Julio C. de Paula

Professor of Chemistry

I am a Professor of Chemistry and a member of the Environmental Studies Steering Committee at Lewis & Clark College. I also co-direct, with Prof. Paulette Bierzychudek, the Pathways to Success in STEM Program.


I have taught courses in general chemistry, physical chemistry, inorganic chemistry, instrumental analysis, biophysical chemistry, bioinorganic chemistry, environmental chemistry, nanoscience, and writing.

I am currently teaching Perspectives in Environmental Chemistry (CHEM 100) and Physical Chemistry Laboratory (CHEM 365). In the fall of 2017 I will lead a lewis & Clark overseas program in Berlin, Germany.

Professional Experience

After 16 years at Haverford College, I moved to Lewis & Clark College in 2005. While on professional leave from 2010 to 2012, I was a Program Director in the Chemistry Division of the National Science Foundation.

I have received a Christian and Mary Lindback Award for Distinguished Teaching and a Henry Dreyfus Teacher-Scholar Award. In 2015 I was named a Cottrell Scholar by the Research Corporation for Science Advancement.


To date I have mentored 51 undergraduate students in research supported by over $3 million in single-investigator and collaborative grants. Current projects in my laboratory include:

  • Assembly and characterization of nanowires that conduct electricity when activated by solar radiation. Our hope is that these wires can lead to a new generation of solar energy conversion devices, such as environmental sensors, solar cells, solar paint, and optical computers.
  • Design and construction of inexpensive, solar-powered devices for water purification. Our goal is to provide point-of-use water purification stations to families without access to electricity.
  • Characterization of artifacts from archaeological sites. Working with collaborators at the University of Portland and the University of Barcelona, we are investigating soil, bones, and artifacts recovered from the ancient Roman city of Pollentia, just outside the current city of Alcudia, in Mallorca, Spain.

News from the de Paula group

  • Summer 2016: Taylor Hudson ’16 and I will participate in an archaeological research project in Mallorca, Spain. Teams of archaeologists, biologists, engineers, and chemists from the University of Portland, Lewis & Clark College, and the University of Barcelona will collaborate.
  • April 2016: Lauren Heald ’16 presented her research results at the Festival of Scholars, then successfully defended her thesis, and received Honors in Chemistry. She will begin graduate work at Arizona State University in the fall.
  • May 2015: Raymond Craddock ’15 and Henry Kreiman ’15 successfully defended their theses, and received Honors in Chemistry.
