Kerstin is interested in understanding the regulation of gene expression in health and disease. Kerstin did her undergraduate degree in Biochemistry at Imperial College, London, followed by a PhD in immunology at the MRC Laboratory of Molecular Biology. Since then she has worked at the University of Cambridge studying aspects of gene regulation in immunology and gene regulatory networks in breast and lung cancer. Her appointments have included a Royal Society University Research Fellowship and a Group Leader position at the Department of Oncology. She is currently co-ordinating the Human Cell Atlas efforts at the Sanger Institute.

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.


Lira Mamanova (Research Manager)

Lira manages the 'wet lab' side of the research group. She was previously working in Sequencing R&D.



Tzachi Hagai

Tzachi's scientific interests lie in the intersection of evolution, regulation and protein biophysics.

In recent years, he has focused on host–virus co-evolution and interactions as a model for studying the evolution of protein–protein interactions and gene regulation. 

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

Gozde Kar

Gozde did her PhD at Koc University, Istanbul, Turkey where she has specialized in structural bioinformatics and performed large-scale computational studies on protein recognition. 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.

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.

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. Felipe specializes in studying the human immune system, with special interest in human cytotoxic lymphocytes (T and NK cells). During his PhD he worked on transcription and metabolic regulation of primary CD8 T-cells. At the Teichmann Lab Felipe uses single cell technologies to understand the heterogeneity of the human T-cell compartment and how this heterogeneity can improve our understanding of immune responses against pathogens in humans. Additionaly, Felipe is part of the Centre for Therapeutic Target validation, where he uses single cell technologies to identify new therapeutic targets for treating Asthma.
