Xi Chen (Senior Staff Scientist)

Xi Chen did his BSc in Experimental Medicine in Peking University Health Science Centre in Beijing, where he became intereted in all the techqniues used in biochemistry and molecular biology. After graduatiion, he joined Prof. Andy Sharrocks' lab at the University of Manchester as a PhD student, studying the DNA binding specificity of different Forkhead transcription factors. During his PhD, he discovered an evolutionarily conserved transcription factor complex that regulates G2/M cell cycle transition. After his PhD, he joined Dr. Sarah Teichmann's group as a postdoc to investiage T helper cell 2 (Th2) differentiation from an epigenetic point of view.

He is currently working as a Senior Staff Scientist in the Teichmann lab, where he has been trying to develop techniques to interrogate the gene expression and epigentic profiles at the single cell level. He is manly interested in incorporating gene expression and epigenetic data to understand cellular differentiation.

Johan Henriksson

Johan obtained his master degrees in mechanical/software engineering and mathematics at Chalmers University of Technology (Sweden, 2007). After a master thesis on predicting NMR responses from gel structures, and working on mathematical modeling of sympatric speciation, he completely changed gears and entered biology instead. Johan did his PhD at Karolinska institutet (2012), developing microscopy software and hardware to study gene expression patterns during C.elegans embryogenesis.

Frustrated by the throughput limitations of microscopy, he is now developing methods for large-scale mapping of transcriptomic regulation - including CRISPR screenings and custom single-cell chemistries. His research is supported by a grant from the Swedish Research Council

After joining Teichmann lab, she has worked on understanding the relationship between chromatin state and stochastic gene expression at the single-cell level. She is also a member of Center for Therapeutic Target Validation team, where she uses single cell transciptomics to identify immune cells and molecules involved in asthma disease.


Bidesh Mahata

Bidesh is an experimental biologist who joined this group in 2011. He is passionate about his discovery of immune cell-mediated de novo steroidogenesis. He is determined to understand the (patho)physiological  importance of  de novo steroidogenic immune cells.

Bidesh obtained his PhD (Biochemistry) from Calcutta University, India, in 2008. Before joining this group he did his postdoctoral research at the University of Wisconsin-Madison and University of Dundee.

Kedar Natarajan

Kedar Natarajan is interested in leveraging single cell approaches to understand the interplay between cell cycle and gene expression during differentiation and cell fate choices. Kedar works predominantly with embryonic stem cells and also with T-helper cells using a combination of different experimental and computational approaches.

Kedar received his PhD from Imperial College London while working at MRC-Clinical Sciences Centre, London on systems biology approach to dissect chromatin proteome of RNA Polymerase II in embryonic stem cells. Before that, he obtained Masters and dual Bachelor's degree from India.

Jhuma obtained her PhD from Jadavpur University, India. She is studying T cell activation/differentiation. Specifically she is interested to understand the role of IRE1a-XBP1 pathway during T cell activation.

Sougata Roy

Originally from India, Sougata did his PhD from Canada in the area of molecular biology of circadian rhythms in algae. He joined the group during mid-2014 with an EIPOD fellowship. His main interest in the group is to combine click chemistry and biochemical techniques to study the biochemistry of the steroid pregnenolone in immune cell regulation and development.

Felipe Vieira Braga

Felipe Vieira Braga studied in Brazil, where he did his BSc in pharmacy. After that he moved to The Netherlands where he did his MSc at Radboud University Nijmegen and PhD at the University of Amsterdam.
