantly to cellular neuroscience and invertebrate neuroethology.

His principal recognition includes:

• Raymond C. Kennedy Excellence in Scholarship Award (2022)

Dr. Angstadt actively mentors undergraduate researchers in his laboratory while teaching Neurobiology and General Biology courses. His teaching philosophy emphasizes experiential learning through integrated laboratory components, and he has received multiple nominations for Siena's Jerome Walton Excellence in Teaching Award reflecting his commitment to student development.

He directs an active research laboratory at Siena University where students conduct electrophysiological recordings and molecular analyses to investigate neural mechanisms in leech preparations, maintaining this productive undergraduate research environment for over three decades.
