Our Leadership Team

Our Strategic Leadership Team (SLT) is a future-focused group responsible for enacting the strategy and vision of NSW Health Pathology and overseeing the delivery of quality, customer-focused pathology and forensic and analytical science services to customers and patients across NSW.



Tracey McCosker PSM, Chief Executive

I’ve been the Chief Executive at NSW Health Pathology since December 2012. Prior to this, I was the Director of Clinical Operations at Hunter New England Health and have worked in public health for many decades. I was attracted to the role after being asked to prepare a business model for an integrated statewide public pathology service for the Director General of NSW Health at the time. The exercise convinced me this was an exciting proposition that would bring a lot of value to NSW Health and the broader community we serve.

Pathology is a critical clinical service that is important at all stages of life, including before we are born and after we die. I love leading and working with clever, capable and committed teams who consistently demonstrate our RITE values (Respect, Integrity, Teamwork and Excellence), and our caring, connecting and pioneering spirit.

Tammy Boone, Director, Corporate Governance

I have been with NSW Health Pathology since 2018. Prior to that, I held a range of legal roles in the public and private sectors, including a 10-year stint with CSIRO. I was attracted to the role as I saw a unique opportunity to apply my legal skills and knowledge in a field I am passionate about and deeply committed to.Every day is different, unpredictable, and presents an opportunity for me to learn something new.

 Stephen Braye

Dr Stephen Braye, Chief Medical Information Officer and Executive Director Statewide Clinical Services

I joined NSW Health Pathology in mid-2016 and prior to this I worked at Pathology North, Hunter Area Pathology Service (HAPS) and John Hunter Hospital’s Anatomical Pathology Department. It’s a real privilege to work with a team who are committed to reshaping the way public pathology services are delivered across NSW.

We are leading the way in testing and adopting emerging technology to span physical and geographical boundaries, and our goal is to be trusted leaders in connecting partners and communities to better care and outcomes.

Martin Canova, Executive Director, Strategy and Transformation

I started with NSW Health Pathology in March 2020. Previously, I was the Director of Transformation at Transport for NSW, leading organisational transformation. I have 20 years’ health experience as a clinician, healthcare consultant and health manager. I’m absolutely thrilled to be working at NSW Health Pathology with such a great team doing such exciting work. This role appealed to me because of the diversity, and the opportunity to drive transformational change across pathology. My passion is leading improvement of our health services for our patients, communities and staff.

I have led large scale change across healthcare sector in both government and private organisation in Australia, the Middle East and South East Asia
. I really enjoy working with a talented and motivated team and across a broad group of stakeholders. It’s really rewarding knowing the work my portfolio is delivering will improve the way pathology services are delivered and there will be a positive impact on patients, our staff and the broader healthcare sector. 

Paul Dunn

Paul Dunn, Executive Director, Finance and Corporate Services

I have been in this role since September 2019. Previously, I was Chief Financial Officer at the University of Newcastle for over four years, and before that, I spent 30 years with BHP/BHP Billiton in various roles and locations in Australia and Singapore. I was attracted to the role having heard lots of positive things from friends about the workplace culture and what NSW Health Pathology was trying to achieve. I was drawn to working for a large and complex organisation and there was the important option of being based in Newcastle; my hometown, and where my family and I were keen to stay.

I find new industries compelling and health/pathology is no exception, with many complex challenges and idiosyncrasies. The finance and accounting aspects may be common across sectors, but the application of those principles in different types of businesses, and the learning curves presented by an unfamiliar business model are very interesting. 

 Deanna Paulin

Dr Deanna Paulin, Executive Director, People and Culture

I joined NSW Health Pathology in August 2020. Prior to this role, I was the Organisational Performance and Leadership Practice Leader at the Nous Group since 2010, supporting executives, managers and employees through complex and challenging business and cultural change. 

I was really attracted to the vision and culture of NSW Health Pathology, and that this role allows me to work with, and support, all the dedicated and talented people across pathology, particularly at this important time during the COVID-19 pandemic. 

I love being able to work across strategic, operational and tactical initiatives, and that I can continue my passion and commitment to developing the culture and capability of the health workforce into the future, to ultimately improve people’s lives.


Rob Lindeman

Professor Rob Lindeman, Executive Director, Clinical Operations

I have been in this role since July 2016. Before joining NSWHP, I was the Clinical Director of the Department of Haematology at Prince of Wales Randwick. I was attracted to the role because I believe that public pathology is more effective when it functions as a single statewide service and I was keen to play a part in setting the strategic direction for this structure. 

I enjoy responding to operational requirements and acting as an interface to clinical colleagues and Local Health Districts (LHDs). My role allows me to participate in strategic planning, implementation of service improvements and day-to-day interaction with pathologists, the people who provide services in our laboratories and clinical and LHD partners.

Vanessa Thomson, Executive Director, Scientific and Technical 

I have been in this role since mid-2019. Prior to this, I was the acting laboratory manager at a NSW Health Pathology laboratory, and I spent over 10 years working in private pathology in Australia largely in management roles and about 20 years in pathology in New Zealand. I was looking for a new challenge and hoped that with my skill set and experience I could make a difference at a strategic level. I also wanted to be an advocate for the scientific and technical community. 

I love working with others at all levels of the organisation and in all portfolios. No two days are the same and I enjoy the variation. It’s important to spend time visiting our colleagues in all laboratories across the state, and I really enjoy spending time in the regional areas and getting across to all our metropolitan services.

Nicole Tripney, Executive Director, Strategic Communications  

I’ve been working with NSW Health Pathology since January 2017 and been part of our Strategic Leadership Team in my current role since October 2017.  With over 16 years’ experience in healthcare communications, I’ve worked for global healthcare PR agencies and most recently as a Team Leader for External Communications and Media Relations with Pfizer UK. The opportunity to help shape and deliver statewide pathology and forensic services that make a genuine difference to the people of NSW from before birth to death is a real privilege.

Being able to shine a light on the many experts working behind our lab doors is humbling. No two days are ever the same, which means that I am able continue to learn new things and quench my curious nature for all things science and medicine.  Plus, I’m surrounded by an amazingly talented team who always demonstrate our caring, connecting and pioneering spirit.

I’ve also worked at Hunter New England Local Health District for over 10 years in various leadership roles. I was drawn to the culture and leadership of NSW Health Pathology. Forensic medicine and the forensic & environmental sciences are incredibly interesting. It directly impacts the lives of people and I was attracted by the opportunity to help improve the experience of families and members of the community.

We have a fantastic team working across forensic medicine and the forensic & environmental sciences, who provide independent, objective analysis to the NSW health and justice systems. No day is the same and it’s rewarding to know our efforts are helping to protect and enhance the health, safety and wellbeing of our local communities.
