Chemistry – About /about ÎŢÓÇĘÓƵ ÎŢÓÇĘÓƵ, News and Special Events Tue, 03 Nov 2026 23:29:51 +0000 en-US hourly 1 https://wordpress.org/?v=7.1.4 Faculty Profile: Dave Vosburg /about/2026/10/28/faculty-profile-dave-vosburg/ Wed, 28 Oct 2026 22:01:15 +0000 /about/?p=15809 Dave Vosburg, Donald A. Strauss Professor of Chemistry, has been at the College since 2005. Inside the lab, Vosburg leads a group of molecule-making students and outside, he strives “to generally be a blessing” to the people around him on campus. Vosburg and his students seek to make medicinally useful molecules in new ways, especially in biomimetic ways, using chemistry that imitates how such molecules are believed to be formed naturally in plants. “In ideal cases, it almost seems like the molecules are making themselves!” he says. They also seek to use environmentally friendly methods that minimize waste, toxicity and hazards. “Some of our target molecules can be used to fight inflammation, bacteria, fungi or tuberculosis. Often we make molecules that no one else has ever made before!” Learn more about Vosburg, including what superpower he’d like to have and how he’d use it, in this Q-and-A.

What is your favorite part about your job and why?

I love being able to bring other fun parts of my life into my job, like caring about sustainability, loving J. R. R. Tolkien’s Middle-earth and listening to students’ questions about how science and religious belief can go together.

What is something people don’t understand about your job that you wish they did?

It is so cool when your students have made a new molecule that no one else has ever made before! Everything we learn about it is brand-new, and we possess the world’s supply of it!

If you could swap jobs with any other HMC employee for a day, who would it be and why?

I’d swap with someone from CIS with an awesome view from the fifth floor of Sprague. I love great window views.

If you could add anything to campus to improve the employee experience, what would it be?

An amazing new building that would offer fantastic views of what’s going on inside the building as well as views for those inside to see the world outside as a reminder of the impact of their work at Mudd.

What’s your favorite food/dish in the Hoch-Shanahan Dining Hall?

Shrimp tacos or fried plantains.

What HMC events have made you feel really connected to other HMC colleagues?

I feel most connected when colleagues share about things that don’t typically come up in normal conversation. For example, when new faculty members are introduced by the dean of faculty, we often get a fun fact about each new hire in their first faculty meeting. We also had an Office of Institutional Diversity series in which colleagues shared about their life journeys and what was important to their development as a person.

What is your favorite hobby, activity or creative outlet?

I love to follow collegiate sports, whether it’s CMS, Williams College (my alma mater) or the University of Michigan (where my parents met as grad students). Lately, I’ve been very into the CMS tennis teams, which have been featuring a lot of Mudders! CMS will be hosting the Division 3 NCAA Tennis Championships in Claremont next May, making it a must-see event!

What is the best piece of advice someone has given you, either in life or at work?

Always keep in mind who I’m really living and working for, advice I got from Colossians 3:23.

What is your most effective strategy for dealing with stress?

My top strategies for managing stress are: praying about it, getting exercise (like biking to and from work each day), and spending time with my family. All of those help and all of them together are definitely the best.

If you could have one superpower, what would it be and how would you use it at work?

I would like to talk with molecules (if they could think and talk) so I would know how they want to react in new ways. There’s so much I’d learn about chemistry and about the world!

Are you studying or learning something new?

I’m learning about New Zealand, as I’m going there for a sabbatical during the 2027–28 academic year.

What book or podcast are you enjoying right now?

I’m currently enjoying a poem by J. R. R. Tolkien called “Mythopoeia” (myth making). Tolkien’s reflections about creating new things are inspiring to me as a molecule maker.

What’s a fun fact about you?

I have several large Lord of the Rings LEGO sets in my HMC office, and they bring me joy. Come see them if you like! A couple of Mudd students pranked one of the sets a few years ago, and I have left some of the prank intact to remind me about them and their fun antics.

Beckman Scholars Explore Research at Harvey Mudd /about/2026/10/09/beckman-scholars-help-drive-research-at-harvey-mudd/ Fri, 09 Oct 2026 21:35:34 +0000 /about/?p=15712 A three-year grant from the Arnold and Mabel Beckman Foundation launched the Beckman Scholars Program (BSP) at ÎŢÓÇĘÓƵ in summer 2026. Supporting six undergraduate researchers through 2029, the program offers each scholar a $26,000 award package for student stipends, faculty mentorship and institutional resources over a 15-month commitment, spanning two full-time summer terms and academic year research.  

