Reference excerpt

Richmond Sarpong (born April 23, 1974, in Bechem, Ghana) is a Ghanaian-American chemist who is the Henry Rapoport Professor of Chemistry at the University of California, Berkeley. Sarpong works on natural product total synthesis to better understand biological systems and allow for the development of novel therapeutics. He was awarded a Guggenheim Fellowship in 2017, and was elected to the American Academy of Arts and Sciences in 2020 and to the National Academy of Science in 2025. He serves on the editorial boards of Organic Syntheses, Accounts of Chemical Research and Synlett.

Early life Sarpong was born in Bechem, Ghana on April 23, 1974, and spent his early childhood in Bolgatanga. His mother is a teacher, and his father a medical doctor who also holds a master's degree in public health. It was during his childhood that Sarpong first became interested in chemistry, when he saw how effective the drug ivermectin was in combatting river blindness (onchocerciasis). Ivermectin was being distributed in Africa by Merck free of charge, and Sarpong's father worked with the World Health Organization to aid in the distribution of the drug. Sarpong got his hands on his father's copy of the Merck Index, an encyclopedia of chemicals, and spent his free time imagining how chemistry could change people's lives. In 1984, Sarpong's family moved to Livingstone, Zambia and later Lobatse, Botswana in 1986. In Zambia and Botswana, he saw the devastating impact of HIV/AIDS in Africa. In Botswana, Sarpong attended the Maru-a-Pula School, where he was introduced to organic chemistry by his teacher Dr. Ramakrishna. Having this additional mentor encouraged Sarpong to pursue a career in chemistry, despite having an offer from a premedical program at a British university.

Education and training Sarpong moved to the United States in 1991 to study chemistry at Macalester College. At Macalester, he conducted undergraduate research with Prof. Rebecca C. Hoye on the determination of absolute stereochemistry of organic molecules using the Mosher method. Sarpong graduated with his B.A. in chemistry in 1995. Sarpong then pursued graduate studies with Prof. Martin Semmelhack at Princeton University. In Prof. Semmelhack's laboratory, he worked on organic compounds containing the enediyne functional group that model the activity of the calicheamicin class of antibiotics. Sarpong received his Ph.D. in 2001. Sarpong moved to the California Institute of Technology where he joined the laboratory of Prof. Brian Stoltz as a UNCF-Pfizer Postdoctoral fellow. At Caltech, he worked alongside then-graduate student Neil Garg to complete the first total synthesis of the phosphate inhibitor dragmacidin D. Sarpong also developed a novel tandem Wolff/Cope rearrangement to synthesize fused ring molecules.

Research and career In 2004, Sarpong started his independent scientific career at the University of California, Berkeley as an assistant professor. He was promoted to associate professor in 2010 and full Professor in 2014. The Sarpong group specialize in the synthesis of bioactive organic molecules, with a focus on the natural products of flora and fauna. He has developed new synthesis strategies for alkaloids, a family of natural medicines that includes quinine and morphine. In particular, Sarpong is interested in natural product synthesis for the treatment of neurodegenerative diseases. In 2017, Sarpong delivered a talk at TEDx Berkeley entitled The face of disease in Sub-Saharan Africa, in which described the influences on his desire to pursue chemistry growing up in Africa, and also encouraged his audience to reevaluate their perceptions of disease in Africa. Sarpong is committed to improving diversity within the chemistry community, and has supported many scholars in the early stages of their academic careers.

Personal life Sarpong plays tennis in his free time. While attending Macalester College as an undergraduate, he set the 100-meter dash record. Sarpong's sister, Martha Sarpong, is a R&D Director and Project Leader at GlaxoSmithKline Pharmaceuticals.

Worked examples

Example 1 — a first encounter with Richmond Sarpong

Start with the simplest possible case. Write down what Richmond Sarpong claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Richmond Sarpong before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Richmond Sarpong ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Richmond Sarpong

In research: Richmond Sarpong appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Richmond Sarpong in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Richmond Sarpong is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1974 births, American people of Ghanaian descent, California Institute of Technology fellows, so understanding it makes those chapters shorter.
In everyday life: Look for Richmond Sarpong outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
