Department of Biology

 LIFE is like a CARD GAME, your parents deal you a hand of 46 chromosomes rather than 52 cards, and then they determine how you play your hand with the quality of the home life & training they provide. So, in the game of life, it is your parents that are responsible for how you ultimately perform in life. Public schools & Universities can not replace your parents. They only facilitate and further your learning.

Research Interests

Areas of Interest:

Physiology, phylogeny and biochemistry of invertebrates and plants; physiological ecology; invertebrate physiology

Special interests are:

  • In (1) physiological ecology and (2) invertebrate physiology and biochemistry of freshwater and terrestrial molluscs and freshwater crustaceans -- most recently we have been studying the mechanism of calcium carbonate deposition in clam, crayfish, lobster, and crab shell
  • Calcium and strontium in shell formation have also been studied in both snails and ostracods
  • The phylogeny of both wild rice and phyllopods are also areas of interest

Courses Taught


BIO 1310: Modern Biology I
BIO 2430: Human Anatomy and Physiology
BIO 3421: Vertebrate Physiology: requirements are zoology & genetics. Vertebrate morphology is helpful. Botany and microbiology do not susbstitute for zoology.
BIO 4442/5442: Experimental Techniques
BIO 4450/5450: Physiological Ecology: this course is for biology majors who have had zoology, genetics, vertebrate physiology or A&P, and who seek to understand how animals are adapted to their environment. It's physiology and biochemistry that determine an organisms ecology.