The 2026 Beckman Scholars are Jacob Sesate ’27, mentored by Lisette de Pillis, Norman F. Sprague Jr. Professor of Life Sciences and professor of mathematics, and Cami Tauro ’29, mentored by Maduka Ogba, assistant professor of chemistry.  

Throughout the program, scholars engage in regular check-ins with their mentors to develop their research, gain presentation and communication skills and access professional resources. The program highlights Harvey Mudd’s commitment to a high-touch environment where students work directly alongside faculty on meaningful scientific discovery.  

Tauro’s project, titled “Origins of substoichiometric loading of calcium bistriflimide in sulfur-fluoride exchange (SuFEx),” uses computational chemistry to investigate a high-yielding, environmentally friendly reaction. She and her fellow lab member Oliver Spaulding ’29 are using density functional theory to evaluate different potential reaction pathways, and their goal is to determine the operative mechanism. Pinpointing this will provide helpful insights, allowing for reaction optimization and establishing this reaction as reliable for synthesizing essential compounds for the pharmaceutical industry. 

For Tauro, having early research experience at a level typically reserved for graduate students is building critical skills and expanding future career paths. “Mudd is genuinely so unique. As students, we are the ones driving the research throughout the entire process,” Tauro said. “My labmate and I … lead everything, from initial background research to forming hypotheses, conducting experiments and interpreting our results.” 

Tauro also emphasized how much Ogba’s mentorship has shaped her plans. “The chemistry community is very collaborative, and being involved in this research has allowed me to meet mentors and build lasting connections,” she said. “I’ve been able to reach out to faculty to learn more about their work, access additional resources and discover what different academic and industry environments look like.” 

Sesate’s research on “A Validated Mathematical Model of ICI Therapy” introduces a streamlined, mathematical model of immune checkpoint inhibitor therapy. Designed to better evaluate both single and combination immunotherapies, the model offers a lightweight tool for researchers, biotech firms and clinical trial designers. It allows teams to simulate drug interactions, optimize dosing schedules and test mechanistic hypotheses before moving into human trials.  

For seniors, the program serves as a launching pad to apply advanced coursework to real-world problems.  

“All of the research I had done prior to this didn’t involve mathematics in the same way,” Sesate explained. “I decided I wanted hands-on experience applying the math I had learned in my classes. While I knew I liked research, I hadn’t yet had the chance to implement it in such a formal project. This program allowed me to put those skills into practice under guided mentorship. My mentor, Professor Lisette de Pillis, even helped me secure an opportunity to present at a conference in Arizona. Getting those kinds of opportunities is difficult without that level of support.”  

Sesate and Tauro will continue their research through summer 2027. Alongside their lab work, the pair is also organizing the Beckman Scholars Program Seminar Series set for spring 2027.

Vosburg Makes Green Chemistry Practices Accessible /about/2026/07/27/vosburg-makes-green-chemistry-practices-accessible/ Mon, 27 Jul 2026 21:26:35 +0000 /about/?p=15515 ÎŢÓÇĘÓƵ chemistry faculty have developed a framework for including green chemistry components, sustainability topics and practices in their classrooms, instructional labs and research programs. In , David Vosburg, Donald A. Strauss Professor of Chemistry, offers a comprehensive blueprint for organic chemistry laboratory instructors to create lab courses that are both scientifically rigorous and environmentally sustainable. The article also gives examples for how instructors might approach integrating green chemistry throughout the organic chemistry laboratory curriculum. 

“Instructors can promote a green chemistry mindset in their students simply by asking for every experiment: What was green? What could be greener?” says Vosburg. “By reimagining traditional protocols and substituting toxic chemicals, the approach builds a culture of environmental consciousness among the next generation of scientists.”

The article describes how the green emphasis begins the first time HMC students step into the laboratory. On day one, students are introduced to the United Nations Sustainable Development Goals, specifically those related to good health, quality education, clean water and responsible consumption. Students select a goal they care about and explicitly map out how their knowledge of chemistry can help achieve it. Students are trained to evaluate the efficiency of chemical reactions using standard green metrics, such as atom economy, the ratio of waste to desired product and process mass intensity. They also use industry-standard solvent-selection guides to actively identify which chemicals are recommended, problematic or hazardous.

