BIOGRAPHY

  • Principal investigator of a bromate modeling project in a closed seawater system
  • researched inorganic ozonation by-products in seawater
  • collaborated with scientific and management personnel at The Living Seas aquarium to maintain the chemical balances in the system
  • analyzed interstitial water from estuarine sediments for a variety of parameters
  • produced computer models for maintaining (1) seawater ratios of major ions, and (2) pH and alkalinity in artificial seawater systems
  • analyzing seawater chemistry in a variety of closed systems
  • conducting studies on bay water chemistry in Great Bay, New Jersey

 

EDUCATION

Ph.D., M.S., Florida Institute of Technology
B.S., Lehigh University

AREAS OF EXPERTISE

Seawater aquarium chemistry, redox processes, interstitial water, physical and chemical modeling of closed seawater systems.

COURSES TAUGHT

Program teaching: Introduction to Oceanography, Oceanography II, Marine Chemistry Laboratory and Analysis of Seawater and Sediments
General Studies teaching: The World Ocean and Our Living Planet


RESEARCH INTERESTS

I lead a research group in Marine Chemistry. The basis of our work is chemical analysis of samples from a variety of marine environments. Our laboratory is located at the Nacote Creek Field Station. Ongoing projects include measurements of salinity (chlorinity), pH, alkalinity and major seawater ions for the local estuarine waters. Field work in Great Bay includes sampling of sediments and analysis of sediment pore water for sulfide, sulfate, ammonia, pH, redox potential and other parameters.
