Our people

Dr James Baty

Dr James Baty has been a Research Fellow at The Malaghan Institute since 2009. He completed a PhD on the signalling functions of naturally occurring oxidants in cells at the University of Otago Christchurch School of Medicine and Health Sciences thirteen years ago. Today, he is a key researcher in our Cancer Cell Biology group. 

Dr Baty also works at the Victoria University of Wellington School of Biological Sciences to study various aspects of insect life in New Zealand.


Research interests

I investigate the phenomenon of mitochondrial transfer, alongside Professor Mike Berridge. I am inspired by our ultimate aim, which is to understand cancer biology to create treatments and preventions. I enjoy the everyday learning and problem solving of research, and working with my colleagues to achieve common goals.

I also work with Victoria University of Wellington to improve the health of bees and research ways to limit the spread of invasive insects in New Zealand.

Research projects

Our group wants to answer two questions – does mitochondrial transfer occur in bone marrow transplant patients and is there transfer in brain tumour models? On a day-to-day basis, I use the technology available at the Malaghan Institute to detect changes in the DNA or RNA of tumour cells. Changes to the amount of mitochondrial DNA, or to the sequence, can indicate that a cell has received mitochondria.

We are trying to determine whether mitochondrial transfer occurs normally to repair damaged cells, and if it happens in other types of cancer. If we discover that this process is a key to cancer progression, an entirely new avenue of cancer therapies could be unlocked.

I use similar molecular techniques to study insect samples at Victoria University. However, these are to answer very different questions, such as whether there is evidence of a viral infection.