One of the most immediate impacts of this comprehensive approach is the systematic elimination of highly toxic solvents. Chief among them is dichloromethane, a pervasive but hazardous volatile organic compound traditionally used for extractions and chromatography. By substituting this and other dangerous chemicals with greener alternatives like ethyl acetate, acetone and heptane, the laboratory drastically reduces health risks to students and instructors while minimizing hazardous waste. 

A continually evolving and expanding collection of highly innovative, eco-friendly chemical reactions are being developed or adapted for the curriculum at Harvey Mudd and shared with educators around the world. For instance, students have joined two molecules of vanillin (from vanilla beans) together in water using a natural enzyme in horseradish rather than relying on heavy-metal catalysts and organic solvents. Vosburg has even brought simplified versions of this divanillin synthesis into classroom demonstrations for high school and elementary school students. In other sessions, Harvey Mudd students have prepared the anticoagulant warfarin, the anesthetic lidocaine, the anti-anxiety drug moclobemide, and perfumes from rose or geranium oil using green chemistry techniques.

By giving students choices in their experimental pathways and involving them directly in curriculum design, they become active stakeholders in sustainable development.

Liesel Hilkemeyer ’27 says: “It has been really exciting to be part of the transition to greener labs and see the green chemistry theory we’ve learned about in the classroom actually applied, tangibly, in the lab. It is very rewarding to make our labs safer and greener.”

The significance of this educational shift extends beyond the College: Vosburg is part of a growing network of like-minded educators, the , and a related article from the Vosburg lab—with coauthors Angela Milo ’28, Lijinghan (Alice) Chen POM ’26 and Kyle Grice ’05—on “” already has over 22,000 views in just over a year. By limiting student exposure to dichloromethane and other toxic chemicals and encouraging curricular innovation, the program directly addresses global sustainability targets.

As chemical industries worldwide face increasing pressure to adopt circular, zero-waste practices, students trained under this blueprint will enter the workforce uniquely equipped to lead the transition. “Ultimately, our work is a reminder that building a sustainable future does not require sacrificing academic excellence; it simply requires asking how our chemistry can be greener,” Vosburg says.

Sarah Kavassalis Receives Seaver Institute’s Support for Native Plant and Urban Air Quality Research /about/2026/03/01/sarah-kavassalis-receives-seaver-foundation-support-for-native-plant-and-urban-air-quality-research/ Sun, 01 Mar 2026 18:28:04 +0000 /about/?p=15034 ÎŢÓÇĘÓƵ Professor of Climate and Chemistry, Sarah Kavassalis, was awarded a three-year grant from The Seaver Institute to support research on how emissions from native Southern California vegetation interact with urban air pollution. The award provides $70,000 per year to support the project, Understanding Biogenic VOC Emissions and Air Quality Impacts in Los Angeles’s Coastal Sage Scrub Ecosystem.

Kavassalis and the research team focus on solving an enduring challenge: Despite decades of progress to improve air quality, ozone pollution remains a persistent health risk to Southern Californians. They are examining how volatile organic compounds (VOCs) released by native plants, particularly California coastal sage scrub species, interact with nitrogen oxide pollution from transportation and industrial sources to influence ozone formation. The Los Angeles region was once covered by coastal sage scrub, but now it exists primarily in fragmented urban and coastal patches. These native ecosystems are critical for maintaining biodiversity and strengthening climate resilience.

Some native plants can emit highly reactive compounds that may accelerate ozone formation under certain urban conditions, especially during extreme heat. The team aims to identify when natural plant emissions do not meaningfully influence air quality, helping support restoration and urban greening efforts that protect both ecosystem health and community air quality. Their work could help reshape how native vegetation is incorporated into urban landscapes and may ensure that restoration and greening efforts deliver climate, water and biodiversity benefits to support healthier air for communities across Southern California.

The research connects atmospheric chemistry, plant ecology and policy, which can offer interdisciplinary opportunities that can exist even beyond the grant’s continuance. Field measurements will be conducted at the Bernard Field Station in Claremont, which hosts the only AmeriFlux tower in Los Angeles County. This tower, referred to as US-BFS, measures carbon and water exchange over the coastal sage scrub habitat. Laboratory analysis will be paired with ecosystem-scale measurements to build a more complete picture of how plant emissions respond to heat and droughts along with other common environmental drivers.

Kavassalis and the research team aim to identify distinct emission patterns among individual plants during the project period, quantify how these emissions affect the surrounding atmosphere and develop a public archive of coastal sage scrub VOC emissions for use in regional and state air quality modeling. A project goal is to produce easily digestible, culturally valued planting guidance to help cities and decision-makers select lower-emission plant variants while maintaining biodiversity and saving water.

