Prof Tomas Vetrik, Professor in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), recently delivered his inaugural lecture on the Bloemfontein Campus.

His research area is graph theory, and he mainly focuses on the degree-diameter problem, graph indices, and metric dimension of graphs.

Research focus

According to Prof Vetrik, mathematics was always his favourite subject in school. He also excelled in maths at university and decided to enrol for a course on graph theory while working on his master’s degree. “I liked it, so I also chose topics from graph theory for my PhD thesis,” he says.

In 2014, at the age of 32, he was appointed Associate Professor at the UFS, after postdoctoral research at the University of KwaZulu-Natal and working at the University of Pretoria. An NRF-rated researcher, he has published close to 75 research papers, a third of that as a single author in some of the most well-known journals in his area. Moreover, he was also research supervisor of three PhD and three master’s students.

International collaborations

In the eight years since his appointment at the UFS, Prof Vetrik has made research visits to universities from 14 different countries that have invited him for research collaborations. 

“I am often overseas. I like working from different places. It is interesting to me, and it helps me to be productive,” says Prof Vetrik, explaining some of the inspiration behind his mathematical ideas.

In the next two years, he would like to study more general mathematical problems beyond his current research area.

He says he is addicted to his research. “It overshadows all my other interests.” 

On the rare occasion when he is not working on his research, Prof Vetrik states that he has to keep himself busy. Unable to relax and do nothing, he likes to do sports of some kind or to travel. 

“I am a simple person. I do not even have a TV at home. I use an old-fashioned mobile phone that cannot access the internet,” he says.

Conductor: Nicholas Nikolaidis
Date: 1 March 2012
Venue: Odeion
Time: 19:30

The OSM opening concert 2012 with the OSM CAMERATA will be streamed live on the internet with the generous support of OSM partner, LA MUSE AUDIO & LIGHTING (www.ufs.ac.za/ufslivestreaming) in collaboration with the UFS LIVE STREAMING UNIT.

The OSM Camerata is going to shine in the very first annual OSM opening concert. The ensemble will be conducted by Nicholas Nikolaidis. The programme includes excerpts from Stabat Mater (Pergolesi), Romanian Folk Dances (Bartók), Pelimannit (Rautavaara), Elegy (Grové) and Purple Haze (Hendrix). since 2011, the Odeion School of Music has embarked on a new, innovative strategy striving towards uncompromising excellence and internationalisation, which includes the A-List scholarship programme and a new flagship chamber ensemble, the OSM Camerata. Talented South African, conductor/tenor Nicholas Nicolaidis, (runner-up in the First National Len van Zyl Orchestral Conducting Competition) will take the stage for the inaugural concert of the OSM.

Nicholas started his conducting career at an early age while still in the Drakensberg Boys’ Choir School. Professionally his first conducting post was as choirmaster and conductor of the choir and band at Pridwin Preparatory School (Melrose, Johannesburg) in 1996.

Following his appointment in April 1997 as the Musical Director of Côr Meibion Cymru de Affrig (The Welsh Male Voice Choir of South Africa), he conducted the choir for seven years, producing three albums. One of the highlights was the performance at the Royal Albert Hall in London in October 2000 for the Millennium Festival of Male Voice Choirs.

His orchestral conducting debut was in 1998 at the Johannesburg City Hall where he conducted the Johannesburg Festival Orchestra and the Symphony Choir of Johannesburg in a few items of ‘Last Night of the Proms’. Selected conducting performances include the Chanticleer Singers in a performance of Schubert’s Mass in G at the Holy Trinity Church (Braamfontein, Johannesburg) in 2002, and the Johannesburg Camerata, a chamber orchestra consisting of talented young performers, during their winter season in 2005.

In 2006, Nicholas enrolled at Stellenbosch University for a Master’s degree in Choral Conducting under the direction of the Norwegian pedagogue, Kåre Hanken. During this time, he also conducted the Johannesburg-based chamber choir, Collegium Vocale. He conducted the Johannesburg Chamber Wind Ensemble from 2006 to 2008.

In 2009, he conducted the Johannesburg Festival Orchestra in a programme of music by Leroy Anderson, the vocal ensemble, In Verse, and the Chanticleer Singers during their Christmas season. Nicholas was also the winner of the inaugural Young Choral Conductors Competition held during the Stellenbosch International Choral Conducting Symposium in March 2009.

In February 2010, he was awarded the Silver Medal in the inaugural Len van Zyl Conducting Competition held in conjunction with the Cape Philharmonic Orchestra. During the Easter period of 2010 he conducted Cantamus Corde in a performance of JS Bach’s St John’s Passion, whilst also singing the role of the Evangelist.

Nicholas has also appeared as guest conductor of the Philharmonia Choir of Cape Town in a concert with music by Ramirez and Klatzow. In that year he also conducted the gala Concert of the Brooklyn Theatre (Pretoria).

Refreshments will be on sale before and after the concert.
