Thomas C. O'Haver

Professor Emeritus

Department of Chemistry and Biochemistry
University of Maryland at College Park

B.S. Chemistry, 1963, Spring Hill College

Ph.D., Analytical Chemistry, 1968, Univ. of Florida (J. D. Winefordner)

Professional Interests

My work was in the area of analytical spectroscopy and instrumentation development; derivative and wavelength modulation spectroscopy; continuum-source simultaneous multielement atomic absorption spectrometry; microcomputer applications in science education; diode-array spectroscopy; digital signal processing; science education; applications of constructivist pedagogy in science education.

In retirement, I continue to develop tutorials and software for signal processing and interactive simulation software modules for science instruction.  I have also done technology training for adults through School-based Inservice Workshops for Teachers and Adult Education Courses on technology-related topics.

Publications and Presentations
Approximately 100 journal papers and book chapters; over 200 seminars and talks presented at national and international meetings. Click here for my academic Curriculum Vitae. Since retirement, my wife and I have developed and presented a number of workshops for teachers on the applications of educational technology and Adult Education Courses on technology-related topics. I am a regular contributor to the Matlab File Exchange, where I am ranked in the top 1% of authors.

National Awards and Distinctions
Tour Speaker for the Spectroscopy Society of Canada, 1979.
Tour Speaker for the American Chemical Society, 1980 and 1981.
Strock Award from the Society of Applied Spectroscopy for research on continuum-source atomic absorption spectrometry, 1988.
EDUCOM/NCRIPTAL awards for Best Design and for Best Chemistry software, for software program SPECTRUM, 1990.

Science-related Web-based projects

Interactive Computer Models for Analytical Chemistry Instruction 

Signal Processing Tools for Scientists and Engineers

Introduction to Signal Processing in Chemical Analysis

ElectroSim: Electronic Circuit Simulations

Online material for chemistry courses I have developed and taught

On-line conferences

I organized the first CHEMCONF on-line conference during the summer of 1993. 450 participants used Listserv e-mail to discuss fifteen papers, which were available on FTP and Gopher servers. All subsequent conferences have been Web-based. Participation has approximately doubled since the first CHEMCONF, and the frequency of the on-line conferences, now called CONFCHEM, has expanded to several per year.  Press coverage:
