Postcard from Edinburgh: Tina Košuta From Roslin Institute

Written by: Tina Košuta

A nine-week research visit to the Roslin Institute at the University of Edinburgh under the mentorship of Dr. Gregor Gorjanc and Dr. Daniel Tolhurst was an immensely valuable research and personal experience for me. During the visit, I researched the data augmentation method for parameter estimation in linear mixed models. I began my work with a literature review and the implementation of existing approaches, after which Dr. Daniel Tolhurst and I explored options for applying and further developing the methodology for complex linear mixed models used in the field of genetics. Such models often involve very large datasets and intricate covariance matrix structures, presenting a major computational challenge. The goal of the research is to develop more efficient approaches for model parameter estimation, thereby enabling data analyses that are difficult or impossible to perform with currently available computer hardware.

I actively participated in weekly research group meetings, where we presented research results, discussed methodological questions, and sought solutions to ongoing research challenges. Collaborating with established researchers was highly motivating and gave me a better understanding of various research career paths and the development of an international scientific career. Following the conclusion of the visit, we will continue our collaboration remotely. The visit contributed significantly to my development as a researcher, expanded my professional knowledge, and allowed me to establish valuable international research connections.

After completing the research visit, I went on a one-week trip around Scotland with my family. Our route took us first through the Scottish Highlands, then along the west coast to the town of Oban, and back toward Stirling and Edinburgh. Along the way, we saw the beautiful Scottish landscape, sheep, and cattle, and met many friendly people.

In addition to my research work, I also enjoyed exploring Edinburgh and Scottish culture. The experience of living and working in an international environment will remain a lasting memory, and above all, I am grateful for the opportunity to collaborate with top-tier researchers from whom I learned a great deal, both professionally and personally. I look forward to continued collaboration with the team at the Roslin Institute.
