Dan R. Halm

Dan R. Halm, Ph.D., is an Associate Professor in the Department of Neuroscience, Cell Biology, and Physiology at Wright State University's College of Science and Mathematics. He received his doctorate from the University of Iowa in 1981. His laboratory investigates epithelial physiology with a focus on ion transport mechanisms in the gastrointestinal tract.

Research in Dr. Halm's lab examines:

• Neural and hormonal regulation of ion secretion (Cl⁻, K⁺, H⁺) in intestinal epithelia
• Compartmentalized cAMP signaling pathways controlling transient vs. sustained secretion
• Ion channel function (BK, KVLQT, inwardly rectifying K⁺ channels) in health and disease
• Pathophysiological mechanisms in cystic fibrosis, IBD, and IBS

Techniques include patch-clamp electrophysiology, transepithelial current measurement, RT-PCR, immunoblotting, immunohistochemistry, and live-cell imaging.

His publication trends (15 most recent) demonstrate:

• Consistent focus on potassium/chloride secretion mechanisms in distal colon
• Expertise in adrenergic/neuropeptide receptor signaling (β-adrenergic, Y2 receptors)
• Integration of electrophysiological, molecular, and biochemical approaches
• Use of guinea pig and mouse models for epithelial transport studies

No scientific awards, student advisees, or grant information is mentioned in the provided text. The lab's work aims to develop therapeutic approaches for gastrointestinal disorders through fundamental research on epithelial transport regulation.
