Letian Zhang


I completed my PhD at Karolinska Institute in 2023 and recently joined Bartosovic lab as a postdoctoral researcher. My research focuses on developing new single-cell epigenetic methods and their application in studying neurological development and diseases. In my spare time, I like playing badminton and swimming. During the summer, I immerse myself in the natural beauty of Sweden, exploring its captivating landscapes.

José Ramón Barcenas Walls (Pepe)

PhD Student

Hej! I am José Ramón and I am currently a 1st year PhD student in Neurochemistry with Molecular Neurobiology at SU.

I´m interested to learn more of the chromatin field, specially on how epigenetics and genome regulation directs different cell fates and functions, and how disregulation could contribute to diseases. 

In my free time I am learning Swedish, reading novels, I love baking and craft beer brewing, and recently I am playing squash or badminton if I´m not hitting the gym!


Yiquan Lu

Master Student - ScilifeLab Methods in Life Sciences programme

I am Yiquan and I am currently in my second-year study in the master's program Molecular Techniques in Life Science. I joined Bartosovic's lab as a summer internship student, and I will continue to finish my master's thesis project here. My research work mainly applies computational data analysis and visualization in single-cell epigenomics and then explains cell differentiation process during human brain development.

In my spare time, I like photography, traveling, and listening to music.
