In the interview, Niedra tells us about her path to doctoral studies, the concept of her doctoral thesis, her study and research experience at RSU, as well as about her future career plans and advice for those considering pursuing doctoral studies.

Please tell us about the topic of your doctoral thesis – what is your research focus and why did you choose it?

At the moment, the topic of my doctoral thesis is quite broad – Bioactive natural products: from molecular insights to therapeutic innovations in antibacterial drug development. It involves obtaining natural bioactive substances through extraction and the physical and chemical analysis of the extracted material. This is followed by further development into appropriate forms – drug delivery systems. I chose this topic because medicinal plants are personally meaningful to me, and I try to use them in my everyday life to support my health. 

I believe that the potential of natural substances has not been fully explored and that they hold promise in future medicine. Natural antibacterial substances have a milder effect on the body’s microbiome and natural balance, so they have the potential to act preventively and in the long term.

What was your path to doctoral studies? What did you study before?

I completed a chemical technology programme at Riga Technical University and obtained a bachelor’s degree in engineering. I continued my master’s studies at the Faculty of Chemistry of the University of Latvia, focusing on analytical chemistry. I took the opportunity to spend six months on an exchange programme in an advanced instrumental techniques course at Umeå University in Sweden, where I gained valuable theoretical and practical knowledge working with various analytical chemistry methods. In 2024, I started working at the Laboratory of Finished Dosage Forms at the RSU Faculty of Pharmacy, which is fully equipped for conducting modern research.

What are the advantages, benefits, and challenges of studying and conducting research at RSU?

Studying at RSU offers the advantage of working alongside knowledgeable colleagues in the fields of pharmacy and medicine, which significantly broadens your horizons and opens opportunities for interdisciplinary collaboration. The benefits include the knowledge and practical skills gained through doctoral study courses, as well as access to an extensive network of scientific contacts.

Among the challenges, I can mention finding the time and resources required to conduct research.

Do you already have plans for your future career after your doctoral studies?

I would love to continue working at the Laboratory of Finished Dosage Forms, as it offers a multifaceted environment with strong opportunities for professional growth. I would also be happy to work with students and pass on my knowledge.

Who would you recommend pursuing doctoral studies to?

Doctoral studies are for those who are interested in exploring a particular field in greater depth, working with scientific literature, and discovering or proving something new.
