How the Art of Baking Satisfies the Need for Science


Guest Post by Dr. Danny Welsch

Dr. Danny Welsch is the Associate Dean of the School of STEM at APUS. His article addresses some of the science that can be observed through baking and cooking.

I never thought I’d be a scientist. When I was a kid, I wanted to be a chef. My mom was always cooking and baking, and she taught me a lot about preparing healthy and delicious foods, mostly from scratch. I grew up helping her in the kitchen and gradually became more independent in my cooking. I got to the point where I would cook breakfast for the whole family every morning throughout high school, and I took a lot of pride in that.

When I went to college in the mountains of western Maryland, I didn’t know what to study. I was an accounting major for a while, but then I discovered that by studying the environment, I could spend a lot more time outside. And that’s where it started – I chose science because I liked being in the mountains, caves, and streams of Western Maryland, where I still live today. But I never lost my love for cooking and baking.

When I graduated with my bachelor’s degree, my first job was working the night shift for a geographic information system (GIS) firm, converting paper military maps into a digital format. Working at night meant that I was home a lot during the day, when no one else was. Earlier that year, I found an old book titled A World of Baking by Dolores Casella in my grandmother’s basement. In the hours before my shift digitizing maps would begin, I baked bread – a lot of bread – with the recipes from this book. I was still living with my parents at the time, and my Mom was worried about how much bread we were all eating.

Fast-forward a few years to graduate school, and the time to cook creatively was pretty limited. That time was taken up by the fun and stimulating activities associated with becoming a scientist: researching, analyzing, field and lab work, writing computer code, and writing about it.

When I graduated from the University of Virginia with my doctorate, I followed a traditional academic pathway, becoming an assistant professor at a regional public university. Now that I was a fully-fledged, practicing, and published scientist, I began to see the overlaps between science and cooking. Both require creativity, research, experimentation, observation, analysis, and modification to the technique. Both are intellectually stimulating and “scratch the itch” of solving tough, complicated problems in unique ways.

Fast-forward a few more years, and I find myself as an academic administrator (Associate Dean for the School of STEM). In this role, I still get to solve problems and be creative, but in a different way. I realized that I was missing doing science, so I turned back to baking.

Baking can be very complicated, but I’ve been approaching it in a simple way – three ingredients. Flour, water, and salt are all you need to make a wonderfully tasty loaf of bread. Notice that yeast is missing from that ingredient list, and this is where things venture into the realm of science.

The baking I’ve been doing lately is all with natural yeasts, also called sourdough. The yeasts come from a microbial culture, or “starter,” in the language of bakers. My kids have named my starter Barnaby, because he is alive and lives in our fridge. He gets fed flour and water every few days, so he is always ready to make a loaf. It can be pretty easy to make a good sourdough, but things can also go very wrong. Understanding the science of the process helps to make a consistently good bread, which I’ve been doing several times a week now for the last few years. In fact, if we run out, my family gets upset! And since it takes two days to make a loaf, I have to plan ahead to ensure we are always in bread.

Baking sourdough bread and really working on understanding the science behind it (and there’s a lot!) has helped fill the gap that is left by not doing as much actual science as I once did. Understanding the physical changes that occur during an autolyze (the chemical changes that occur from the fermentation of the starter), the microbial processes occurring as the microbial culture metabolizes the carbohydrates, and the differences that changing the baking temperature and conditions can make has really been satisfying in a way that used to be met by my research. And my family and friends benefit from my successful (and failed) experiments!



Wally Boston Dr. Wallace E. Boston was appointed President and Chief Executive Officer of American Public University System (APUS) and its parent company, American Public Education, Inc. (APEI) in July 2004. He joined APUS as its Executive Vice President and Chief Financial Officer in 2002. In September 2019, Dr. Boston retired as CEO of APEI and retired as APUS President in August 2020. Dr. Boston guided APUS through its successful initial accreditation with the Higher Learning Commission of the North Central Association in 2006 and ten-year reaccreditation in 2011. In November 2007, he led APEI to an initial public offering on the NASDAQ Exchange. For four years from 2009 through 2012, APEI was ranked in Forbes' Top 10 list of America's Best Small Public Companies. During his tenure as president, APUS grew to over 85,000 students, 200 degree and certificate programs, and approximately 100,000 alumni. While serving as APEI CEO and APUS President, Dr. Boston was a board member of APEI, APUS, Hondros College of Nursing, and Fidelis, Inc. Dr. Boston continues to serve as a member of the Board of Advisors of the National Institute for Learning Outcomes Assessment (NILOA), a member of the Board of Overseers of the University of Pennsylvania’s Graduate School of Education, and as a member of the board of New Horizons Worldwide. He has authored and co-authored papers on the topic of online post-secondary student retention, and is a frequent speaker on the impact of technology on higher education. Dr. Boston is a past Treasurer of the Board of Trustees of the McDonogh School, a private K-12 school in Baltimore. In his career prior to APEI and APUS, Dr. Boston served as either CFO, COO, or CEO of Meridian Healthcare, Manor Healthcare, Neighborcare Pharmacies, and Sun Healthcare Group. Dr. Boston is a Certified Public Accountant, Certified Management Accountant, and Chartered Global Management Accountant. He earned an A.B. degree in History from Duke University, an MBA in Marketing and Accounting from Tulane University’s Freeman School of Business Administration, and a Doctorate in Higher Education Management from the University of Pennsylvania’s Graduate School of Education. In 2008, the Board of Trustees of APUS awarded him a Doctorate in Business Administration, honoris causa, and, in April 2017, also bestowed him with the title President Emeritus. In August 2020, the Board of Trustees of APUS appointed him Trustee Emeritus. In November 2020, the Board of Trustees announced that the APUS School of Business would be renamed the Dr. Wallace E Boston School of Business in recognition of Dr. Boston's service to the university. Dr. Boston lives with his family in Austin, Texas.
