We Kickstart the new year by welcoming our new BSc. students this semester; Elísa Sól Oddgeirsdóttir, Ester Borgarsdóttir, Magnús Arnar Rúnarsson, and Mariya Petrova Monova. 

Elísa will be working alongside Mahtab to characterize the potential interactions between HMG-A and DNA using single-molecule FRET (sm-FRET). Magnús’s research focuses on FoxA1, its oncogenic mutations, and their effects on biophysical properties with Kristinn.

Ester will take on the histone expression, purification, and octamer assembly with Kinga and focuses on setting up a streamlined octamer production in our lab. Last, but not least, Mariya will be focusing on creating nucleosome arrays to study the binding of PU1 to larger chromatin structures using sm-FRET with guidance from Sigríður.

We wish them all the best for their projects!
