Aleesha Kalulu and Caroline Van Gemert come from entirely different worlds; one raised in a rural village in Vanuatu, the other a seasoned epidemiologist from Australia with decades of experience in the Pacific. But their paths converged at a critical moment in history: the COVID-19 pandemic. This is their story.
Aleesha
I fell in love with public health growing up in Pango village, seeing how our health workers help people around them with limited resources, doing the best they can with what they have. After finishing high school at Malapoa College in Port Vila, I was fortunate to receive an Australian Awards Government scholarship to study public health at the University of Canberra.
When I returned home in June 2020 – in the middle of the COVID-19 pandemic – I was eager to start working in the Vanuatu health sector.
I applied at several places, but nothing came through. For months, I stayed home, feeling stuck and unsure of what direction my career would take. Eventually, I applied for a teaching assistant role at Port Vila International School (PVIS). It wasn’t part of my plan, but I needed something to keep moving forward.
Caroline
I spent years working across the Pacific working in public health and helping to manage the spread of infectious diseases like HIV, Hepatitis B, and outbreak prone infections such as influenza. When I first arrived in Vanuatu in early 2020, it was because my husband had accepted a teaching role at PVIS as a maths teacher.
But for me, it was also an opportunity to continue my career in research, epidemiology and global health. I had received some research funding to do research on Hepatitis B in Vanuatu.
However, this was put on hold when COVID-19 emerged, and I joined the Vanuatu Australia Health Partnership as an epidemiologist to support the National Surveillance Unit at the Ministry of Health.
Aleesha
I met Caroline through her husband, who was also a teacher at PVIS. He knew about my attempts to work in health and asked if I would be interested in meeting his wife. Shortly after meeting Caroline, she offered me an opportunity to join the surveillance team.
By March 2021, I was working with the Ministry of Health as a surveillance assistant. We were preparing for a possible COVID-19 outbreak in Vanuatu, and our work focused on setting up systems to track cases, manage quarantine and monitor vaccine safety. I felt like I was finally doing what I was trained for.
Caroline
Meeting Aleesha was unexpected. My husband mentioned a young woman at the school who had studied public health but wasn’t working in the field. We decided to invite her over for dinner, and I was blown away by how clever and astute she was.
It was obvious she had the potential to contribute far beyond the classroom. I managed to vouch for her to join the surveillance team, and the Vanuatu Australia Research team funded a position for her to work with us under a contract. Even though our team was small, we were responsible for providing technical advice for the entire country.
Aleesha
Working in surveillance opened my eyes to epidemiology. I started to understand disease patterns – who is affected, where outbreaks occur and how they spread. Everyone banded together to help their communities, especially in a time as scary as the pandemic, where we really didn’t know what was happening.
Caroline was my first exposure to the field of epidemiology, and so after setting up the vaccine safety surveillance system, I started learning about disease surveillance more broadly, and more in-depth epidemiology. It made me realise how important data and research are in making decisions that help communities.
Caroline
The COVID-19 response required quick thinking and strong collaboration, and Aleesha quickly became an essential part of that effort. She helped monitor quarantine systems, supported the outbreak response and played a key role in vaccine rollout monitoring.
At the end of 2022, I left the Vanuatu Australia Health Partnership and returned to my research with the Burnet Institute on how to prevent infections like HIV, Hepatitis B, and syphilis being spread from mother to child.
I remained in Vanuatu until the end of 2024, living opposite some of Aleesha’s family in Pango, and we set up a Burnet Institute office in Vanuatu in 2025, of which Aleesha is an important part of.
Aleesha
After my contract with the Ministry of Health ended in 2024, I joined Caroline at the Burnet Institute as a research officer, focusing on maternal and child health, and preventing mother-to-child transmission of diseases like Hepatitis B, HIV and syphilis.
What I’ve learned is that research isn’t just about collecting data, but about making sure that what we do benefits people – working with communities, listening to them and designing solutions that fit their realities.
Caroline
What stood out to me was Aleesha’s ability to connect with people at every level. During our work in Vanuatu together, she was able to connect with pregnant women from the communities we travelled to about the benefits of the work we do. She even created a Bislama video to explain our research to pregnant women, which made our work more accessible and impactful.
She is an excellent communicator of science – whether she is speaking with community members, nurses or government officials. That’s a rare skill, and it made a significant difference in how our work in Vanuatu was received.
Caroline
One of the biggest challenges we faced was that research is not always seen as a priority in Vanuatu.
There’s often a perception that action matters more than analysis. But good research ensures that action is effective. It helps us understand what communities truly need and how best to deliver it.
Aleesha played a critical role in bridging that gap. She understood the local context and could translate complex ideas into something meaningful for communities.
Aleesha
There are moments that stay with you, and one for me was the December 2024 earthquake – I was inside a building that was later condemned and demolished. It was a terrifying experience, but in that moment, I was focused on making sure others were safe. I sent messages to our team, checking on everyone, and letting our team in Australia know we were safe.
Even after that, many of us continued working to support the response. It showed me how resilient our health workers are and how deeply committed people are to helping others, even in the most difficult circumstances.
Caroline
That moment during the earthquake really showed Aleesha’s character. Whilst it was obviously very frightening, she remained calm and focused on helping others. That kind of leadership can’t be taught – it comes from within.
I see her future clearly. She will go on to lead her own research programs and mentor others, just as she has been mentored. My role is simply to support her in getting there.
Aleesha
Having someone believe in you, guide you and challenge you makes a huge difference.
I’ve learned that it’s possible to pursue your goals, build a career and still stay connected to your community. And one day, I hope to do the same for others by mentoring and supporting the next generation, just as Caroline has done for me.
Caroline
Watching Aleesha grow has been one of the most rewarding parts of my work. She’s not just a strong researcher, but a leader. I trust her judgement, especially when navigating complex situations with government and communities. And she is a mastermind about everything.
One of my proudest moments was when she was accepted into the London School of Hygiene and Tropical Medicine to pursue her master’s in epidemiology. It’s one of the top institutions in the world and balancing that alongside her work is no small achievement. It speaks to her dedication and capability.
Aleesha
My relationship with Caroline has grown beyond just work. We’ve shared meals, spent time with family and built a genuine friendship. I have visited her in Melbourne, stayed with her family, been on outings with her children and experienced a different side of life.
Seeing how she balances her career and family has been incredibly inspiring. It showed me that women can have both and that you don’t have to choose between a successful career and a fulfilling personal life.
Caroline
Those moments outside of work matter just as much. Even though I don’t usually drink kava, I’ve joined in occasionally with Aleesha.
Our connection goes beyond our professional roles. We have a deep respect for each other and a shared commitment to public health and making a difference.
I really want to see her growing her technical skills and one day leading her own research study in Vanuatu.
