Starting my journey as a researcher has been a whirlwind experience filled with ups and downs, revelations, and unexpected turns. Since graduating with my Master’s in Pharmacy in 2018, I’ve found myself immersed in the vibrant intersection of science and practical application. My passion for natural science subjects during school drew me into the pharmaceutical industry, but I quickly realized that traditional pharmacy work didn’t align with my aspirations.

Initially, I ventured into the realm of hospital pharmacy, where I had the unique opportunity to tour nearly every ward of TYKS hospital as substitute for the regular pharmacists during their vacations and leave. This experience was fascinating yet challenging; I was tasked with ensuring the safety of patients’ medications and guiding healthcare personnel on medicinal products. The hands-on experience of preparing IV mixtures and being part of a dynamic healthcare environment deepened my appreciation for the intricacies of pharmaceuticals. Yet, I felt a pull towards research—a calling that grew stronger with time.

Into the industry

My next step took me to Orion Pharma, where I worked as a research assistant in their R&D department, focusing on novel tablet formulations. Unfortunately, change negotiations led to my fixed-term contract not being extended. This was a pivotal moment; instead of feeling defeated, I remained hopeful and open to new opportunities. Just when I needed it most, a position as a formulation scientist at DelSiTech emerged, marking a significant turning point in my career.

Since joining DelSiTech in November 2020, my path has been anything but linear. I started as aformulation scientist, transitioned to a business associate role, and returned to my research roots by embarking on a PhD project in collaboration with the University of Turku. Through the ImmuDocs Pilot program, I began my doctoral journey in January 2025, focusing on immune responses of avian influenza A virus vaccinations.

From mice to maternity leave

Before my maternity leave in May 2025, I completed a six-week mouse study, immunizing 40 mice with H5-antigen derived from avian influenza. The goal was to compare humoral and cell-mediated immune responses between different dosing regimens. The initial findings indicated robust IgG responses in the silica groups, utilizing sustained antigen release via DelSiTech™ Silica Matrix Technology coupled with adjuvant incorporation, may enhance immunogenicity and overall vaccine effectiveness, suggesting that DelSiTech’s technology outperforms traditional bolus injections. While I eagerly await the results of the cell-mediated response analysis from frozen splenocytes, I am grateful for the progress made so far.

Work-life balance,a deligthful challenge

Balancing a budding research career with family life—two young children, a 2-year-old and an 8-month-old—has been a delightful challenge. Navigating home renovations and contemplating the possibility of adding a dog to our family keeps life exciting! I try to carve out time for my hobbies, including dancing, choral singing, and even learning navigation for boating this summer.

Reflecting on my journey, I am reminded that the path of a young researcher is not without its challenges. Yet, each experience shapes my perspective and fuels my passion for scientific discovery. I embrace the unpredictability of research and remain committed to making meaningful contributions to the field, all while cherishing the precious moments with my family. As I continue on this path, I find hope and excitement for what lies ahead, both in my research and personal life.
