Prof Victor Houliston
Prof Victor Houliston, Research Professor in the Department of English, is an A-rated researcher at the University of the Free State (UFS).

The University of the Free State (UFS) has added another National Research Foundation (NRF) A1-rated researcher to its ranks with the appointment of Prof Victor Houliston, Research Professor in the Department of English. This brings the number of the university’s A1-rated researchers to three.

The university also boasts the first A2 rating in the field of arts in the person of Prof Willem Boshoff, a senior professor in the Department of Fine Arts within the Faculty of The Humanities and one of South Africa's foremost contemporary artists. The other scholars with an A1 rating are Prof Maxim Finkelstein, the distinguished Professor at the Department of Mathematical Statistics and Actuarial Science, and Prof Melanie Walker, Distinguished Research Professor and National Research Foundation (NRF) Chair in Higher Education and Human Development.

The A rating is for researchers regarded as world leaders in their fields. Prof Houliston received his rating in 2022 – three years after retiring from the University of the Witwatersrand (Wits).

Consistent research output

Prof Houliston, who is an authority on early modern British and Irish Catholic studies (religion and politics) and has also published on John Donne (especially his prose works and sermons) and Renaissance rhetoric, says there is no formula for receiving an A1 rating.

“The definition of an A-rated scholar is someone who has achieved a certain reputation in their field internationally. That comes from a consistent research output, building up a portfolio of work in a particular field and moving the debate along, so that you become the go-to person on that subject.

“There is that sense of focus and some shifting of the picture or debate or understanding in your field. In science, the evaluation of a person's standing is more straightforward; in the humanities, research has a more subjective element so one's work is more vulnerable to criticism. In my case, as my research has evolved from English literature into historical studies, it has entailed archival and linguistic groundwork which makes it a little more objective,” says Prof Houliston.

The importance of Robert Persons

It is hard to say whether he chose his specialism, or his specialism chose him: an unexpected request for help from Guy Butler in 1988 led to his investigating the life and career of Robert Persons, an English Jesuit from the time of Queen Elizabeth I. Over the intervening 30 years, this Catholic activist has become widely recognised as one of the most important figures in early modern European history.

Prof Houliston started with a re-interpretation of Persons' published works, culminating in a 2007 monograph, Catholic Resistance in Elizabethan England. He is now editing Persons' extensive multilingual correspondence, as the leader of an international team of experts. The second volume was published earlier this year, with a third in preparation. He is also working with a team of South African classicists to translate Persons' Latin publications.

"As with most research, we work from the known to the unknown, pushing back further into the primary material – the archive."

Prof Houliston says that as a researcher, one must jealously guard one's time, which is difficult because the demands of teaching and administration have become more burdensome. Most academics show great commitment and idealism when it comes to teaching, so they are reluctant to leave students to their own devices. Ironically, this often leads those who are on the A-rating trajectory to take refuge in specialised institutes or centres of excellence and stop teaching, which can be a loss to students.

Given space to do research 

“Lecturers at a university such as the UFS, with its goal of increasing its research productivity, need space to do research. Bureaucracy may have to retract a bit. Lecturers themselves have to learn where to draw the line,” he says.

"This may appear selfish, but it enhances the learning environment. If you were to ask students if they preferred to be in a university where high-quality research is taking place, they would likely say, 'Yes. That gives my degree greater credibility. I would want to feel that those who are teaching me are contributing to the increase of knowledge’.”

His advice to emerging researchers is to follow the advice of Stephen Covey, author of The 7 Habits of Highly Effective People: conduct a weekly review of how they are managing to integrate research into their daily life as academics. Most lecturers are in a position where they only do research during vacations, but they can challenge themselves to carve out more regular times for research.

No slowing down

“That idea of constant review is important so that you are always moving forward. Many people just give up, because research is more challenging than, say, answering your emails, and you need energy and time. So, if you can reduce that start-up cost by doing a little every day, and preferably at the beginning of every day, it will make all the difference.

“The UFS, and especially heads of departments, can help to create a culture where scholars and researchers feel part of an interactive community. We need to move beyond the system to a sense of vocation. We have a vocation as university lecturers, professors and scholars, and everything else is secondary to the pursuit of knowledge. The system is merely a tool,” says Prof Houliston.

With multiple large-scale research projects on the go, as well as workshops and writing retreats, he is now busier than ever, with no plans for slowing down. He says: “I recently hosted a workshop for colleagues planning to apply for rating, to optimise their applications. One of my briefs is to enhance the research communities within the English department and the Faculty of Humanities in general, and especially amongst younger researchers.”

You could say he is speeding up. He recently completed a master’s degree in creative writing. "It's never too late to discover how many bad writing habits I have developed over the years!"

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
