Reference excerpt

Segenet Kelemu is an Ethiopian scientist, noted for her research as a molecular plant pathologist and her outstanding scientific leadership. For close to three decades, Segenet and her team's research has contributed to addressing agricultural constraints in Africa, Asia, Latin America and North America. From November 2013 - December 2023, Segenet was the Director General of the International Centre of Insect Physiology and Ecology, Africa's only institute dedicated to research on insects and other arthropods. Previously, she was the Director of Biosciences eastern and central Africa (BecA); Vice President of Programs at the Alliance for a Green Revolution in Africa (AGRA), and Leader of Crop and Agroecosystem Health Management at the International Center for Tropical Agriculture (CIAT). Segenet has received many international accolades including: the L'Oréal-UNESCO Awards for Women in Science in 2014; Fellow, TWAS − The World Academy of Sciences; honorary doctorate by Tel Aviv University, in May 2016; recognition as one of Forbes Africa top 100 most influential African women, in May 2014; mentioned as one of 10 most influential African women in agriculture by the Journal of Gender, Agriculture and Food Security (AgriGender Journal) and election as a Fellow of the African Academy of Sciences. Her other honours include: CIAT's Outstanding Senior Scientist Award; Friendship Award granted by the People's Republic of China and the TWAS Prize for Agricultural Sciences, by TWAS, The World Academy of Sciences.

Early life Segenet Kelemu was born in the Ethiopian town of Finote Selam. In school, Segenet, though prone to challenging and contradicting teachers, demonstrated self-determination and, above all, academic prowess. She was fortunate to have teachers who recognized and nurtured her potential. Like many other children in her village, Segenet was expected to help out with farming chores. Moreover, from an early age, she displayed a strong sense of responsibility, and as a result, her mother assigned her the task of selling farm produce in the market; certain that she would negotiate the best prices and keep the money safe. Thus, Kelemu learnt the hard truths about agriculture: its back breaking labour—especially for women, as well challenges to productivity, which placed people in her community in a constant struggle to meet minimum households food needs; but amidst all, the sector's potential. As a result, she felt a calling to seek solutions for agricultural constraints. Therefore, though an all-round top grade student, Segenet decided to dedicate herself to science and agriculture.

Education

In 1974, Segenet became the first woman from her region to join Addis Ababa University—where she was one of a handful girls in a class of 200—graduating, on top of her class, with a Bachelor's degree in 1979. She then relocated to the US. At Montana State University, she earned a master's degree in plant pathology and genetics in 1985. She subsequently attended Kansas State University, earning a PhD in molecular biology and plant pathology in 1989. Her PhD thesis was "Molecular cloning and characterization of an avirulence gene from Xanthomonas campestris pv. oryzae". Kelemu undertook postdoctoral research on the molecular determinants of pathogenesis at Cornell University from 1989 to 1992.

Career Between 1992 and 2007, Segenet worked at the International Center for Tropical Agriculture (CIAT), Colombia, first as a Senior Scientist, and later Leader of Crop and Agroecosystem Health Management. Her research focused on elucidation of molecular determinants of host-pathogen interactions, development of novel plant disease control strategies including genetic engineering, biopesticides, pathogen population genetics and dynamics, endophytic microbes and their role in plant development. In August 2007, Segenet decided to return to Africa, determined to contribute her experience in applying cutting-edge science to developmental issues, towards resolving the continent's problem. She accepted a position as the Director of the Biosciences eastern and central Africa (BecA) Hub. Under her leadership, the BecA initiative was transformed from a contentious idea into a driving force that is changing the face of African biosciences. BecA's research capacity, staff, facilities, funding, partners and training programs have expanded at an ever accelerating pace. She has assembled and inspired a scientific and technical team bound by a common passion for using science to enhance Africa's biosciences development. In 2013, Kelemu joined the Alliance for a Green Revolution in Africa (AGRA) as Vice President for Programs for about a year. In November 2013, Segenet became the Director General of the International Centre of Insect Physiology and Ecology (ICIPE), Africa's only institution dedicated to research on insects and other arthropods, which is headquartered in Nairobi, Kenya. She is the fourth chief executive and the first woman to head the institution. In January 2018, Segenet was singled out by philanthropist Bill Gates as one of five "heroes [whose] lives inspire me".

Worked examples

Example 1 — a first encounter with Segenet Kelemu

Start with the simplest possible case. Write down what Segenet Kelemu 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 Segenet Kelemu 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 Segenet Kelemu 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 Segenet Kelemu

In research: Segenet Kelemu 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 Segenet Kelemu 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: Segenet Kelemu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 20th-century women scientists, 21st-century agronomists, so understanding it makes those chapters shorter.
In everyday life: Look for Segenet Kelemu 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.
