2026 YIM Honorees
January 2026 – Mikaela Hukkanen

Congratulations to Mikaela Hukkanen for her recent first author publication in 

Hukkanen, M., Kankaanpää, A., Heikkinen, A. et al.Epigenetic aging and lifespan reflect reproductive history in the Finnish Twin Cohort. Nat Commun 17, 44 (2026).

Mikaela is a doctoral researcher in the Ollikainen, Kaprio, and Cristofari groups.

April 2025 - Feiyi Wang

Congratulations to Feiyi Wang for her recent first author publication in 

Wang F, Liu A, Yang Z, Vartiainen P, Jukarainen S, Koskela S, Oram R, Allen L, Ritari J, Partanen J; FinnGen; Perola M, Tuomi T, Ganna A. Effects of parental autoimmune diseases on type 1 diabetes in offspring can be partially explained by HLA and non-HLA polymorphisms. Cell Genom. 2025 Apr 25:100854. doi: 10.1016/j.xgen.2025.100854.

Feiyi is a doctoral researcher under the supervision of Andrea Ganna and Tiinamaija Tuomi at FIMM, University of Helsinki. Her PhD research focuses on the genetic risk and familial aggregation of autoimmune diseases, particularly type 1 diabetes and multiple sclerosis. In her recent publication, she investigates the associations between T1D in offspring and 50 parental autoimmune diseases, including epidemiological analyses using FinRegistry, a comprehensive Finnish nationwide registry dataset, and genetic analyses using the FinnGen study, partitioning the genetic risk into HLA and non-HLA components. In this paper, she also proposes a parental polygenic score that properly integrates both HLA and non-HLA contributions to improve the prediction of T1D risk in offspring. This work represents the main focus of her PhD research, and she is scheduled to defend her thesis on June 16.
