Prof Maxim Finkelstein, distinguished Professor at the Department of Mathematical Statistics and Actuarial Science at the UFS has become the only researcher with an A1-rating in South Africa (awarded by NRF) in Probability, Statistics and Operations Research.

A professor in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) has become the only researcher with an A1-rating in Probability, Statistics and Operations Research in South Africa after being awarded this prestigious rating by the National Research Foundation (NRF).

This is the second time Prof Maxim Finkelstein, the distinguished Professor at the Department of Mathematical Statistics and Actuarial Science in the Faculty of Natural and Agricultural Sciences, has been awarded with an A-rating. The first was in 2015.

The goal is to produce quality research

According to Prof Finkelstein, the rating should not be a goal as such for a researcher but should produce a quality research that is recognised by peers and that, above all, brings a real satisfaction in life. Prof Finkelstein says: “The rating is just a consequence of what one, as a researcher, has achieved in the past eight years and, actually, during the whole professional life as well. South Africa is the only country in the world that is able to perform this rigorous internationally sound rating process for individual researchers. ‘Scientifically large’ countries just cannot do it, technically.”

Prof Finkelstein’s area of expertise is the modelling of random events and quantifying probabilities of their occurrences. He explains: “For instance, in industry, people are interested in probabilities that a machine or process or mission will accomplish its task without failure or accident. In order to assess the probabilities of interest, one must have an adequate mathematical/stochastic model that should be properly developed. 

“Thus, I am developing such models that can be rather advanced because they should take into account numerous factors, e.g., that the object is operating in a random environment, that its structure could change, that there can be human errors affecting the outcome, that an object interacts with other objects, etc. This is usually done in the framework of mathematical reliability theory that considers operation of technical devices.” 

The only A-rating at NAS

“I am quite excited to get the A-rating for the second time, especially because it is the only A-rating in Probability, Statistics and Operations Research in South Africa. It is also the only A-rating at our Faculty of Natural and Agricultural Sciences.

“The fact that it is an A1 and not A2, as previously, does not, in fact, mean too much to me. What matters really is that it is the A-category defined by the reviewers’ opinions that the applicant is a world leader in his discipline,” says Prof Finkelstein.

During his numerous visits as a research professor to the Max Planck Institute of Demographic Research in Germany, he jointly with the colleagues from this institute, were applying the developed stochastic approaches to modelling lifespans of organisms as well. 

One of Prof Finkelstein’s evolving interests is in the area of healthcare engineering when, for instance, monitoring the key health parameters of a patient, some optimal cost-wise decisions can be made on preventive treatments and interventions. 

“I want also to stress that, in general, international collaboration is very important for emerging and established researchers, especially in ‘remote’ South Africa, although nowadays the term ‘remote’ is obviously outdated,” says Prof Finkelstein.

He also collaborates with numerous colleagues around the globe. Apart from the visiting position in the Max Planck Institute he held for many years, Prof Finkelstein regularly visits the ITMO University in St Petersburg, Russia, and is also now establishing a Visiting Professor position at the University of Strathclyde in Glasgow, Scotland.

#Women'sMonth: Long hours in wind and cold weather help to reconstruct Marion Island’s glacial history

Liezel Rudolph, a lecturer for second-year students in Process Geomorphology, aims to reconstruct the glacial history of Marion Island through cosmogenic nuclide dating techniques. She is interested in periglacial geomorphology, a study of how the earth’s surface could be formed by ice actions (freezing and thawing of ice).

Liezel is a lecturer in the Department of Geography at the university and is researching landscape development specifically in cold environments such as Antarctica, the Sub-Antarctic islands, and high mountain areas. “My involvement with periglacial geomorphology is largely due to academic giants who have carved a pathway for South Africans,” says Liezel.

Liezel visited Marion Island for the first time during her honours year in 2011, when she investigated the impact of seals on soil conditions and vegetation. Three years later, she visited Antarctica to study rock glaciers.

The challenge of the job
A workday in Antarctica is challenging. “Our time in the field is very limited, so you have to work every possible hour when the weather is not life-threatening: from collecting soil samples, to measuring soil temperature and downloading data, we measure polygons and test the hardness of rocks. The only way to get the amount of work done, is to work long hours in wind and rain with a positive and competent team! We take turns with chores: the person carrying the notebook is usually the coldest, while the rest of us are stretching acrobatically over rocks to get every nook and cranny measured and documented.”

A typical workday
Liezel describes a typical workday: “Your day starts with a stiff breakfast (bacon and eggs and a bowl of oats) and great coffee! After that comes the twenty-minute dressing session: first a tight-fitting under-layer, a middle layer – sweater and T-shirt, and then the outer windbreaker (or a quilt jacket on an extra cold day). Then you start applying sunscreen to every bit of open face area. Beanie on, sunglasses, two pairs of socks, two pairs of gloves. The few kilograms of equipment, one vacuum flask containing an energy drink, one vacuum flask containing drinking water (it would freeze in a regular bottle), and a chocolate bar and piece of biltong for lunch. After this, we drive (on snowmobiles) or fly (in helicopter) to our study area for about eight hours of digging, measuring, downloading, testing and chopping. Back at the base and after a long and tiresome undressing session, we move to the lab with all our data to make sure that it is downloaded safely and captured onto a database. Afterwards, depending on the day of the week, we enjoy a good meal. If you are lucky, such a typical day will coincide with your shower day. We can only shower every second day due to the energy-intensive water production (we have to melt snow) and the sewage system (all the water has to be purified before it could be returned to the environment). Then you grab your eye shield (since the sun is not sinking during summer) and take a nap before the sun continues to shine into the next day.”

Theoretical knowledge broadened 
“Going into the field (whether island or mountains) provides me with an opportunity to test geomorphic theories. Without experience in the field, my knowledge will only be limited to book knowledge. With practical experience, I hope to broaden my knowledge so that I could train my students from experience rather than from a textbook,” says Liezel.
