I’m currently a PhD student at the School of Pharmacy (UiO) with a background in mathematics. A travel grant from NORBIS, for which I’m grateful, enabled me to spend six months (January to June 2018) as Visiting Fellow at Cornell University in New York, USA. My main affiliation at Cornell was with the Department of Biological Statistics and Computational Biology (BSCB).

My PHD project and purpose of my stay
My PhD research focuses on the use of thyroid hormone replacement therapy (THRT) during pregnancy. The goal is to investigate whether THRT has effect on immediate birth outcomes. The project relies on the use of statistical methodologies and analysis tools. Hence the goal of my visit at Cornell was to spend time in a quantitative research environment renowned for the development of novel statistical methodologies.

The Department and Collaboration
I joined the research group of Professor Matteson early January, and felt very welcome by him, students, faculty members and administrative staff. I was immediately offered office space and the necessary research facilities. Professor Matteson and I agreed on regular meetings. These meetings created a forum for discussion, where I have had to answer questions that have contributed to deepen my own understanding of the project. Most challenging however, was explaining to a statistician with no background in pharmacoepidemiology what my research is about.

Outcomes of Visit
Our first collaborative project aimed to classify women according to similar patterns of medication use, and to compare these patterns across different data sources. We applied Group-based  trajectory models (GBTM) to the data and identified four disjoint groups of adherence patterns of medication use. The results were summarized in a manuscript, entitled ‘Group-based trajectory models to determine patterns from different data sources on maternal use of thyroid hormone replacement therapy’. This manuscript, submitted whiles at Cornell, is currently under review.
As an extension of this project, we have started work on quantifying the effect of THRT use on immediate pregnancy outcomes. Collaboration on this project will continue beyond my research visit.

Academic Seminars and Workshops
In addition to research, I attended weekly seminars at the department of statistics as well as took part in workshops on statistical methods, which was organized by the Cornell Statistical Consulting Unit (CSCU). Graduate students at the department usually present their latest research results during a bi-weekly seminar. I had the opportunity of presenting my research project during one of the seminar meetings in March.

Community engagement
Besides academia, I supported the Cornell University hockey team (the Big Red), during their their Ivy league hockey tournament. In April, I also participated as a panelist to share my career path experience with undergraduate students at Cornell University. In May, I got accepted to participate in a “Julie Tumbles Leadership retreat” workshop tailored specifically to young, female researchers and organized by CORNELL’S GRADUATE & PROFESSIONAL WOMEN’S NETWORK (GPWOMEN). The workshop discussed the obstacles women face during their career and how to deal with them.

In total, my six months stay abroad at the department of BSCB was very stimulating experience both personally and academically. So far it was the best and most rewarding experience during my PhD, and I’m grateful to NORBIS for making this possible. I can strongly recommend every PhD student to spend some time abroad.
