ScholarGPS honours Prof Hendrik Swart as highly ranked scholar

04 June 2024 | Story Leonie Bolleurs | Photo Kaleidoscope Studios

ScholarGPS awarded Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS), Highly Ranked Scholar status.

ScholarGPS celebrates Highly Ranked Scholars™ for their performance in various fields, disciplines, and specialties. Prof Swart’s prolific publication record, the high impact of his work, and the outstanding quality of his scholarly contributions have placed him among the top 0,05% of all scholars worldwide.

Prof Swart received Highly Ranked Scholar status (Lifetime) for ranking 16th in the discipline of Phosphor. Highly Ranked Scholars™ – Lifetime refers to distinguished authors, including those who are currently active, retired, or deceased. These scholars are recognised for their exceptional lifetime scholarly contributions, placing them in the top 0,05% of all scholars. Their achievements are evaluated across four categories: overall (across all fields), within their specific field of study, within their particular discipline, and across all specialties they are associated with.

Additionally, Prof Swart received Highly Ranked Scholar status (prior five years) for ranking first in Condensed Matter Physics, 42nd in Physics, 155th in Sensor, 207th in Physical Science and Mathematics, and 969th in all fields.

Scientific profile and credibility

ScholarGPS is a California-based company that applies artificial intelligence, data mining, machine learning, and other data science techniques to its massive database of more than 200 million publications and 3 billion citations to rank more than 30 million scholars and 55 000 institutions worldwide. They categorise more than 200 million scholarly publications into specific academic specialties. These specialties are further organised into 177 disciplines and 14 overarching fields. As a result of this extensive classification effort, scholars who are considered highly ranked within their respective fields can now be identified with greater precision. This identification is done not only within each academic specialty, but also across disciplines and fields, providing a comprehensive view of scholarly achievement and expertise. This system allows for the identification of top scholars within various areas of academic research in a way that was not possible before.

Prof Swart, who is an NRF B1-rated researcher, currently also holds the SARChI Research Chair: Solid-state Luminescent and Advanced Materials (2023-2027). On receiving this award from ScholarGPS, he says it is always a privilege to be recognised as one of the top scholars in your specific field, especially at this late stage of his career.

Professionally, Prof Swart says this award may boost his scientific profile and credibility in the academic community, potentially leading to more collaborations and partnerships.

In the field of condensed matter physics, the impact of his work is specifically noteworthy in the study of defects and impurities within semiconductors, along with their practical applications in optoelectronic devices. Moreover, his significant contributions extend to understanding optical and electronic properties at the nanoscale, bearing implications for the development of semiconductor technology, including light-emitting diodes (LEDs), photovoltaic cells, and quantum dots.

Primarily focused on mentorship

He believes his successes in physics and advances in understanding the universe are the result of a combination of variables, including innovative research, collaboration and networking, mentorship, effective communication, persistence, and resilience. “I am primarily focused on mentorship, which is critical to developing the next generation of physicists and creating a supportive environment for learning and discovery, as well as conducting groundbreaking research and making novel discoveries that are critical to pushing the boundaries of physics. I am always searching for opportunities to collaborate with other scholars, both inside and outside my discipline, which will result in constructive exchange of ideas, interdisciplinary discoveries, and collective problem solving.”

Researcher uses NRF funding for studies to conserve plant and animal life

2017-04-18

It is difficult to survey all different types of
plants and animals and is therefore necessary to
choose one representative group. Butterflies are
relatively cheap and easy to sample. They are
known to be linked to specific habitats and to
respond to human pressures, such as farming.

Earth is the only planet we know of that contains life. The variety of different plants and animals is remarkable: from the giant whales that swim our oceans, to the tiny mosses that grow on the shaded sides of rocks. Many of these plants and animals are important to humans. For example, trees provide us with oxygen to breathe, bees pollinate our crops and owls control pests. More importantly though, we can tell a lot about society from the way it cares for nature. Humans are the custodians of the planet and the way we care for nature reflects the way we value life.

Dr Falko Buschke, Lecturer at the Centre for Environmental Management at the University of the Free State, is interested in understanding how the distribution of biodiversity [the variety of living things in nature] in time and space influences the way we should conserve and manage nature.

Earth is losing biodiversity faster than at any time in human history
The planet is losing biodiversity faster than at any time in human history. “There is an urgency to conserve plants and animals before they are lost forever. Nature is complex, so the way we study it should embrace this complexity. We should not rely on limited data on one type of species from one place and assume that it will also apply elsewhere. Instead, it is important that biodiversity research is comprehensive in the types of plants and animals while also considering that ecological and evolutionary processes vary through time and across geographic space,” he said.

To conduct his research, Dr Buschke uses a variety of research tools, including biological data surveyed directly from nature, spatial data from satellite remote sensing and geographic information systems databases, and data generated though custom-built computer simulations.

"There is an urgency to conserve
plants and animals before they
are lost forever."

Field work in the eastern Free State
Although parts of the eastern Free State are considered a global priority for biodiversity conservation, it is mainly privately owned commercial farmland. This means that it is important that plants and animals can survive despite living side by side with agricultural production.

“My project investigates whether the sandstone outcrops, known as inselbergs (island-mountains), are safe havens for plants and animals. Because it is difficult to survey all the different types of plants and animals, it is necessary to choose one representative group. That is where butterflies come in. Butterflies are relatively cheap and easy to sample. They are known to be linked to specific habitats and to respond to human pressures, such as farming,” he said. “Once this butterfly data is collected, it can be linked to satellite information on plant growth patterns. This will provide a clearer picture of whether plants and animals can persist side-by-side with commercial agriculture”.

Dr Buschke has just begun surveys that will carry on until the end of this year. “This 12-month project is funded under the Foundational Biodiversity Information Programme through the South African National Biodiversity Institute (SANBI) and the National Research Foundation (NRF).
