First publication in graduate school: highlighting opportunities and gaps in our understanding of gut microbial chemistry as it relates to nutrition, pharmacology, toxicology

Excited to have my first publication in graduate school! Published recently in Science Magazine, this is a review article I wrote with my adviser, Emily Balskus, and a senior graduate student in the lab. The article discusses the incredibly exciting topic of how gut microbes degrade the molecules we ingest (food, drugs, pollutants) and thus impact our overall health. This article will give you a sense of the topics I work on in graduate school and also will lay out the many opportunities and challenges that we face as a field. Overall, the article is a nice representation of my academic work at the interface between chemistry, microbiology, and nutrition.

Here is the nice overview written by the editors at Science:

One person’s meat is another’s poison

The human gut is packed with actively metabolizing microorganisms. These have a transformative effect on what we ingest—whether food, drugs, or pollutants. Koppel et al. review the distinguishing features of microbial xenobiotic metabolism, its interaction with somatic metabolism, and interindividual variation. Depending on the functional composition of microorganisms in the gut, the subsequent products may have nutritionally beneficial effects, modify pharmaceuticals, or be toxic. All of these consequences of our companion microbes can have important impacts on human health and well-being.

Young Chefs and NAHSSP 2017

We just wrapped up another fantastic set of Young Chefs Program: From Cooking to Science workshops! We spent the last two days with the teachers and students part of the Harvard Medical School Native American High School Summer Science Program (   This program brings high school students and teachers from the Hopi and Fort Peck Reservations to Harvard University for three weeks of college-level science education. The focus is to communicate science concepts as it relate to their everyday lives and to empower students to become change-makers in their own communities. Naturally, two years ago we added a cooking-science component to engage students with the chemistry, biology, and physics of the kitchen. 

This year we had 14 students and 4 chaperones from the two communities. We first learned about the molecular solubility and neuroscience of capsaicin, the spicy molecule in chili peppers. Extracting this molecule into butter, we showed that it is hydrophobic and then used the spicy butter for a creative shrimp cocktail. The second day we spent learning about the physics of polymers and how their properties shape the texture of food. We made tortillas from scratch and measured their elasticity to quantify the perfect texture. The tortillas eventually became vehicles for delicious lobster tacos.

We were inspired by the Young Chefs chili and tortilla lesson plans, which you can find here:

One of the most rewarding and fun teaching experiences this year! We are excited to continue this tradition every year!

Collaboration between Young Chefs and East Boston YMCA featured by America’s Test Kitchen

We are excited to see Cook’s Science of America’s Test Kitchen feature the amazing collaboration between Young Chefs Program: From Cooking to Science and East Boston YMCA that brought our hands-on curriculum tot he East Boston community. Thanks to all the volunteers who made this possible.
