I am happy to announce this web application, designed to assist researchers working in pump-probe and time-resolved photoluminescence microscopy. This tool aims to make estimating the Contrast-to-Noise Ratio (CNR) for noisy 1-dimensional Gaussian profiles as simple and efficient as possible. It’s completely free to use.

Is There Any Escape From Noise?
Exciting news! Our latest research, now an Editor’s Pick in The Journal of Chemical Physics, unveils how even moderate experimental noise can dramatically skew the accuracy of measuring excited state diffusion in materials like perovskites. Delve into our findings and explore our new open-source tools designed to refine these measurements. Join us in advancing the precision of diffusion measurements.
The multilayered role of scientific posters
A simple question from a 9-year-old at a major scientific conference sparks a reflection on the significance of scientific posters. Delve into how these visual aids cater to diverse cognitive preferences, making research findings more accessible and inclusive.
The etymology and meaning of methyl, ethyl, propyl, butyl
Chemistry study often feels like learning a new language due to its extensive vocabulary. Understanding word origins can greatly improve memory retention. Early chemistry nomenclature includes memorizing roots like methyl, ethyl, propyl, and butyl, representing 1 to 4 carbon chains in functional groups. This article offers a thorough explanation for those studying or interested inContinue reading “The etymology and meaning of methyl, ethyl, propyl, butyl”
Penrose Tessellation Cookie Cutters
Over the holiday break, I took a little time for a side quest that engaged my creativity while involving mathematics, 3D modeling, and baking. I designed a pattern based on Penrose tiles and made it into cookies.

I’m a co-author of the following article, published in two parts in the China Coatings Journal:
Green chemistry seminar videos
Join the Portland, Oregon section of the American Chemical Society for a couple of wonderful talks on Green Chemistry. First, Dr. David Stuart, Assistant Professor of Chemistry at Portland State University, offers a brief introduction to Green Chemistry and an example from his lab. Next, Dr. Tom Wilson, retired Director of Materials Technology at Nike,Continue reading “Green chemistry seminar videos”
Portland ACS interview
The Portland section of the American Chemical Society interviewed me about my internship at NASA Glenn Research Center in Cleveland, Ohio in summer, 2015, where I worked on lithium-sulfur battery research. Read the interview here: Portland State chemistry student Joseph Thiebes loves materials science and explored battery technology during NASA internship
Diamond lattice structure pendant
Diamonds are a scam! They are common and worthless. One company has cornered the market, controlling how many diamonds are mined and how they reach the consumer. Mining for diamonds is back-breaking work, and the wages are ridiculously low. It is for this reason I have created the diamond lattice structure pendant. This pendant featuresContinue reading “Diamond lattice structure pendant”
Nobel Prize Laureate Eric Betzig
“I would never call myself a chemist,” said Nobel Prize in Chemistry 2014 recipient Eric Betzig. Betzig was the 2015 speaker at the annual Mark Gurevitch Memorial Lecture Series, hosted by the Physics Department at Portland State University. During his lecture at Hoffman Hall on May 14, Betzig spoke about his career and his prize-winningContinue reading “Nobel Prize Laureate Eric Betzig”
