David D. Ku, Ph.D.


DKu

Professor of Pharmacology and Toxicology

Education:

BA (1972) in Chemistry, Whittier College (Whittier, CA)

PhD (1976) in Pharmacology, Michigan State University.

Honors and Awards:

American Institute of Chemists Award (1972), NIH (HLBI) Young Investigator Research Award (1978), NIH (HLBI) Research Career Development Award (1984); Fellow of the AHA (2001 -) and the APS (CV section, 2002 -); Chair (2002-2004) and Past Chair (2004-2006) of the ASPET Division of Cardiovascular Pharmacology; Michigan State University KE Moore Distinguished Alumnus Award (2002); Honorary Professor of Pharmacology, University of Hong Kong Faculty of Medicine (2007-).

Research Interests:

Coronary physiology and pharmacology.  Regulation of coronary endothelial function and vasomotor tone.  And, the role of endothelial pertubations in various pathological states, including ischemia, hypertension and hypertrophy.

More recently we have also extended our vascular biology research into various natural products and botanicals. In particular, we have received both AHA and NIH fundings to investigate the vasoprotective effects of garlic against the development of pulmonary hypertension. We are undertaking integrative approach (from molecular to whole animals) as well as state-of-the-art LC-ESI-Mass Spectrometry method to identify and quantify various active ingredients found in garlic and correlate them to its vasoprotective effects in animals.