The project provides hands-on experience in environmental chemistry, ecology and policy-relevant science, with undergraduate training incorporated throughout. The work is designed to support decision-making agencies, such as the California Air Resources Board and the South Coast Air Quality Management District, while contributing to broader efforts to understand urban air quality in a changing climate.

Adam Johnson Co-authors Chemistry Textbook Bridging Coursework and Research /about/2026/02/16/adam-johnson-co-authors-chemistry-textbook-bridging-coursework-and-research/ Mon, 16 Feb 2026 19:01:58 +0000 /about/?p=15051 Advanced undergraduate and first-year graduate students now have a modern pathway into high-level inorganic chemistry via the recently published textbook Inorganic Chemistry: An Integrated Approach, co-authored by Adam R. Johnson, a chemistry professor at ÎŢÓÇĘÓƵ.

Co-authors Johnson, Aaron L. Odom, Remi Beaulac, Mitch R. Smith, James K. McCusker and Chip Nataro designed the textbook to fill a longstanding gap in chemistry education: a single, cohesive resource that goes beyond introductory inorganic texts while remaining more accessible and pedagogically grounded than highly specialized graduate monographs.

“This book was designed to fill a niche where there haven’t been many options,” said Johnson, Ray and Mary Ingwersen Professor of Chemistry and chair of Harvey Mudd’s Department of Chemistry. “There are good introductory inorganic books, and there are good, advanced topic books, but not an advanced, comprehensive textbook that prepares students for research.”

A Decade-Long Collaboration Rooted in the Chemistry Community

The origins of the book trace back to an American Chemical Society (ACS) national meeting in San Diego 10 years ago, when Johnson was first approached by co-author and former graduate school colleague Aaron Odom about joining the project.
Johnson said, “We felt that having authors from both R1 and primarily undergraduate institutions would be a strong selling point for the text.”

Over time, the author list expanded to include leaders across multiple subdisciplines of inorganic chemistry. Johnson’s longtime collaborator Chip Nataro joined the project as well, building on nearly two decades of shared work on the teaching resource website ionicviper.org.

Research-driven, Current and Pedagogically Grounded

Johnson began researching his chapters shortly after that initial ACS meeting, with the bulk of the writing completed during the COVID-19 pandemic. He authored the chapters on organometallic chemistry, his primary research area, as well as bioinorganic chemistry, a field he worked in during his postdoctoral training at UC Berkeley.

“Relearning bioinorganic chemistry at a deeper level allowed me to see the similarities between the two fields,” Johnson said. “It really highlighted the importance of the local structure around a metal atom in dictating its reactivity. We have a lot to learn from biology, and these naturally evolved proteins improve our own ability to have such strong control over reactivity in a laboratory-synthesized metal complex.”

Across all chapters, the authors prioritized currency and connection to the primary literature. Johnson’s chapters include references through 2024—“as current as a textbook can be,” he noted. “We wanted students to see what inorganic chemistry actually looks like today.”

Bridging Coursework and Research

The book emphasizes the development of bonding theories that go beyond introductory chemistry, including ligand field theory and symmetry concepts taught alongside group theory and projection operators.

“This level of theory is important to explain chemical reactivity, structure and spectroscopy of metal complexes, which is what the majority of inorganic chemists study,” Johnson said. “But we also outline current research efforts across the discipline, from making new materials for gas separations, to catalysts to make pharmaceuticals, to understanding how platinum anticancer drugs work.”

Johnson particularly enjoyed writing about one of his favorite topics: molecular orbital theory. “This textbook has several chapters that build on knowledge from first-year chemistry to develop molecular orbital theory such that it can be applied to more complex systems. Then, the book uses this theory extensively to explain observed reactivity and spectroscopy.”

To support both instructors and students, the textbook includes advanced optional topics, extensive worked examples, end-of-chapter problems tied to the primary literature and a full answer key.

A Teaching Perspective Informed by PUI and R1 Faculty

Johnson believes the mix of perspectives among the authors is one of the book’s greatest strengths.

“Faculty at primarily undergraduate institutions tend to think deeply about teaching and pedagogy—how material is presented and received by students,” he said. “R1 faculty often focus more on research opportunities and pushing the frontiers of science. Having both perspectives in one book allows more breadth of how the material will be presented.”
