Our Team

Jette Lengefeld, PhD

Assistant Professor

Jette is a Assistant Professor at the University of Helsinki (Finland) since 2021 and at the Karolinska Institutet (Sweden) since in 2023. 

Jette did her graduate studies at the ETH Zurich (Switzerland) focusing on asymmetric cell division in the lab of Yves Barral. This work started her interest in stem cells. Jette performed her postdoctoral studies at the MIT (US) in the lab of Angelika Amon, where she discovered cellular enlargement as aging factor of blood stem cells. Her independent research team is investigating how blood stem cells fail to maintain their functions during aging and disease.


Soham Bharadwaj, M.Sc.

PhD student

Soham did his bachelor’s in Biotechnology from Guru Gobind Singh Indraprastha University (New Delhi, India), finishing 12th best of all India in his discipline. He pursued his master’s in Molecular and Cellular Biology from Ludwig Maximilians University (Munich, Germany). Scientifically, his interest lies in understanding how cells regulate their size and the implications of size regulation. In his free time, he loves to boulder, hike, and mingle with people.

Soham received a University-funded doctoral candidate position for 3 years by the Doctoral Programme in Biomedicine. Congratulations!


Daniel Davies, M.Sc.

PhD student

For his undergraduate honors degree, Daniel studied Molecular and Cellular Biology at the University of Glasgow (Scotland) . During the 3rd year, he spent a semester studying abroad at Yonsei University in South Korea. After completing his bachelor’s, Daniel moved to study at the University of Edinburgh, pursuing a master’s degree in Bioinformatics. His research interests revolve primarily around the biology of aging; understanding the underlying mechanisms that cause cellular aging, why these lead to the formation of age-associated diseases and how these can be manipulated in regenerative medicine.


Emilie Cerezo, PhD


Emilie did her academic studies in Toulouse (France). During her PhD, she worked on the regulation of ribosome biogenesis by the MAPK signaling pathway in the Henry/Henras lab, at the CBI. She has been attracted to the study of cellular aging since her early university years. She now wishes to elucidate the underlying mechanisms that connect changes in HSC size to their dysfunction during age-related diseases.


Isabella Hietavirta

Undergraduate student

Isabella is a Bachelor student at the University of Helsinki in Molecular Biosciences. She is primarily fascinated by cellular aging, mitochondria, and regenerative medicine and is fascinated by cellular rejuvenation.


Di Wu, B.Sc.

Incoming researcher

Di completed his undergraduate studies in Clinical Medicine at Hunan Normal University in Changsha, China. He then pursued a master’s degree in Internal Medicine from Fudan University in Shanghai, China. Di will join us in October 2023 to understand the relationship between cell size, aging and metabolism.

Yue Liu, B.Sc.

Incoming postdoc

Yue got her undergraduate honors degree in Chemical and Biomolecular Engineering at the Nanyang Technological University (Singapore). She pursued her Ph.D. in Chemical and Biomolecular Engineering and Medicine Engineering from the University of Pennsylvania (USA). During her Ph.D., she used a microfluidic approach to investigate thrombosis and hemostasis in the Diamond lab. She is now interested in using microfluidics to study how the size of human HSCs influences their cellular function.
