Professor Dipti Talaulikar

MBBS, FRACP, PhD, FRCPA
Visiting Fellow

Associate Professor Dipti Talaulikar is a visiting fellow in the ACRF Department of Cancer Biology and Therapeutics at The John Curtin School of Medical Research, ANU, Canberra. She leads the Haematology Translational Research Unit at Canberra Hospital with a research focus on lymphoproliferative disorders. Her research program supports research students, and her particular areas of interest lie in dissecting the disease heterogeneity and determining the cellular origin of lymphoma using a combination of sophisticated flow cytometry and cell sorting, next generation sequencing and ultra deep sequencing techniques, establishing links between autoimmunity and lymphoma and determining mechanisms of spread of lymphoproliferative disorders to extranodal tissues especially the bone marrow.
 

Correlative studies for the NHL29 ALLG multicentre clinical trial are being performed by the group.
 

She manages the Haematology Research Tissue Bank, which is a repository of peripheral blood, bone marrow and primary tissue samples from patients with haematological and related disorders. A particular strength of the tissue bank is availability of cryopreserved cells for cellular analysis and creation of live cell model systems. Cell pellets, plasma, trizol preparations and paraffin embedded tissue are also available.  Our goal is to utilise this resource to promote research within Australia and internationally, and we welcome applications on quality scientific projects from researchers.

Current projects:

1.     Disease heterogeneity in NHL

2.     BCR and somatic mutations in patients with lymphoma and autoimmunity

3.     Characterising the plasma cell compartment in Waldenstrom Macroglobulinaemia

4.     Mutations in ribosome biogenesis and MDS

 

Research interests

Cellular origin of lymphoma: Recent studies have elucidated recurrent somatic mutations in several subtypes of non-Hodgkin lymphoma. However, it is not yet known at what stage in ontogeny these mutations arise. Our group is studying the disease heterogeneity within subtypes of non-Hodgkin lymphoma using sophisticated multicolour flow cytometry, genotyping and ultra deep sequencing techniques. The project involves use of human samples archived in the Haematology research tissue bank, and direct translation of research findings into the diagnostic laboratory and clinic.

Other projects include elucidation of links between autoimmunity and lymphoma, and mechanisms of spread of lymphoma cells to extra nodal tissues especially bone marrow.
